Q

How did Rumasa contribute to the fall of Sherry?

A
  • After Rumasa acquired wealth by supplying Harveys Bristol Cream, Rumasa began building a business empire
  • His empire including taking over Sherry bodegas, hotels and banks.
  • In the late 1970s it dominated the Sherry industry, and through the consolidation of production facilities, drove down Sherry prices
  • After Spain’s Government nationalized Rumasa in 1983, the bodegas it owned were sold, and a large number of others were closed leading to massive unemployment

Q

What is the Levante?

A

The Levante is a hot, drying wind from North Africa that can make the climate more arid.

  • This can cause the grapes to traspire at a quicker rate, concentrating sugars. This can be a problem as it may become difficult to ferment to dryness, which is particularly problematic for the development of the Flor

Q

How will producers in Jerez avoid MLC?

A

By chilling the must

  • It is important to note that this is preferred over using SO2 as that would negatively impact the development of the flor
51
Q

What steps are taken to decide if a base wine will be used for oxidative aging or biological aging?

A

After fermentation is completed, each batch of base wines are tasted and sent off for analysis.

  • This is known as the first classification
52
Q

Wines destined for biological aging are fortified to ________% abv

A

15-15.5%

53
Q

Why is it important for wines destined for biological aging to be at 15-15.5% abv?

A

It is the optimum concentration of alcohol needed to for flor yeast to grow

54
Q

Wines destined for oxidative aging are fortified to _____% abv

A

17% abv

At this level of alcohol flor yeast cannot survive

55
Q

Name the stage that the new base wines stay in before joining the Solera System

A
  • Sobretablas
56
Q

What does the second classification for Sherry base wines entail?

A
  • After aging in tanks or barrels during the sobretablas stage, wines that were marked for biological tasting are tasted and analyzed again:
  • Wines that have a full layer of flor and have remained fresh will be marked as potential Fino or Manzanilla
  • Wines that are slightly less delicate may be marked as potential Amontillado
  • Wines that are more full-bodied and intensely flavored may be marked as potential Palo Cortado
57
Q

Wines labelled DO Jerez-Xeres-Sherry must come from one of three municipalities, name them

A
  • Jerez de la Frontera
  • El Puerto de Santa Maria
  • Sanlucar de Barrameda
  • Together they are called the Zona de Crianza
58
Q

What is the exception to the rule of where Sherry must be matured to be called Sherry?

A

Moscatel can also be matured in Chipiona and Chiclana de Frontera

59
Q

What municipality must Manzanilla come from?

A

Sanlucar de Barrameda

60
Q

What is the most widely used oak size and type to age Sherry in?

A

600L butts, that are used American oak

61
Q

What are some architectural features of Sherry bodegas that help maintain the conditions inside them ideal with out the use of modern technology?

A
  • Thicker walls to help keep temperatures constant
  • They are taller buildings with high ceilings so the warm air rises away from the butts
  • Small windows positioned high up near the roof let in cool, damp winds from the Atlantic to enter which help lower the temperature and raise the humidity
  • Windows have thin blinds to diffuse sunlight and prevent dust/bugs from entering
  • Floors are generally made up of the earth so they can be wetted during the summers to lower temps and raise the humidity
62
Q

Why are maintaining temperature and humidity levels important?

A

They can affect the growth and maintenance of the Flor

  • Despite the design of the bodegas, there is still fluctuation in conditions between the summer and winter, therefore growth of flor can not be maintained throughout the year
63
Q

True or False,

Most Sherry is a vintage product?

A

False

64
Q

What is a criadera?

A

It is a group of barrels of wine that make up a section of the solera system

65
Q

How are the criadera named?

A

The are named according to the relative age of wine that they contain

66
Q

What is the name of the oldest criadera?

A

Solera

67
Q

What is a key rule for the solera system?

A

That no more than 40% of the wine from one solera system can be removed for blending and bottling each calendar year, making sure that most of the wine remains in the solera system

68
Q

What is the basic process for the solera system?

A
  • A proportion of wine is taken from each barrel in the solera (oldest group of barrels)
  • The same proportion of wine is taken from the barrels in the 1st criadera, blend to ensure consistency, and then used to top of the solera barrels
  • The same proportion of wines from the 2nd criadera, blended, and used to top off the 1st criadera
  • This is repeated until reaching the youngest criadera, which is topped off with wines from the sobretablas
69
Q

Is some wine for bottling removed from the solera system before it reaches the solera?

A

Yes, this is usually done due to the expense of having so much wine tied up, or for style

70
Q

What is the flor composed of?

A

4 different strains of Saccharomyces cerevisiae

71
Q

Can the flor survive at any level of alcohol?

A

No, the wine should be a maximum 15.5% abv as the yeast struggles to survive about 16% abv

  • The flor yeast also consume alcohol to survive
72
Q

What conditions need to be met to help the flor flourish aside from the 15.5% abv?

A
  • Not using SO2
  • only filling the butts 85-90% as the flor needs oxygen
  • The bodegas should be between 16-20°C(61-68°F)
  • Humidity levels above 65%
73
Q

How does the flor affect Sherry wines?

