"We only do what the grapes allow"
During winemaking, several processes follow one another depending on the wines we produce.
The goal of winemaking is to transform grape juice (sweet, fragrant, sour, bitter and tannic) into wine. A fruity, alcoholic wine, more or less coloured and more or less tannic.
It is therefore important to know the main components of the grapes which will give the characteristics of the wines that we want.
