At the end of the day whatever I formulate goes onto a brew day spreadsheet with a "Suspected yield" of my target kettle volume. I try to base all my numbers on kettle volume though. Now I have Beersmith and some good numbers on my efficiency. I used Brewtarget for a while but it's basically broken for whirlpool IBUs, although it was good for getting me close or doing porters/ales without many knockout IBUS (Once I got my efficiency numbers). The little electric has a more vigorous boil so I find my knock out/whrilpool IBUs a bit hard to scale.
Efficiency went from 65% to 94% so I lost a lot of color. I went from 1.5 BBL Electric to 10 BBL Steam with no software.
Once a recipe is in Brewers Friend we can re-brew pretty simply. While there is lots of paid programs out there and I really like the Beersmith style guidelines and ease of recipe creation- we use Brewer's Friend (online) on Chromebooks in the brewery to log and track the brews. Our efficiencies were fine UP TO knockout and transfer. We thought our mill and mash SOP was terrible only to find out the whirlpool design on the boil kettle leaves more wort behind than we calculated. Total Brewhouse Efficiency is wildly dictated by how efficient the tank design and if you can accurately calculate final volume into the fermenter. Mash conversion and pre-boil are so important in assessing mill settings and mash SOP but it's not easy in Beersmith. You have mash conversion efficiency, pre-boil efficiency, post boil efficiency and finally total Brewhouse Efficiency (final gravity and total volume in the fermenter). My complaint with Beersmith is in calculating Brewhouse Efficiency.
