Etc Flashcards
In the winemaking process for white wines, once the grapes have been pressed but before the must begins to ferment, we need to separate the clear, transparent must from the solid particles suspended in it.
Debourbage or settling
The process of earthing up the bases of the vines to protect them against frost.
Buttage
Passerilage
Drying grapes after picking
French term for racking
Soutirage
traditionally the wine is ‘racked’ or drawn from barrel or tank to another empty one on a number of occasions (called soutirage). This helps clarify and freshen the wine by removing the fine lees or sediment which forms and provides a tiny amount of oxygen to help the aging process
traditional method in wine production of moving wine from one barrel to another using gravity rather than a pump.
This process softens tannins, clarifies the wine and enhances aromatic qualities.

List the fining agents
Gelatine. Isinglass. Egg white (egg albumen) Casein. Skim milk. Bentonite. Carbon (charcoal) Polyvinylpolypyrrolidone (PVPP)
What is muttage
the addition of alcohol to the must so that the fermentation process is prematurely stopped. Most yeasts die when the alcohol content in their environment is raised to approximately 13–15%.
What is bentonite?
Fining agent - Aluminum silicate clay
Using an excess of bentonite removes color and aroma and may leave some off-odors.
What is activated Carbon?
This fining agent is used to reduce color intensity and to remove bad odors from wine. In white wine, it reduces the oxidized brown or yellow color or the pink color in ‘blanc de noir’ wine.
Due to its absorption capability, carbon will also absorb aroma and flavor component, reducing the concentration in the wine, and hence should be used only if no other means is possible to fix the problem .
What is Gelatin?
Finning agent used to reduce tannin levels in whites or red wines. In whites, it may also reduce the bitter after taste and may lower the astringency of young and overly tannic wine.
Gelatin is a protein obtained by boiling skin, tendons, ligaments, and/or bones with water.
One of the best fining agents for red wines?
Egg whites. This is considered one of the best fining agents for red wines. Its purpose is to soften the wine’s astringency and to mellow its feeling with no after effects.
What is PVPP
short for polyvinylpolypyrrolidone, this is a synthetic polyamide polymer which is insoluble in water and doesn’t leave an off flavor in the wine.
Vegan fining agents?
Carbon, bentonite clay, limestone, kaolin clay, plant casein, silica gel, and vegetable plaques
What is isinglass
very pure gelatin prepared from the air bladders of fishes (such as sturgeons) and used especially as a clarifying agent
