SPARKLING WINE Flashcards
What type of climate is best suited for sparkling wines? Why?
In cool climates, grapes with high levels of acidity work well in sparkling wines. Styles are refreshing and light
What do some regions do to assist with retaining acidity in sparkling wine production?
Pick the grapes early in hotter climates, such as in cava production in Spain.
What are the 6 methods of making sparkling wine?
- T.M
- Tank method
- Asti method
- Injection method
- Ancestral method
- Transfer method
How are sparkling wine grapes traditionally handled? Why this method?
Hand-picked in whole bunches. Whole bunch fermented to reduce contact with grape must and skins (especially for black grapes).
How is grape must taken from grapes in sparkling wine production?
a gentle press is done to prevent extraction of colour and tannin.
How is the traditional method done? What are the 7 steps.
- Make a dry still base wine
- Blending
- Secondary fermentation
- Autolysis
- Riddling
- Disgorgement and corking
- Bottle aging
Describe step 1 in Traditional Method production.
A dry base wine is made to 10-11%ABV, usually done in stainless steel to promote fresh fruit flavours.
Why is a reserve stored and used?
Brand consistency, Used when vintage variation is large, flavour and complexity
Describe step 2 in traditional method production.
Blending. done to blend different grapes, different vintages or different grapes from plots of land to achieve complexity, consistency or balance.
Describe step 3 in traditional method production.
In secondary fermentation, a mixture of wine, sugar, yeasts, nutrients and clarifying agents is added to the wine to continue fermentation to gain another 1.2-1.3%ABV
What is the addition of yeasts, nutrients, sugars, and clarifying agents called in secondary fermentation?
Liqueur de Tirage
What does liqueur de tirage raise the ABV?
1.2-1.3%
How many atmospheres of pressure are gained during Autolysis
5 to 6
What is the traditional a frame rack called for riddling?
Pupitre
What is the riddling machine called?
Gyropalette
What is the addition of wine and sugar during disgorgement and corking called?
Liqueur d’expidition or dosage
What is the transfer method?
An adaptation of the T.M in which once autolysis flavours are achieved, wine is transferred into a tank
What is the ancestral method?
single fermentation by fermenting in the bottle
What is the sugar per litre for Brut Nature?
0-3g/l
What is the sugar per litre for brut?
0-12g/l
what is the sugar per litre for demi-sec?
32-50G/L
