Q

How do bubbles get into wine?

A

A few ways:
- Force carbonation (used for low quality, inexpensive wines);
- As a by-product of fermentation, which can take place in tank or bottle (used for quality wines, e.g. Prosecco or Champagne).

Q

What is the main flavor objective for bottle fermented, or Traditional Method, sparkling wines?

A

Autolytic flavors, such as bread, toast, and biscuit.

Traditional method sparkling wines take on these bread-like flavors from their aging on the lees.

Q

In Traditional Method, what step happens after the sugar + yeast solution is added to the base wine?

A

mixture is bottled, sealed with a crown cap, and left to age for several months for autolytic compounds to develop.

Secondary fermentation happens inside that bottle and the CO2 is captured and dissolved in the wine; the CO2 will only be released when the cap is removed.

Q

What makes the Champagne region ideal for making low alcohol, high acid base wines?

A

Cool climate causing grapes to struggle with ripening
* Acidity is higher - results in lower sugars
* Yeasts eat less sugar - results in lower alcohol

- Not particularly age-worthy/better drunk young

Vintage:
- Dry
- High acid
- Mature citrus
- Bruised apple/pear notes

- Honey
- Caramel
- Mushrooms
- Extremely age-worthy/benefits from extended bottle aging

Q

What is the minimum requirement of lees aging for non-vintage Champagne?

A

12 months

22
Q

What is the climate of Catalunya?

A

Warm

23
Q

How do the grapes destined for sparkling wine in Catalunya, which has a warm climate, retain their acidity?

A

Grapes are harvested early.

24
Q

Generally, which has more pronounced autolytic aromas + flavors, NV Champagne or NV Cava?

A

NV Champagne

Cava spends less time on its lees than Champagne, which translates to less pronounced autolytic aromas in the final wine.

25
Q

Where in Spain is the majority of Cava made?

A

northeastern Spain

Most regions in Spain are allowed to produce Cava, but the majority of Cava is made in Catalunya in northeastern Spain.

26
Q

What 2 international grape varietals are allowed in Spanish Cava and what do they add?

A

Chardonnay and Pinot Noir both add acidity and fruit character to Cava.

27
Q

The majority of Cava is made by which kind of producer, small, family-run businesses or big brands?

A

Big brands, such as Freixenet

Small producers work hard at crafting delicous, quality wines that punch above their weight. Producers to look for include Raventós, Avinyó, and Recaredo.

28
Q

Besides Spain and France, name some other countries and regions make Traditional Method sparkling wine.

A
  • South Africa
  • Australia
  • New Zealand
  • California
  • Oregon
29
Q

What does the South African term Méthode Cap Classique indicate?

A

That the sparkling wine was made using Traditional Method.

30
Q

Besides Pinot Noir and Chardonnay, what other grape in South Africa is widely used in Méthode Cap Classique?

A

Chenin Blanc

31
Q

Most regions outside of Champagne receive more sunlight and are warmer in general than Champagne. What fruit profile would you expect these regions to express in their wines?

A

Riper and more ample fruit aromas + flavors.

Note that in these warmer regions the grapes are grown in the coolest spots possible to help retain acidity and freshness.

32
Q

Fill in the blank:

The sparkling winemaking method best for aromatic grape varietals is ______.

A

Tank Method

This is because it avoids autolytic aromas + flavors; autolysis is not beneficial for aromatic grapes.

33
Q

Which technique is more cost effective, Traditional Method or the Tank Method?

A

Tank Method

The Tank Method is more cost effective because the wine undergoes secondary fermentation in large tanks instead of individual bottles, and filtration and disgorgement are done in mechanized, big batches.

34
Q

What is Asti method?

A

It’s a variation of the Tank Method.

It starts with grape juice (not a dry base wine) and produces sweet, low alcohol sparkling wines.

35
Q

What Italian region does Asti DOCG come from?

A

Piedmont in northwest Italy.

36
Q

What grape goes into Asti DOCG?

A

100% Moscato

37
Q

Asti DOCG wines are fully sparkling or gently sparkling?

A

Fully sparkling

38
Q

Compare Tank Method and Asti Method - what style of wine results from each method?

A

Tank Method:
- Starts with dry, low alcohol, high acid base wine
- Dry base wine goes through secondary fermentation in sealed tank, where bubbles are created and captured
- Once secondary fermentation complete, wine is filtered off its lees and bottled under pressure
- Final sparkling wine ~11-12% abv and dry

Asti Method:
- Starts with grape juice + yeast put into tank to initiate fermentation, and bubbles allowed to escape
- Partly through fermentation tank is sealed to capture the CO2 being created
- Yeasts filtered out before fermentation complete leaving residual sugar in the wine
- Final sparkling wine ~8% abv and off-dry/sweet

39
Q

Where does Prosecco DOC come from?

A

Veneto in northeast Italy.

40
Q

What method is typically used for Prosecco DOC?

A

Tank Method

41
Q

What is the grape used to make Prosecco DOC?

A

Glera

42
Q

What are the styles in which Prosecco DOC is typically made?

A
  • Dry (Brut)
  • Off-dry (Extra Dry)
43
Q

Why is Glera (Prosecco DOC) made using Tank Method?

A

Glera is a semi-aromatic grape

Semi-aromatic and aromatic grapes produce better sparkling wines that show off their fruitiness (rather than autolytic compounds via Traditional Method).

44
Q

What labeling law is common between Champagne and Cava regarding their PDO status?

A

Neither Champagne nor Cava has to have its PDO/DO/AOC status on the label.

On their labels you will see just “Champagne” or “Cava”.

45
Q

What is the name of the process when you manipulate and encourage dead yeast cells into the neck of the bottle by gradually turning bottles from their sides until they are fully upside down on their crown cap?

A

Riddling

Today many sparkling wine houses use gyropalettes, which hold 504 bottles, to riddle their wines instead of doing it by hand.

46
Q

What is the name of the process that removes the yeast-sediment plug that collected in the neck of a Traditional Method bottle of sparkling wine as a result of riddling?

A

Disgorgement

The neck of the bottle is frozen so the plug is a solid mass, the crown cap is removed, and the CO2 pressure that built up inside the bottle is so strong it forces out the yeast plug.

47
Q

What is the liqueur d’expédition?

A

The final dosage made up of wine and (usually) a bit of sugar which tops up a bottle of Traditional Method wine to replace any wine that was lost during disgorgement.

48
Q

What does the final dosage (liqueur d’expédition) do besides top up the bottle?

A

Dictates the final sweetness level of the wine.

The more sugar in the dosage, the sweeter the final wine will be, e.g. Demi-Sec will be more sweet than Brut.

49
Q

How are Traditional Method and Tank Method bottles usually enclosed?

A

With a thick mushroom cork and wire cage.

50
Q

Describe the subsequent steps a base wine goes through for Traditional Method after primary fermentation has occurred.

A
  1. Base wine + yeast + sugar placed in individual bottles to kickstart secondary fermentation
    *CO2 and ~1.5% alcohol created
  2. Dead yeast cells (lees) start to break down, after secondary fermentation is completed, a process called autolysis
    *autolytic flavors include bread, biscuit, toast
    *the longer the wine ages on the lees, the more the autolytic flavors intensify
  3. Riddling
    *move dead yeast cells into neck of bottle by turning bottles from sides to upside down
  4. Disgorgement
    *bottle neck is plunged into freezing liquid to solidify yeast sediment
    *crown cap removed to allow yeast plug out
  5. Dosage
    * bottle topped up with wine and, most of the time, sugar which determines final sweetness
  6. Reseal bottle
