Hi team,
I'm hoping you can help me with some issues I am having nailing down my efficiency in relation to boil off, losses & BH efficiency. There's a few questions that I have & I will try to be as succinct as possible, but if you need any further information please ask.
My issue is that my expected OG is higher than what I am getting. When I first started using the software I had not entered my losses, so effectively BH & mash efficiency were the same. I was often mashing in the mid 70% efficiency, but then BS would predict a 10-15 point gain during a 60 minute boil off and I was only seeing a 5-6 point gain.
This caused me to properly go through all my processes & work out what was going on. I am now confident, that my equipment profile is dialed in, but I'm still getting incorrect data. I have done a boil off experiment to confirm that my boil off rate is 3L per hour. I have also previously measured my kettle trub to 1L. This has been entered in as well.
Based on this data on a recent recipe, Beersmith (with 70% BH efficiency & 74.8% mash efficiency) expects the following;
Pre boil gravity - 1.048
Post boil gravity - 1.063
My actuals were:
Pre boil gravity - 1.048
Post boil gravity - 1.054
So I hit the mash efficiency as usual, but way off on the OG. If I wanted to match the OG in BS I would need to drop the BH efficiency down to 64% with a predicted mash efficiency of 68% & pre-boil gravity of 1.041, which is way under what I got.
What am I missing here? With the information I have, ie boil off rate, pre-boil gravity & post boil gravity & pre & post boil volume, what is the easiest way for me to dial in this equipment profile? I want to clarify, I'm not that concerned with chasing numbers, I just want to be able to rely on this software to properly predict the outcomes.
Appreciate your help!
