I am thinking my next brew is going to be Tasty McDole's Janet's Brown Ale from Brewing Classic Styles. In the book they recommend 7 gallon boil, with 6 gallons post-boil and 5.5 gallons going into fermenter and 5 gallons left for bottling.
The question I have is in BeerSmith recipe builder, the batch size is suppose to be the estimated amount into the fermenter, or in this case 5.5 gallons. But when I enter that and then the ingredients at 70% eff (per the book), BeerSmith has OG of 1.073 vs 1.066 per recipe.
To hit the target gravity I need to change my batch size to 6 gallons. But won't that throw off brewhouse efficiency numbers because now BeerSmith thinks 6 g will be going into fermenter but actual will be, per recipe, 5.5? This one has me stumped!
