How mayny teaspoons of sugar are in a glass of white wine?
Wine comes from fermenting sugar from grape juice. The sugar
content at harvest will determine the potential alcohol of the
wine, normally recorded in Brix. The easiest way to determine how
much sugar,residual sugar, is left in wine is to calculate the
difference of potential alcohol before fermentation and after
fermentation. The remaining sugar left unfermented will be the
sugar left over in the wine (white or red). Thus, each wine will
have a different amount of 'sugar' left depending on winemaking
practice and style.
It is possible to test the wine for residual sugar, but I feel
this question assumes that all white wine has the same amount of
sugar; this is incorrect, so this question is too vague to
answer.
