I'm a bit confused and I'm hoping someone can help me understand things.
I'm using BeerSmith 3. I formulate a recipe. BS3 estimates OG at 1.051 and I actually get 1.053. BS3 estimates FG at 1.009 and I actually do achieve 1.009. However, BS3 estimates 4.8% ABV, but the "% Alcohol and Attenuation" tool calculates 5.8% ABV! Even if I enter OG of 1.051 (as per the recipe estimate) BS3 "% Alcohol and Attenuation" tool calculates 5.5% ABV which is different than the recipe 4.8% ABV.
5.8% ABV is much different than 4.8%
Why is the recipe ABV (which probably everyone uses to determine grain, etc for their brew day) different than the "% Alcohol and Attenuation" tool (We will only truly know the OG and actual FG once we are done fermenting)? In other words I'd imagine 100% of the BS3 brewers rely on the recipe ABV only to discover (at bottling or kegging) the recipe ABV is wrong.
Thanks.
