Can't really say about components but grapes with more sugars means potentially more alcohol levels of wine if the yeast can ferment to dryness.
A higher level of alcohol can be achieved by having more sugar in the grapes. Some winemakers actually stop fermentation early to leave some residual sugars and sweetness. Yum!
I don't do Alcohol because of my religious beliefs.Sobriety Sounds neat, so you would not have any measurable alcohol levels or effects from it. Yeah exactly, what can you tell me about alcohol anyway? Alcohol would be a psychoactive substance that can be found as an active ingredient for alcoholic drinks like wine or beer or distilled spirits. Its chemical name would be ethanol. You mean ethanol is the reason why one gets drunk? Not sure about that although it is taken as a popular recreational drug. So what other components of a strong wine apart from the ones mentioned?
The more sugars in the grapes, the higher the potential alcohol level of the wine if the yeast are allowed to carry out fermentation to dryness.
