Fermentation & Still Wine Production Flashcards
A standard size (60 gallon/225 liter) oak barrel
Barrique
Letting the newly pressed juice settle for a day or two before fermentation is allowed to begin
Debourbage
Adding sugar to the must before fermentation begins
Chapatalization
Allowing the wine to rest on the dead yeast cells after fermentation has completed
Sur Lie Aging
The stirring up of the dead yeast cells back into the liquid
Bâtonnage
Grape juice, or the mixture of grape juice, seeds, and skins that will be fermented and transformed into wine
Must
A chemical by-product of malolactic fermentation that imparts a buttery aroma to wine
Diacetyl
An enzymatic fermentation that occurs in the absence of oxygen within whole, unbroken grapes
Carbonic maceration
Considered to be the highest-quality juice in the batch
