How is alcohol-free beer manufactured? Can one make it at home?
The only way to make non-alcoholic beer that actually still tastes good is to boil the alcohol off under a vacuum. Since the vapor pressure of alcohol is much lower than that of water, they can ...

How to know if kombucha is alcoholic?
The problem is that the hydrometer is used the amount of sugar in the solution, not the amount of alcohol. So you can measure the original gravity (OG), and the final gravity (FG), but in kombucha the ...

How much will initial oxygen in wort affect final alcohol in beer?
"This means that the initial metabolism will be aerobic. Aerobic metabolism of sugar yields no alcohol, but still reduces the gravity."
Well, actually this isn't true in virtually all fermentation ...

Where does the ABV% "magic number" come from?
131.25 is to calc ABV (Alcohol by Volume)
105 is to calc calculate ABW (Alcohol by Weight)
((OG - FG) * 105) * 1.25 = ABV
So:
(OG - FG) * 131.25 = ABV
These formulas are flawed in that they get ...

when does the alcoholic fermentation end?
CO2 in suspension will cause bubbles to come out of the airlock long after the fermentation is done. It is an indicator, but not a precise one.

How to predict ABV in cider?
you can predict ABV by using the yield calculation, Safcider gives 1% of ABV for 16.3g/l
1049 ~ 135 g/l
therefore
135/16.3 => 8.2% ABV
Or you can get more complex by looking through these ...
