249
Q

liqueur de tirage

A

mixture of wine, sugar, yeast, yeast nutrients, and clarifying agent added to blend of base wine to start 2nd alcoholic fermentation in production of sparking wines
Raises alcohol 1.2-1.3% abv and CO2 generated by yeast dissolves into wine creating bubbles

250
Q

Riddling

A

Moving sparkling wine bottle very slow from horizontal to an inverted vertical position in order to dislodge yeast sediment so it gradually slides down side of bottle and collects in plastic cup insert in crown cap

Amount of sugar used will determine the final level of sweetness in the wine and is known as the dosage - used to balance acidity and helps with flavor development. Brut Nature has no sugar added at this stage.

254
Q

Transfer Method

A

Avoids riddling and disgorgement.Bottles are disgorged into sealed tank under pressure, wine in tank is filtered to remove yeast, liqueur d’expedition added, and wine rebottled.

255
Q

Tank Method

A

Retain flavor of base wine - good for Muscat and Riesling, and for Prosecco.

First fermentation in temp controlled stainless tanks - no MLF or oak ageing.
Yeast, sugar, yeast nutrients, and clarifying agents added to the wine and second fermentation takes place in sealed tank
Wine is filtered to remove yeast lees before it is bottled under pressure. Most have no autolysis because no time on lees.

style determined by 1) timing of harvest 2) when wines are fortified and 3) length and type of aging
grapes picked while ripe and healthy, but to make more luscious style, some raisining may be allowed to happen before picking
Fermentation takes place on skin
Luscious style - fortification may take place when fermentation reaches 2% abv
Wines undergo oxidative aging that can last for decades
old wood is essential - usually large oak vessels
may be aged in warm conditions
As they age, wine becomes amber and then brown and develop pronounced oxidative aromas

What are the 2 main species of grape vines?

A
  1. Vitis vinifera
  2. North American Vines (3 chief species):
    Vitis labrusca
    Vitis riparia
    Vitis rupestris
308
Q

What are 3 different ways a vine can be propagated?

A
  1. Clonal selection: when beneficial mutations occur in a vine and a nursery or viticulturist isolates and propagates the new, positive characteristics;
  2. Cutting - (aka Massale Selection) when a section of a shoot is cut off from an existing vine and planted in order to grow a brand new plant. Viticulturists do this to safeguard and perpetuate the positive characteristics of the original plant;
  3. Layering: A vine’s 1 year-old cane is bent into the ground and partially buried with the tip of the cane poking out above ground; the buried part grows roots and establishes itself as a new plant.
309
Q

What is head grafting and why is it used?

A

Head grafting is when a vine’s top, or head, is cut off its trunk and the cutting of a new variety is grafted on to where the old head was.

The purpose of head grafting is to switch out grape varieties instead of uprooting and replanting an entire vineyard. Head grafting is a lot less expensive than replanting an entire vineyard with the added bonus of keeping the established trunk and roots.

310
Q

Name 3 different ways to create new grape varieties.

A

Cross-Fertilization
Crossing
Hybrid

311
Q

What is the difference between crossings and hybrids?

A

Crossings: when a new grape variety is created by crossing parents of the same vine species, e.g. Cabernet Sauvignon (Sauvignon Blanc x Cabernet Franc - both V. vinifera).

Hybrids: when at least two different vine species, usually a North American vine and a vinifera vine, are crossed to create a brand new vine species, e.g. Concord and Vidal Blanc (only 1 parent is V. vinifera).

312
Q

What is the crossing of Müller-Thurgau?

A

Riesling x Madeleine Royale

313
Q

Of the two main vine species, which one is more resistant to phylloxera? How does it protect itself?

A

North American vine species are more resistant to phylloxera. It is for this reason American rootstocks are widely used across the world.

The North American vine protects itself from phylloxera by seeping a sticky sap that inhibits the louse from eating, and the vine generates a defensive layer behind a wound which prevents the louse from damaging the plant material further.

314
Q

What are the 4 main parts of a vine?

A

Roots
Permanent wood
1 year-old wood
Green parts (also known as the canopy: leaves, grapes, tendrils, etc.)

315
Q

What is the difference between a cane and spur?

A

They’re both 1 year-old wood from the previous year’s growth. However, the main difference between them is how may buds each has.