A
  • It protects the wine from oxidation, hence the wines remain pale lemon in color
  • When the flor consumes alcohol, it releases acetaldehyde which gives aromas of apple, hay, and/or chamomile
  • It consumes glycerol which can give matured wines a lighter body, and contribute to how dry the wine may taste
  • Flor also reduces the levels of acetic acid
74
Q

Does the flor stay at a constant level throughout the year?

A

No it does not. Usually in the winter the layer of flor will decrease

75
Q

What is another factor that comes into play with the flor?

A

That some of the yeast in the flor will die off and fall to the bottom of the barrel and begin autolysis, adding savory and nutty flavors, as well as texture to the wine

76
Q

What is another benefit to removing wines from the solera system and adding new wine back in?

A

It also younger wines, that are nutrient rich, to enter the solera system which help keep the flor alive.

77
Q

So to help keep the flor alive, will producers of Fino and Manzanilla sherry pull wine out just once a year, or multiple times a year?

A

Multiple times, as this has the added benefit of bottling in small batches so that the wines are not sitting in a warehouse somewhere since Fino and Manzanilla Sherry is meant to be consumed will young

78
Q

What are some of the differences between biological aged Sherry and oxidative aged Sherry?

A
  • The color, oxidative Sherry will show its age, moving from lemon to gold, amber and brown
  • Levels of alcohol will increase as water evaporates
  • Flavors become more concentrated as the water is lost
  • Glycerol levels will rise, giving the wines a fuller and rounder body
  • Flavors move from primary to tertiary and oxidative
79
Q

Due to the evaporation of the water in oxidative styles of sherry, how much volume is lost each year?

A

It is estimated that 3 to 5 percent of volume is lost each year

80
Q

What compound is associated with volatile acidity?

A

Ethyl acetate

81
Q

What are processes are done to sherry before bottling?

A

Most Sherries are:

  • Tartrate stabilized
  • Fined and filtered
82
Q

Why is it particularly important to fine and filter biologically aged Sherries?

A

Because if any of the flor yeast remain, the flor could start to develop again once the bottle it opened

83
Q

Dry Sherries have a maximum of ___ g/L residual sugar

A

5 g/L

84
Q

What is a surprising difference between biological sherry aged in Sanlucar de Barrameda and Jerez?

A

The flor in Sanlucar is generally thicker year round when compared to the flor in Jerez

  • This is generally attributed to Sanlucar de Barrameda’s proximity to the ocean, causing higher humidity and smaller fluctuations in temperature
85
Q

Since the flor is thicker in Sanlucar de Barrameda, what is something that the bodegas will do to ensure the flor stays healthy?

A

Due to the thickness of the flor, producers will pull wine out in small volumes multiple times a year so that small volumes of younger wine can be added in to support the growth of the flor.

86
Q

What is Manzanilla Pasada?

A

Manzanilla Pasada is a labeling term for Manzanilla sherry that was subjected to a short period of oxidative aging.

The flor is left to die naturally by not refreshing the barrels. This wine can may then enter a Manzanilla Pasada solera system.

These wines are on average a few years older then Manzanilla wines, any older and they start to become more like Amontillado Sherry

87
Q

How is Amontillado Sherry produced?

A

Amontillado Sherry is a wine that must have characteristics from both biological and oxidative ageing.

The wines will start in a Fino solera system, be re-fortified to 17% to kill the flor, and then matured in a Amontillado solera system.

88
Q

What is Palo Cortado?

A

It is the most difficult style of sherry to define. It must have:

  • “aromas similar to those of an Amontillado, but a palate more similar to an Oloroso”
  • Sugar level under 5 g/L
  • Alcohol between 17-22% abv

As long as the parameters above are met, there are no stipulations on winemaking or maturation

89
Q

Describe Oloroso Sherry

A
  • Oloroso Sherry have attributes from the oxidative style of sherry wine making.
  • They are fortified to 17% to stop flor development
  • Brown in color
  • Dominated by tertiary and oxidative aromas (toffee and walnut)
90
Q

How are naturally sweet sherries produced?

A
  • Once harvested, the grapes are laid out to dry in the sun for 2-3 weeks, causing water to evaporate and concentrating the sugars and causing raisin like flavors to develop
  • Fermentation stops naturally around 4-6% abv, and then are fortified to 15-16% abv
  • Usually matured oxidatively in their own solera systems where gradual evaporation concentrates the sugars and flavors
91
Q

What are the two most common grapes used to create naturally sweet sherries?

A
  • PX (Pedro Ximenez)

- Moscatel

92
Q

What is the minimum sugar level for PX sherry vs what they normally reach?

A
  • 212 g/l minimum

What is the minimum sugar level for Moscatel sherry vs what they normally reach?

A
  • 160 g/l minimum

- Usually between 325-375 g/L

94

What are the two different kinds of sweetened sherries?

A
  • Pale Cream

- Medium Pale Cream

95
Q

Are sweetened sherries ever aged in a solera?

A

Yes, it is not common but they can be

96
Q

What is used to sweeten up Pale Sherry?

A

RCGM (rectified concentrated grape must)

  • This is used so that no additional color or flavors are added to the wine.
97
Q

Are Pale Sherries aged at all prior to sweetening?

A

Pale sherries must have gone through a period of biological ageing prior to sweetening

98
Q

What the average sweetness level for Pale Sherry?

A
