Sherry Flashcards
WSET D5 Chapter 3
What is Sherry
A fortified wine made in the area around the city of Jerez in Andalusia
How far does Sherry date back?
To the rule of the Phoenicians
When was Sherry ruled by the Moors? What were the implications?
Moors ruled from 8th to 13th centuries
wine consumption was prohibited but vineyards and production continued (for trade)
When did Sherry come under Christian rule?
What were implications?
13th century came to Christian rule
Domestic consumption and exports grew rapidly as English, Irish and Flemish traders began to ship the wines (and end of Moorish rule meant consumption could be allowed)
As Sherry’s popularity grew in the late 19th/ early 20th century, what happened to Sherry?
Sherry’s popularity brought poor-quality imitators
In 1933 Spain’s 1st Regulatory Council - the Consejo Regulador was formed to set regulations to control production and trading of Sherry
When did Sherry sales reach their peak?
How many hL?
What happened after Sherry’s peak?
in the 1970’s (1979) reaching 1.5MM hL (150MM liters)
shipments halved as younger generations sought out different wines
What company is associated with Sherry’s misfortunes? Why?
Ruiz Mateos SA, aka Rumasa
They built a Sherry empire, then drove prices down
in 1983 the gov’t nationalized Rumasa claiming unpaid taxes
The co’s Sherry bodegas were sold causing substantial rise in unemployment and social unrest
What is the location of Sherry w/in Spain? Latitude? Altitude?
Southern Spain, in Andalusía
36 N Latitude (generally low for wine)
low altitude (0-90m above sea level)
What is Sherry’s climate?
Hot Mediterranean
hot, dry summers and mild, rainy winters
What climatic forces are important in Sherry?
The Poniente wind - a cool, damp wind from the Atlantic, providing cooling, humid influence in the summer
The Levante - a hot, drying wind from N Africa that makes it more arid
Define poniente
A cool, damp wind from the Atlantic, providing cooling, humid influence to the Sherry region in the summer
Define levante
A hot, drying wind from N Africa that makes the Sherry region more arid
How does the levante affect the grapes?
The hot, drying wind can cause grapes to transpire more quickly, concentrating the sugars
Too much sugar can be a negative b/c it may become more difficult to ferment the wine to dryness
Flor yeast needs wines to be fermented to dryness, so this is important to Sherries that are biologically aged
Is Sherry generally cloudy or sunny? What are the implications?
Generally a high # of cloud-free days
Sunlight hours in growing season are high, helping to fully ripen grapes
But, if shading is insufficient, grapes can become sunburned
Where must the Sherry grapes come from to be labeled as DO?
Which appellations?
What exceptions?
From: the delimited area of around 7k hectares known as the Zona de Producción or Marco de Jerez
Appelations: DO Jerez-Xérès-Sherry, DO Manzanilla - Sunlúcar de Barrameda (or Sherry vinegar)
Exceptions: PX can be grown around Montilla but matured in the Zone de Crianza and still be labeled DO Jerez-Xérès-Sherry
Where are Pedro Ximénez grapes grown?
Around Montilla, within Andalusía, in the mountains above Malaga, but outside the Zone de Producción where other Sherry grapes are required to be grown
Describe the Zona de Producción
- What is it?
- How large?
- What sub-areas?
aka Marco de Jerez
The designated vineyard area for Sherry (exception made for PX)
About 7k ha
Split into 2 parts: Jerez Superior (better sites, on albariza soil, 90% of plantings), and Jerez Zona
What are “pagos” in Sherry?
Smaller delimited areas
Thought to produce wines w/ different characteristic than the others, due to aspect, location, soil differences, etc
Are “pagos” named on Sherry labels?
Legislation to allow producers to name a pago on their wine label is currently under discussion
Describe the key soil types of Sherry
Albariza: mixture of limestone, silica, clay; vast majority of plantings
Barros: greater clay content
Arenas: sandy
What are the important characteristics of Albariza?
- Mix of limestone, silica, clay
very effective at retaining and gradually relating water from the winter rainfall - Forms a crust when dry which helps reduce evaporation from soil surface
retains water, allowing for higher planting densities than elsewhere in Spain - Light color reflects light back into the vine canopy, aiding ripening
What are the typical yields in Sherry?
How does this compare to other areas of Spain?
Why is this significant?
Average yields = 70 hL/ha (compared to 80 hL/ha max allowable)
Higher than other areas of Spain
Grapes do not need to have same concentration of flavors as grapes for unfortified wines (flavors come from winemaking/maturation process)
What is the principal grape of Sherry and its aliases?
- Palomino, aka Palomino Fino and Listán
What % of production of Sherry comes from the Palomino grape?
- PRIOR: Almost 99%
- NEW BOOK: 97%, with the balance evenly split between PX and Moscatel
Describe the general characteristics of Palomino (ripening, yields, aromatic character, etc.)
Mid- to late-ripening
Suited to dry, sunny weather
Capable of producing large yields
Loses acidity quickly
Neutral (does not add much primary aroma to wines)
What % of Sherry production comes from Moscatel?
- PRIOR: Less than 1%
- NEW book: ~1.5%
Which Muscat variant is Moscatel used for Sherry? What is its alias in Sherry?
Muscat of Alexandria
Muscatel de Chipiona, after the coastal town of Chipoina where it is mainly grown
What are the main soils for Muscat in the Sherry region?
- Arenas (sandy)
Describe the main characteristics of the Moscatel grape (ripening period, main uses, aromatic character, etc.)
Late ripening
Adapted to heat & drought
Aromatic (grape, blossom)
Generally used for sweet fortified of the same name
What % of Sherry production comes from PX?