Cane: a long woody branch with 8 to 20 buds

Spur: a short woody branch with only 2 to 4 buds

316
Q

What are the 2 main types of vine training?

A
  1. Head trained
    usually just a trunk with a couple of spurs or replacement canes, no permanent “arms”;
  2. Cordon trained
    a trunk with one or two permanent arms, or “cordons”, that look like a bent extension of the trunk.
317
Q

Give 2 examples of head-trained vines.

A
  1. Guyot
  2. Bush

Bush vines tend to produce a lush canopy, so they perform best in hot regions such as Jérèz or Southern Rhône where the grapes need the extra shade.

Bush vines are generally head-trained and spur-pruned (meaning, 2-4 buds on each 1 year-old growth).

318
Q

On what training system are you most likely to see replacement-cane pruning?

A

On head-trained vines.

If a head-trained vine has 1 cane, it’s called Single Guyot.

If a head-trained vine has 2 canes, it’s called Double Guyot

319
Q

What is transpiration?

A

Transpiration is how a vine takes water up through its roots and disperses it to its leaves.

320
Q

Describe Vertical Shoot Positioning (VSP).

Where is VSP commonly seen?

A

VSP is commonly seen in cool climates.

VSP is a cordon-trained vine whose shoots are positioned in an upward direction attached to the wires that connect posts within a row in a vineyard.

Attaching the canopy to wires allows air circulation and the grapes to be exposed to direct sunlight.

321
Q

What are high-trained and low-trained vines?

A

High-trained vines are vines that are trained high off the ground to avoid frost and humidity.

Low-trained vines are vines that are trained closer to the ground so the grapes can benefit from radiating heat coming off the ground.

322
Q

What are the 5 most important things a vine needs to survive?

A 
Heat
Water
Sunlight
Nutrients
Carbon dioxide
323
Q

What are the top three most important nutrients for vines?

327
Q

Frost is most dangerous around which phase of the vine’s annual cycle?

What are some adverse effects from frost?

A

Budburst is when frost is most dangerous (March/April in Northern Hempishere, Sept/Oct in Southern Hemisphere).

Adverse effects:

if frost occurs right before budburst, it can delay budburst which means the grapes are at risk of not fully ripening before autumn;
new plant material can freeze and die;
spring frost damage can decrease the annual yield;
fungal diseases can develop if the weather stays wet.

328
Q

What is Coulure?

A

Coulure is poor flower set due to cold or rainy conditions or poor fertilzation. The flowers drop from the cluster, known as “shatter.”

A

Millerandage

330
Q

During the summer months, what vineyard management techniques help control the quality and ripeness of the grapes?

A

Green harvesting: dropping underdeveloped clusters right after véraison so the vine puts its energy into the remaining clusters;
De-leafing: removing leaves near the fruit zone so the grapes see more direct sunlight.

Q

What are 3 reasons for trellising vineyards?

A

1) Arrangement of young shoots can be used to control amount of sunlight that gets into the canopy (regions with limited vs. intense sunlight)
2) Open canopy can improve air circulation through the leaves and grapes - important in wet climates to reduce risk of fungal diseases
3) Aid mechanization in the vineyard - positioning grapes in one area of vine and leaves in another enables mechanization and more effective spraying of insecticides and fungicides

362
Q

Besides clay, what soil element is known for good water retention?

A

Humus, which is organic matter made up of decomposing plant and animal materials.

363
Q

What is the composition of loam soil?

A

Loam is a mixture of sand and clay. It has both good water drainage and retention due to its composition.

364
Q

How often is a vineyard typically replanted?

A

About every 30 to 50 years.

365
Q

Name some vineyard pests other than phylloxera

A

Birds
Deer
Nematodes
Insects

366
Q

What are nematodes, and what damage can they cause to a vine?

A

Microscopic worms that eat the roots of vines, leaving open wounds through which viruses are known to enter.

Nematodes spread one particularly damaging nepovirus that causes Fan Leaf Degeneration, which deforms shoot growth, leads to poor fruit set, and reduces yields. Affected vines must be removed, they cannot be grafted.

367
Q

Name 3 fungal diseases.

A

1) Downy mildew
2) Powdery mildew
3) Grey Rot

368

2) Harvest grapes earlier - med body and alcohol, but higher acid, fresh red fruit, vegetal and leafy aromas. Rarely found outside Bordeaux.

