![]() ![]() You may have had phenomenal efficiency or you may have added and recovered less wort than the program called for. Without a volume figure to match up with this value, there is no way to determine exactly what your mash/lauter efficiency was. Your pre-boil gravity was 1.071 as you entered it. The boxes are still yellow, which means that no user measured value was entered.Ģ. You did not fill in the measured post mash gravity nor the measured pre-boil volume. OK, let me tell you what I see here in your recipe.ġ. I used them to help set up my BIAB profile. 5 gallon trub loss.Īnd thanks Kevin, I've seen those vids on Brulosophy. I've attached recipe again, accounting for the. 5 gallon trub loss, but that's still low for an estimated OG of 1.081. I know it's because of the larger grain bill, I just want to know why BS estimates my pre boil at 1.058. I've had to manually adjust the BH efficiency to get better estimates (after the boil and reading the OG), which has worked until this beer. Beersmith also does not estimate BH efficiency. My preboil volume was 7 gallons and my post boil was 5.5, which is what my equipment profile says. I had roughly another 1/4-1/2 gallon or so that I just didn't add. ![]() I just used a much bigger grain bill this time, and I know my efficiency suffered. This was my 4th BIAB, and I've hit all my number so far. I didn't add any extra, so I don't know why my est pre boil gravity was so much higher than estimated. I cannot change post mash gravity (Beersmith won't let me, and it estimates it automatically), which should equal est pre boil gravity if no more sugar is added. But there has to be something I'm missing.Īll the volumes that I can manually record are recorded. I've been working on tweaking my equipment profile to make it as accurate as possible. ![]() I'm not sure what you're seeing in my equipment profile, but everything seems ok on my end. It can take many brew sessions to dial it all in. ![]() The bottom line is to just make sure your measurements are accurate and incorporated into the equipment profile. Just adding 0.5 gallons of trub loss, plus making the post mash gravity and preboil volume correct, raise the estimated brewhouse efficiency to just under 64%, much closer to what you seem to have achieved. Although the batch size is 5 gallons, the estimated post boil volume is 5.5 gallons there. The equipment profile has no losses for trub. Adjusting preboil volume for this gives mash efficiency at 64.7%, much better than the 58% BeerSmith estimated. If you had 1.080 at 5 gallons post boil, then you should have had 6.35 gallons preboil at 1.071. You recorded 5 gallons both pre and post boil, but your profile expects 1.5 gallons of boiloff to concentrate the wort. The volumes you recorded don't match what your equipment profile expects. If that's brought up to 1.071, your mash efficiency is 71%. The mash efficiency is calculated from the post mash number you fill in. You have a preboil gravity recorded as 1.071, but post mash is only 1.058? BeerSmith expects the difference to be from kettle sugars and your recipe has none. This is hard to diagnose because it seems like the session data is incomplete. ![]()
