D4 Sparkling Wine Flashcards
Most common temperature for primary fermentation
14-20 °C
Why are buttery aromas not present after malo?
Diacetyl produced by malo is metabolized by yeast during second fermentation
French term for secondary fermentation
Prise de mousse
Parts of liqueur de tirage
wine/must sugar cultured yeast yeast nutrients clarifying agent (bentonite or alginate)
Temperature for secondary ferment
10-12°C
cooler ferment = more complexity
Length of second fermentation (traditional)
4-6 weeks
Temperature during lees ageing
around 10 °C
When is autolysis starting to be noticeable?
after 15-18 months
How long does autolysis continues
for 4-5 years on average
French name for riddling
Remuage
Explain Maillard reaction
Sugar reacts with compounds formed during yeast autolysis
roasted, toasted vanilla aromas
Explain Ancestral method
Partly fermented must is put into bottles and remaining sugar is converted into alcohol and CO2
Tank method:
1) temperature to stop fermentation
2) temperature to stabilize wine
1) 2-4°C
2) -2°C
How are wines made by tank method filled into bottles
Through counter-pressure filler
First fills bottle with CO2 under pressure. The bottle is then filled with chilled wine replacing the CO2

Factors affecting the mousse
- Amount of sugar available to be turned into alcohol and CO2
- The capacity of CO2 to be dissolved in wine (depends on grape variety and health of the grapes – botrytis reduces amount of bubble formation)
- The length of time on the lees = more lees ageing less but longer lasting bubbles
- How well the disgorgement process is carried out
- Time in the bottle and type of the closure
- The size and shape of glasses, temperature of the wine and how the wine is served
Champagne - ways to produce rosé
Rosé d’assemblage = blending red wine with white
Rosé de saignee = skin maceration of black grapes

- Côte des Bar
Montagne de Reims
- Known for black grapes (GC Mailly, Verzenay, Verzy, Ambonnay, Bouzy = on chalky soils)
- Wide plateau, top villages facing north (but more frost prone)
- Very high acidity, austere in youth
Vallée de la Marne
- Mainly Meunier on clay, marl and sand (fruity), early drinking style Chardonnay
- Frost prone valley (Meunier buds latest)
- GC Aÿ