369
Q

Describe sustainable agriculture

A

Use of synthetic chemicals is restricted but not prohibited;
Spraying or applying chemicals only when needed;
practicing Integrated Pest Management - introducing natural predators to control pests;
Creating biodiversity in the vineyard.

370
Q

Describe organic viticulture.

A

Synthetic chemicals not allowed;
The only real chemicals allowed are sulfur and copper, and their applications are restricted;
If a winery wants to be certified organic, they must apply for accreditation with one of the certifying bodies and work their vineyard organically for at least 2 years prior to certification.

371
Q

Describe biodynamic agriculture.

A

Biodynamics is much more than a method, it is a spiritual science, a belief system — a holistic way of seeing and understanding the natural world that focuses on regenerative practices.
Biodynamics sees the vineyard as an ecological whole: not just rows of grapevines, but the soil beneath them—an organism in its own right—and the other flora and fauna in the area, growing together interdependently.
Where biodynamics differs from organic or sustainable agriculture is in its idea that farming can be attuned to the spiritual forces of the cosmos. This might mean linking sowing and harvesting to the phases of the moon or the positions of the planets.

372
Q

What is chlorosis?

A

Chlorosis is a nutrient deficiency in the soil that affects the vine’s ability to photosynthesize. A sign of chlorosis is yellow leaves and poor overall growth. Grapes struggle to ripen property and quality/quantity is reduced.

The usual cause for chlorosis is a lack of iron in the soil. Farmers will either add iron-rich fertilizers.

373
Q

What are the advantages of mechanical harvesting?

A

1) fast
2) efficient - berries are shaken from stems so there is no need for a destemmer
3) decreases number of laborers
4) can be done overnight which saves costs on lowering grapes’ temperatures prior to processing them.

374
Q

What are the advantages of hand harvesting?

A

1) easier to control grape quality;
2) usually less berry damage, therefore fewer oxidation issues;
3) whole clusters are picked which keeps stems intact;
4) In some places (usually steep and/or with terraces built centuries ago), handpicking is the only option, e.g. Mosel, Valtellina, Northern Rhône.

375
Q

Define a maritime climate

A

Cool to moderate temperatures and low annual difference between hottest and coldest months (low continentality). Rainfall evenly spread throughout year which moderates temperature, resulting in temperatures warm enough for grapes to continue ripening into fall.

Rainfall in spring and summer can be harmful to flowering, fruit set, and health of grapes at harvest

Bordeaux and Rías Baixas are examples of Maritime climates.

376
Q

Describe Mediterranean climate.

A

Low temperature difference between hottest and coldest months, summers tend to be warm and dry. Most rainfall is in winter.

lead to wines that are fuller bodied, riper tannins, higher alcohol, lower acidity.

Ex: coastal California, Chile, South Africa, South Eastern Australia

377
Q

Describe Continental climate.

A

Greatest difference in temperature between the hottest and coldest months (high continentality). Short summers with large, rapid temperature drop in autumn. Dry summers.

Cool continental (e.g., Chablis and Champagne) at risk for spring frost, low temps can affect flowering, fruit set, and ripening.

Best suited to varieties that bud late and ripen early

378
Q

What natural factor plays the largest role in influencing California’s vineyard climate?

A

California Ocean Current

latitude plays relatively small role. Mountains along coast shield much of state from cooling effects

379
Q

What is the rain shadow effect?

A

As weather systems move from west to east, foul weather is stopped by or trapped in mountains thereby leaving the eastern side of mountains with brilliant sunshine and nice weather. The western side gets all the rain and clouds.

The Vosges, Cascades, and Andes Mountains are all examples of mountain ranges that create rain shadows.

380
Q

What is diurnal shift?

A

Change in temperature from daytime to nighttime.

The larger the diurnal shift (lower lows, higher highs) the better it is for the vine; warm daytime temps help develop sugar and phenolic ripeness whereas cool nighttime temps help preserve acidity and freshness.

381
Q

What happens to a vine when it suffers from drought conditions?

A

A vine will shut down if it doesn’t have enough water to produce photosynthesis.

leaves will stop all work
sugars won’t be produced
grapes won’t ripen properly

382
Q

Why is rain at harvest not a good thing?

