Us05 And Diacetyl

[Maxt]

To add to my us05 lessons; this yeast takes longer to clear acetaldehyde than others I use.
Especially with dark beers, if I kegged after a week at terminal gravity, I would get a green apple beer. Now I know to leave it on the yeast for an extra 3-5 days.

I use US-05 exclusively and get butter if I dont let the brew come up to 22 or so for a day or two at the end of ferment.
