Sparkling Wine Flashcards
What is the ideal climate for grapes
Cool climate
How does the climate affect the grapes when growing?
Cool climate; to allow sugar and acid to increase slowly for correct levels
What levels should the sugar be in the grapes?
Should be low: base wine 10-11%abv, as second ferm that gives bubbles will increase alc by 1.2-1.2%abv;
What level should acidity be in the grapes?
High; many are made in a refreshing styles
What flavour characteristics should the grapes have?
Ripeness in flavours, no longer green herbaceous flavours
How are the grapes traditionally picked and why?
Hand picked; to keep whole bunches
How might the grapes be picked in warm climates and why?
Where grapes grown for inexpensive SP’s, machine harvesting may be the most efficient way b/f they accumulate too much sugar and lose acidity.
When should the grapes be pressed?
As soon as possible once arrived at the winery
What are pressing considerations?
Gentle to minimise extraction of tannins or colour
Why is gentle pressing of grapes important for black varieties
Especially important if using in white sparkling’s; use of whole bunches helps by avoiding crushing so that contact between skins and juice is minimised
EU region legislation determines what?
In most EU regions legislation determines the maximum pressure that can be used during pressing and the amount of juice that can be extracted from the grapes
What are the 7 Principle steps of the Traditional Method?
- Making the base wine
- Blending
- Second alcoholic fermentation
- Yeast autolysis
- Riddling
- Disgorgement and corking
- Bottle ageing
Where does the first alcoholic fermentation take place?
Large, temperature controlled stainless steel vat;
some still use oak vats/barrels
What should the base wine be like?
Completely dry, neutral flavours, high acidity
What decision will the winemaker make before the 2nd fermentation?
Whether or not to use MLF or oak maturation
When are most base wines used?
In the year after harvest
But some wines are stored for use in future years;
these ‘reserve’ wines are important for blending process
What can help improve the balance of a wine?
Blending
What can help enhance the complexity of a wine
Blending
What can blending from different vineyards/vintages/varieties do?
Can help keep house styles consistent yearly despite vintage variations
What can help bring texture and/or spice flavours to a wine?
Blending with wines matured in oak
How can winemakers make it easier to achieve aims?
Having many base wines available to them; thus grapes often fermented in small parcels to allow for multiple blending options
When is liqueur de tirage added?
Once the blend is made up, small amount added
