Production of red wine is slightly different than the process of
making white wine. Red wine is fermented at warmer temperatures
than white wine. For red wine production, the skins are fermented
with the crushed juice
As long it is a dry wine, both red and white
wine contains little amounts of sugar. On average dry red or white
wine will have around 1 to 3 grams of sugar per litre of wine.