A
  • Dilution of flavors in grapes
  • Dilution of sugars in grapes
  • Create rot
    This is why winemakers will have to decide to pick either before a big rain or wait several days after the rain for the vines to metabolize the rainwater.
383
Q

Explain véraison.

A

The onset of ripening and when the grapes change color.

Red varieties turn from green to purple or black, and sugars increase while acidity levels decrease.

384
Q

What are some important considerations winemakers have to weigh before processing and fermenting white grapes?

A 
Length of skin contact, if any
Fermentation temperature
Fermentation vessel
Use of lees
Malolactic fermentation
385
Q

What are some commonly practiced must adjustment techniques?

A
  • Enrichment - adding sugar via RGCM or a non-grape source (Chaptalisation)
  • Remove water from juice to concentrate sugars
  • Acidification
  • Deacidification
386
Q

Which acid is typically used to acidify a wine?

A

Tartaric acid

387
Q

How is a wine deacidified?

A

By adding an alkali (an acid neutralizer).

388
Q

What is the most common must adjustment made to white grapes from warm/hot climates?

A

Acidification

389
Q

What is chaptalisation?

A

Adding sugar before or during fermentation in order to increase the alcohol level in a wine.
Beet and cane sugar are the most common forms of sugar used.

390
Q

Why do most white wines spend little time in contact with their skins?

A

Reduce the risk of oxidation and the extraction of unwanted flavors.

391
Q

Why would some winemakers keep white wine juice in contact with the grape skins?

A

Skin contact increases flavor intensity and texture

392
Q

When are grapes for white wines pressed?

A

Before fermentation (ideally, shortly after they’re harvested and brought to the winery)

393
Q

What techniques can a winemaker use to clarify the must of a white wine?

A

1) Fining
2) Filtration
3) Settling
4) Centrifugation

394
Q

What can happen to a white wine if the winemaker does not clarify the must adequately?

A

Unpleasant aromas can form from microbiological issues and fermentation may stop.

395
Q

Why do some winemakers chose not to over-clarify their white wine musts?

A

Some winemakers believe that having a small amount of grape solids in a fermenting must will make the resulting wine less prone to oxidation; additionally, they feel these solids will contribute complex flavors and a more pleasing texture to the final wine.

396
Q

What is the most commonly used yeast strain in winemaking? Why is it preferred?

A

Saccharomyces cerevisiae

This yeast strain is preferred because of its hardiness against SO2 and elevated levels of alcohol.

397
Q

What sugar supports vine growth and makes grapes taste sweet?

A

Glucose

398
Q

What aspects of winemaking will determine the speed of fermentation?

A

1) Type and quantity of yeasts;
2) Nutrient content in the must;
3) Concentration of sugars in the must;
4) Temperature (warmer temperatures mean faster fermentations);
5) How much SO2 is used (too much slows fermentation).

399
Q

What is the optimum fermentation temperature for white wine?

A

Between 12°C - 22°C (54°F - 72°F)

400
Q

What may happen if white wines are fermented at too low a temperature?

A

Yeasts may go dormant, but they can be woken up with an increase of heat;
Low fermentation temperatures may result in “pear drop” or pear candy aromas and may prevent a grape’s true varietal aromas from developing.

401
Q

What may happen if white wines are fermented at too warm a fermentation temperature?

A

Yeasts may die;
Hot fermentation temperatures will sometimes create unappealing aromas, and there is a risk that the classic varietal character will be lost in the process.

402
Q

What kinds of vessels are commonly used to ferment white wines?

A

Steel tanks
Oak barrels
Concrete

403
Q

What are the advantages of fermenting white wines in stainless steel?

A

Stainless steel is inert (non-reactive), which helps maintain varietal character;
Temperature control systems are easier to build into stainless steel fermenters than oak or cement.

404
Q

What are the advantages of fermenting in oak barrels?

A

Oak barrels are known to transfer heat effectively;

Oak barrels will add richer flavors and rounder textures.

405
Q

What will cause a fermentation to cease (aka a stuck fermentation)?

A

All available sugar in a must is consumed;
Yeasts run out of nutrients to metabolize;
Temperatures exceed 35ºC (95ºF)

406
Q

What are some important considerations winemakers must take into account post-fermentation in re: white wines?

A

What vessel to use (oak, stainless steel, etc.)
Whether to blend or not;
Whether to lees age or not;
Whether to allow, actively encourage, or completely block MLF;
Whether to fine or filter the wine, and how much.

