Priming Sugar increasing abv?

[Joshua542]

This seems to me like a stupid question, but I'm still curious. Does adding priming sugar and then bottling produce any extra measurable alcohol in the beer over the next 1-2 months in bottles? Considering it is producing CO2 it must procing alcohol, but how much?

Here is something I read before regarding your question, and a ball park estimate is around .3% to .5%. It will depend on the batch size, type of sugar and amount used.

I always wondered about this myself. I assumed the yeast would produce more booze since they're eating sugar to produce the carbonation. I always added an extra 2-3% based on the co2 level of the beer I was going for.

NTXB is right. with the calculators I've seen or used,it's .3 to .5% on average. It depends on which formula you use. I've seen like 8 different ones & the results are all different. Cooper's ABV formula gives the highest number,but still within range given by Beersmith2.
