I have an equipment profile I have dialed in for 18 gallon batches and a brewhouse efficiency of 81%. Based on those settings I pretty consistently hit the estimated gravities and volumes that BS calculates for me when brewing batches from 18-25 gallons. However I recently added a recipe for a much smaller 7 gallon batch based on ingredient percentages (70% pale malt, 10% crystal 20, etc.). Once I input all the ingredients with the proper percentages using my equipment profile, which has a batch size of 18 gallons, I noticed the estimated mash efficiency is 104%. The BH efficiency in the recipe is 81% as expected. My equipment is the same with the usual losses in the chiller, lines, fermenter, etc. regardless of batch size. I'm just making a smaller batch using those loss volumes. I'm just concerned with the estimated mash efficiency being >100% and not in the range of 89% that I normally see with other large batches. Can someone please explain what is going on? Should I have added the ingredients for the recipe for an 18 gallon batch and then scaled down, or should I have a separate equipment profile for smaller batches and build small recipes using that profile?