407
Q

What are some of the benefits of blending white wines post-fermentation?

A

1) improve consistency, texture, or flavor;
2) enhance balance;
3) create wines of a particular or desired style.

408
Q

What flavors will aging in new oak add to white wines?

A

Oak aging is known to add flavors of vanilla, toast, bread, clove, dill, nutmeg, coconut, butterscotch, anise, and smoke.

409
Q

What less-costly methods may be substituted for oak barrels but still add desirable oak flavors to value-priced white wines?

A

The use of oak staves or oak chips.

The oak flavors will be less well integrated into the final wine as oak barrels do more than just add oak flavors, which is why this cheaper method is never used for premium white wines.

410
Q

What is malolactic fermentation?

A

Conversion of tarter malic acid (the same acid in an under-ripe apple) into softer, creamier, lactic acid (the same acid in milk or yogurt).

411
Q

What are some notable effects of malolactic fermentation?

A

Lowers overall acidity;
Creates buttery aromas
Creates a little CO2

412
Q

What are some ways to prevent malolactic fermentation?

A

Adding SO2 after primary fermentation completes;
Storing the wine at cool temperatures;
Sterile filtration

413
Q

What are some ways to encourage malolactic fermentation?

A

Not adding SO2 or keeping levels very low;

Warm storage temperatures.

414
Q

What white grape varieties are most likely to undergo malolactic fermentation?

A

Chardonnay and Viognier

415
Q

What’s the difference between fining and filtering?

A

Fining removes the small stuff you can’t see - all the unstable, microscopic things in a wine (proteins, phenolic substances, etc.). If these things aren’t removed prior to bottling they can clump together later and make the wine appear hazy.

Filtering removes the big stuff you can see - all the large clumps (e.g. seeds, grape skins, pebbles, spiders).

416
Q

Winemakers should ensure their wines are stable in what three areas?

A

1) Tartrates
2) Microbiological
3) Oxygen

417
Q

How does a winemaker remove tartrate crystals?

A

By bringing down the wine’s temperature to 0ºC (32ºF) or colder for 1-2 weeks.

The crystals will preciptate out of the wine (they’re about the size of raw sugar crystals) and the winemaker filters them out.

418
Q

What kinds of wine are susceptible to microbiological instability?

What kinds of wine are not easily susceptible to microbes?

A

Susceptible

  • wines that haven’t gone through MLF
  • wines with low or moderate alcohol
  • wines low in acid
  • wines with some residual sugar

Not susceptible

  • wines high in alcohol
  • wines high in acid
  • wines that have gone through MLF
419
Q

What are the major differences between red wine making and white wine making?

A

1) White wines are usually pressed before fermentation while red wines are pressed after fermentation;
2) Red wines spend an extended period of time in contact with their skins before and during fermentation, extracting tannin and color from the lengthy skin contact whereas white wines are direct pressed;
3) Reds always go through malolactic fermentation and for whites it’s really up to the winemaker to decide whether the white goes through MLF.

420
Q

What does cold soaking do?

A

Cold soaking encourages a slow, long extraction of flavors and color (but not tannin) from red grapes at cool temperatures.

Tannins aren’t meaningfully extracted during cold soaks because tannins are more soluble in alcohol, which is present only after fermentation begins.

421
Q

What are the 5 overarching steps in traditional red winemaking?

A

1) Pre-fermentation processing
2) Alcoholic fermentation
3) Draining and pressing
4) Malolactic fermentation
5) Maturation

422
Q

What winemaking elements must be closely managed during red winemaking?

A

1) Density and temperature of the must;
2) Oxygen level of the must;
3) The cap that will be created during fermentation;
4) The duration of skin contact.

423
Q

What is the typical temperature range for red wine fermentation? What happens to the yeasts if fermentation temps get too high?

A

Between 20°C - 32°C (68°F - 90°F).

If fermentation temps go over 90ºF there’s a risk the yeasts will die.

424
Q

Why are red wines fermented at higher temperatures than white wines?

A

The higher temperatures allow for the extraction of color, flavor, and tannin which are the hallmarks of red wines.

425
Q

What is the “cap” in red winemaking?

A

The cap is the accumulated raft of skins, seeds, and other grape solids that float to the top of a fermenting red wine.

