Hey I;ve been using the Brewers friend tool for about 2 years for all grain and it's great! There is something that has perplexed me though; What is the most reliable way to calculate ABV after bottling/priming? I usually estimate approx. +0.3% for 2 volumes CO2. It would be great to incorporate a reliable tool that gives final (bottled) ABV as a function of the bottling/priming calculator. Obviously this would vary dependent on the priming rate/sugar(attenuation) and possibly the current FG/ABV before bottling.
