Mash Efficiency

[cowboy7307]

if i look at a recipe and its efficiency says 80%
and i am doing BIAB and i think my efficiency is say 65%
how do i adjust the recipe to suit BIAB

Under Profile > Edit > General, set your preferred Method to BIAB.

For each Equipment Profile, you can set the Average Efficiency.

You can also change these in the recipe editor directly, but setting them in those places first will default a new recipe to use your own numbers and method.

65% is a bit low for that method though. Be sure to research the BF article on efficiency calculations, and be sure to meticulously measure all of your volumes and losses for several batches. (do not estimate - measure.) After about 5 or so batches, you should have a good running average for efficiency that will stabilize. Also, be certain you are mashing to complete 100% conversion, not just by time. (use an iodine test if you can) The efficiency article will show why that is important. If you are inconsistent with mashing to full conversion, your efficiency will be all over the map.

Yeah
That's a problem with copying recipes
That don't give the efficiency
Put the recipe in the recipe builder and also their efficiency then in the tools section you can see scale by efficiency

That’s a solid way to use the BF Recipe Builder. Once you’ve set your brewing method (BIAB) plus brewhouse efficiency and switched the target mode to Goal: O.G., you can basically “reverse‑engineer” the recipe. Enter each fermentable with its exact weight, and the builder will immediately show how far above or below the target gravity you are. From there it’s just a matter of nudging the grain amounts until the projected O.G. lines up with the goal. It’s a nice, visual way to sanity‑check a recipe and make sure the numbers actually match the intended gravity. This works for hop additions and target IBU.

Cheers!

Never had allot of luck doing it that way. Too many variables that cause efficiency to change.

Easiest way i have found:

Mash
Boil
Take SG reading.
Add water to make SG what you wanted
Ferment

Your volume will vary, but the beer comes out right every time

I'll be honest, I dont take readings anymore or worry about gravity but I was obsessed years ago so go for it, my final word is it usually tasted good and that's all that matters