- PRIOR: Less than 1%
- NEW book: ~1.5%
What is PX used for?
Production of sweet fortified wines called PX or Pedro Ximénex
As a sweetening agent (Medium and Cream style Sherry)
Describe the general characteristics of PX (ripening, berries, aromatic character, etc)
Small, thin skinned berries
Accumulate high levels of sugar and then traditionally dried in the sun to further concentrate sugar
Neutral variety
Flavors come mainly from drying and maturing processes
Where is PX grown?
In the Montilla district in the province of Córdoba —> shipped to the Zona de Produccion either as fresh or raisined grapes, or as a young wine
How are the vineyards of Sherry changing?
They are in the process of being transformed, mainly to accommodate mechanization of all the annual tasks including pruning, harvesting, soil management
What is the principal training system used in Sherry historically? How is that changing?
Historically, used to be replacement cane pruning (here: ‘vara y pulgar’)
Now, increasingly cordon trained (single or double) and spur pruned, more suitable for mechanization
VSP trellising ensures open canopy and easy mechanization (but some shading needed to avoid sunburn)
Describe the row spacing in the vineyards of Sherry
Within-row spacing can be tight (just over 1m)
between-row spacing is wide enough to allow tractors to pass
What are the max yields permitted for Sherry? How does this compare to average yields?
max yield = 80 hL/ha
avg yields usually closer to 60-70 hL/ha
Where is albariza soil mainly found?
- On gentle slopes, 10-15%
What water management techniques are used in Sherry?
What is the process called?
Each year after harvest the soil is worked to create a series of droughts or gullies down each row of vines to catch the winter rains
Without this, the rainwater would flow down the sloped vineyards other than permeating the soil
The process is called “aserpia”
What are the most common rootstocks used for Sherry?
All are hybrids of V. vinifera and V. berlandieri
333EM
41B
13-5EVEX - developed by the local viticultural research station and considered the most successful to-date.
13-5EVEX is tolerant to limestone soils (preventing the vine from suffering fro chlorosis) and drought while also producing good yields
What are/are not issues for growing grapes in Xerex?
What are the mitigation methods?
Frost is NOT an issue (due to influence from Atlantic and hot climate)
Dry growing season means little disease pressure
Mildew can be a problem in the spring due to warm humid weather after any rain
VSP training helps promote air circulate to reduce development mildew diseases but sometimes use fungicide if needed
European grapevine moth is a problem, managed w/ pheromone traps
When is harvest for Palomino Sherry?
Why?
Begins 1st week of August starting on the more inland vineyards and finishing with cooler coastal plots by 2nd week in Sept
Tends to be as early as possible avoid risk of autumn rain and maintain acidity levels
Any rot would be undesirable, particularly for biologically aged wines
What is the typical potential alcohol at picking for Sherry? Acidity?
Why?
Typically ~12% potential alcohol
Total acidity of around 5 g/L and pH of 3.3-3.5
Palomino loses acidity quickly in final stages of ripening so acidification is sometimes required if TA falls much below 5 g/L
When are PX and Moscatel typically harvested?
Why?
Typically slightly later than Palomino (which starts early Aug and goes —> early Sept)
Higher concentration of sugar in grapes when harvested makes the drying process easier and quicker
How much of the grape harvest for Sherry is mechanized? What does this allow?
~60% is machine harvest
This allows harvesting to be mostly done at night when it is cooler, to reduce chances of oxidation and microbial spoilage
Does Sherry production typically involve skin contact?
Why?
Skin contact is not desirable, particularly for biologically aged wines
Phenolic compounds can restrict the growth of Flor yeast
These styles typically are made from free run juice and the lightest pressings (Primera yema)
Oloroso wines tend to be made from later press fractions that are extracted using greater pressure
What is the name for the free run and lightest pressings in Sherry production?
- primera yema
What pressings are used for Biologically aged Sherry wines?
Why?
Primera yema/ free run and lightest pressings
Phenolic compounds that come with later pressings can make it difficult for flor to develop
What pressings are used for Oloroso wines?
Typically later press fractions that use greater pressure than the primera yema
What are the final/later press fractions used for in Sherry production?
Other products, such as the wine used for seasoning barrels (or Sherry vinegar)
What is the maximum JUICE yield in Sherry production (L/kg)?
Max 70 L/100kg of grapes
What % of the juice yield is typically considered to be free run and 1st pressings?
60-75% of the juice yield
Briefly describe the main initial winemaking steps for Sherry (pre-maturation)
Grapes pressed on arrival at winery
Skin contact not desirable
Free run + early press fractions (primera yema) used for biologically aged wines
Later press fractions used for Oloroso wines
Final press fractions used for other products
Must is clarified before fermentation either by cold settling, centrifugation or flotation
Most use cultured yeasts
Fermentation at around 22-26C/72-79F in SS vessels (some use barrels for body)
1st phase of ferment is generally quick and not particularly cool
Most sugar fermented in 1st 7 days
then slow phase of ferment where rest of sugar is fermented (couple of weeks)
MLF prevented to retain acidity
Each batch of base wine tasted and sent for analysis - First Classification
Those designated for biological aging fortified to 15-15.5%
Those destined for oxidative aging fortified to 17% ABV
Both use 95% grape spirit that does not add aroma/flavor
After fortification they are in stage called “sobretablas” where they are stored before joining the solera system
Biologically aged wines will go to Second Classification
Why is clarification of particular importance in Sherry production?
The albariza soil is dusty and therefore clarification is important to remove these particles
