Hello, I did my first BIAB yesterday and am getting a little confused about the water quantity. I ended up with what looks like a 62.3% efficiency.
I wanted to make a 20L batch
I had a recipe which said I needed 25.88L in the boil to be left with 21.88 for fermentation. I mashed with 24L and intended to sparge with 7 based on the predicted 15% boil off rate.
I have ended up with 23.5L in my fermentation pot (planned for 21.9). I actually got just over 5% for the boil rate so had more water than planned, Because of this I only sparged with 5L in the end instead of the 7 I'd put on the recipe.
This was still too much as I'm way over. The recipe from brewfather says to get these volumes with the 15% boil off I had, I need this water, but it didn't work out like that on the day!
Anyone able to point out what I'm doing wrong?
Please let me know if more information is needed