426
Q

What would happen to a red wine if the cap was not managed (punched down or pumped over) during winemaking?

A

If the cap is not managed, the resulting wine would be considerably less tannic, lighter in color, and would pack a less flavorful punch.

Off-odors would also develop as the yeasts need oxygen to survive.

427
Q

What are some of the benefits of cap management?

A

As fermentation is an exothermic reaction, pumping over, punching down, and rack-and-return reduce the heat amassed during fermentation.

These methods also allow oxygen into the must and break up the cap.

428
Q

Why must the punching down technique be practiced more carefully than other cap management methods?

A

At the end of the fermentation process, when alcohol is higher, tannins are more easily extracted from the cap and if not practiced correctly, punching down can result in an exceedingly bitter and rough final wine.

429
Q

What is one of the key advantages of using a rotary fermenter?

A

Rotary fermenters continuously agitate the cap and juice together making extraction fast but, if the winemaker isn’t careful, extraction can be too deep and intense.
Rotary fermenters are commonly used in Australia.

430
Q

What wine region is most well known for its use of both carbonic and semi-carbonic maceration?

A

Beaujolais

431
Q

How is carbonic maceration carried out?

A

Whole clusters of grapes are placed in fermentation vessels with CO2 pumped on top of the grapes. The anerobic environment will start the fermentation without yeast by using enzymes already within the grapes, converting the grapes’ sugars into alcohol.

432
Q

What aromas and flavors will carbonic maceration give to a wine?

A

Bananas
Kirsch
Bubble gum
Cinnamon

433
Q

How does semi-carbonic maceration differ from carbonic maceration?

A

Semi-carbonic does not use an initial hit of CO2 to blanket the grapes;

Semi-carbonic allows a traditional, yeast-driven fermentation at the bottom of the fermentation vessel.

434
Q

When a red wine stays on its skins after primary fermentation is finished it’s called extended maceration.

What’s the benefit of extended maceration?

A

This allows the red wine additional time to draw out further color, tannins, and other compounds from the grape solids.

Whether or not to do extended maceration is entirely up to the winemaker.

435
Q

When are grapes for red wines pressed?

A

After fermentation has completed.

436
Q

Malolactic fermentation is _______ used in the production of red wines.

A

Always

For red wine production malolactic fermentation is standard practice instead of a stylistic choice.

437
Q

Do rosé wines undergo malolactic fermentation?

A

Malolactic fermentation is avoided for most rosé production as the crisp, fresh acidity of these wines is a defining feature of the rosé style.

438
Q

What wine regions are known for making rosé wines using the direct press method?

A

1) Côtes de Provence

2) Languedoc

439
Q

Which wine regions are known for making rosé in the short maceration method?

A

1) Anjou (Loire)
2) Bordeaux Clairet
3) Tavel (Rhône)

440
Q

majority ferment and store in stainless steel, but old oak casks also commonly used. some may mature best wines in new oak barrels.

441
Q

What conditions are needed for flor to thrive?

A

Precise levels of

1) alcohol (can’t be above 15.5% abv)
2) temperature (favors cool to moderate temps)
3) humidity (favors high levels of humidity)

Grows more vigorously in spring/fall and dies back in winter/summer

442
Q

What gives biologically aged Sherries their unique flavor?

A

Acetaldehyde that is produced by flor (flor feeds off alcohol and nutrients in wine, and produces CO2 and acetaldehyde)

443
Q

Classification system is integrated into the appellation system
Within Saint-Emilion there is separate appellation Saint-Emilion Grand Cru, and within this another classification

Lower step is Saint-Emilion Grand Cru Classe
Above this is Saint-Emilion Premier Grand Cru Classe, which is sub-divided into Premier Grand Cru Classe A (the best) and Premier Grand Cru Classe B

Reclassifications of promotions and demotions at least once every 10 years.

452
Q

Burgundy Appellation Hierarchy

A

1) Regional Appellations (examples: Bourgogne Rouge or Bourgogne Blanc…more restricted areas include Bourgogne Hautes Cotes de Nuits, Bourgogne Hautes Cotes de Beaune, Bourgogne Cote Chalonnaise, Macon for red or white or Macon Villages for white wines only)
2) Commune Appellations (examples: Chablis, Gevrey-Chambertin). About 1/3 of total production.
