Q

WHAT IS THE EFFECT OF DELESTAGE?

A

Delestage means the process of fermenting red wine with skins and seeds, and doing sub-heroic treatments to the fermenting mass to insure not only a complete fermentation, but to achieve a finished wine with good fruit, soft tannins and stable color.

Q

WHAT IS MÉTAYAGE?

A

Métayage– The cultivation of land for a proprietor by one who receives a proportion of the produce. This is a kind of sharecropping mainly done in Burgundy. This system of of land rental is where rent is paid to landlord in agreed proportion of grapes and not cash.

Q

WHAT IS SÉLECTION MASSALE?

Q

WHAT IS MACÉRATION CARBONIQUE?

A

Macération carbonique - Red wine making process which transforms a small amount of sugar to ethanol, without the intervention of yeasts, and without crushing the grapes creating a intracellular fermentation. Carbonic Maceration must also include a standard fermentation as the berries cannot produce more then a couple of degrees of alcohol and the sugars are never fully fermented dry.
