Sparkling Flashcards
Chardonnay’s susceptibilities
Early budding so prone to spring frosts
Coulure and millerandage
More disease resistant that PN but still susceptible to powdery mildew, grapevine yellows and BBR
Pinot Noir susceptibility
Early budding so spring frosts
Coulure
Thin skinned so disease prone, especially downy mildew but also powdery, BBR, fan leaf and leafroll virus
Laccase’s effect on the wine
(Enzyme released by botrytis affected grapes)
Serious oxidation
Standard fermentation temperature for sparkling wines
14-20d celsius, typical to retain fruit but not too cold for the yeast
Liqueur de tirage contents
Wine +/ must, sugar, cultured yeasts, yeast nutrients and a clarifying agent eg bentonite +/ alginite (seaweed extract to facilitate riddling)
Amount of sucrose added in liqueur de tirage for fully spk wines
24g/L, = +1.5% alcohol
Conditions yeasts need to be able to withstand for 2nd fermentation
9.5-11% abv
Temps of around 16 degrees
pH values below 3
Later withstanding increasing pressure in the bottle
Temperature bottles are stored at for 2nd ferm
10-12 degrees
Maillard reaction
A process in which sugar in the liqueur d’Expedition reacts with compounds formed in yeast autolysis and causes the development of roasted, toasted vanilla aromas
Other names for tank method (3)
Cuve Close, Charmat and Martinotti
1st Fermentation temperature for tank method and why
16-18 degrees to retain fresh fruity and floral notes but avoids flavours associated with low fermentation temperatures
Diameter of cork before bottling for sparkling
31mm
Inside bottle neck diameter, and percentage it allows the cork to expand back to
18-21mm, to 60-70% original width
Dom Pierre Perignons contributions to Champagne
Produced first white wine from black grapes.
Invented the still widely used coquard press.
Blending wines from across the region to make a superior wine.
Thought to have introduced the cork stopper to France.
Pioneered the use of English glass.
19th century developments in Champagne
2nd fermentation in the bottle with measured yeast + sugar to produce a known pressure.
Madame Veuve developed riddling using pupitres.
These enabled disgorgement to be developed in the last quarter of the century resulting in a dry style of Champagne.
The year vineyard area and AOC of Champagne was set
1927
