how much alcohol is needed to preserve wine
To get around these nasty but accurate equations simpler equations have been developed but they are only relevant for a small range of alcohol content. Wine, typically has an alcohol content of around 11-15% while beer is usually around 5-6%. Because of this they each have their own alcohol content equation based on these different ranges of alcohol. In short be sure that youâre using an equation specific to wine making. A beer equation can lead to incorrect results. The Wine Alcohol Content Calculator. The simplest way to calculate your alcohol content is with a calculator. Youâll need to know your starting or original specific gravity that you took before fermentation began. Also, youâll need the final specific gravity taken once your wine has finished fermenting and is stable.
