Sparkling wines Flashcards
How are the requirements for growing grapes different for sparkling wines than they are for still?
1) Grapes should be relatively low in sugar 2) High acid levels are desired 3) even though the grapes are low in sugar and high in acid they still need ripe flavors so they do not have green herbaceous flavors
What type of climate do you need to grow grapes for sparkling wine? And why?
Cool climate. The changes to the sugar and acid happen slowly and at the same time as the changes to grapes flavors, in warm climates the sugar rises and acid drops fast and only option is to pick early and have green flavors
What gives sparkling wines their bubbles?
The second fermentation and also increases the alcohol levels
Are sparkling wine grapes hand or machine harvested?
Premium wines are hand harvested, high volume are machine harvested to pick before sugar rises and lose acid
How is pressing and crushing handled during the making of sparkling wine?
Pressing is immediate and gentle to avoid extraction of tannins or colors and crushing is avoided to minimize contact between skins and juice
What are the five methods to produce a sparkling wine?
Traditional method, Transfer method, Tank Method, Asti Method and Carbonation method
Do laws govern which method is used to make sparkling?
In Europe local laws may govern, outside of Europe the decision is made base on desired style or quality
Which technique is most often used to make premium sparkling wine?``
Traditional
What does the term traditional method indicate?
That the wine has undergone a secondary fermentation in the bottle in which it is sold.
What are the principal steps in the traditional method?
Making the base wine, blending, second alcoholic fermentation, yeast autolysis, riddling, disgorgement and corking, and bottle ageing.
When making the base wine in the traditional method, is the wine made in large temp controlled vats or oak vats or barrels?
Both, depends on winemaker
What are 3 reasons blending is important in the making of sparkling wines?
helps achieve consistency of house style, improves the balance, enhances the complexity of the wine
What does Chardonnay bring to sparkling and what does Pinot bring to Sparkling?
Chardonnay brings citrus fruit, finesse and longevity, Pinot Noir brings body, structure and aromas and flavors of red fruit
What do sparkling winemakers do to increase their options of blending in the making of sparkling wine?
they often ferment in many different small parcels to give multiple blending options
Blending in wines for sparkling that have matured in oak can bring what?
broader texture and spicier flavors to the wine
What is the liquer de tirage?
Mixture of wine, sugar, yeast, yeast nutrients and clarifying agent. Added to bottle of wine to create secondary fermentation
What is yeast autolysis?
After the secondary fermentation is complete the yeast die and form a sediment of lees on the bottom of the bottle. Over a period of months they start to break down and release chemical compounds into the wine.
What flavors does yeast autolysis give to wine?
Bread, biscuit and toasty notes
How long can yeast autolysis last?
Between four and five years but has been known to last ten.
After the period of maturation, what do you do to remove the lees sediment from the wine?
Riddling and disgorgement
What is riddling?
Involves moving the bottle very slowly from horizontal position to an inverted vertical position. The yeast sediment is dislodged and slides down to neck of bottle.
What is the old time rack called that was used to riddle by hand?
Pupitre
What is the machine used today to riddle?
Gyropalette (holds 500 bottles on hydraulic arm)
How does disgorgement work?
Once riddling is complete the neck of the bottle is submerged in a brine solution that freezes the wine in the neck. The crown cap is removed and the pressure built up in the bottle from the CO2 ejects the frozen wine sediment.
How does corking work after disgorgement?
The wine is topped with liqueur d’expedition and sealed with a cork and a wire cage.
What is liquer d’expedition?
mixture of wine and sugar
What is the dosage?
The amount of sugar that is put into the liquer d’expedition, it determines final level of sweetness in wine.
Other than adding sweetness to the sparkling what else does dosage do?
It balances the acid and helps with flavor development.
