Timing for diacetyl rest?

[Kenthebrewer888]

Hello I need help . I try to find out when to do the diacetyl rest . I keep reading it at 2/3 or 70% or 2 to 5 points above your FG I am just confuse .

Welcome-

Look at the OG and expected FG of your recipe.
subtract them
add 1/3 of that and round up to the FG

When your beer gets down to that gravity, its time to crank it up.

Example:

OG = 1.050
FG = 1.012

difference = .038
.38/3 = ~ .013

1.012 + .013 = 1.025

at 1.025 crank up the temp to around 65-70F and let the yeast go nuts until you don't smell/taste diacetyl any more.
Then, lower the temp about 2 degrees a day until you get it down to 33F for lagering.

Good luck!
