how early is too early!

Wed Mar 16, 2016 2:19 pm

I brewed an Alt 10 days ago (OG 1.060). I added oxygen and pitched a pretty big starter. I think it was done in 2 days. I pitched at 60F and after 5 days brought it up 2 degrees. 2 days later I brought it up to 64F. I plan on letting this sit for at least a month after kegging and carbing. Is it too early get this sucker into kegs? I don't filter but I do use gelatin to help clarify. Should I bring it up a little higher temp wise before kegging to help reduce diacetyl?

I would do a heated diacetyl test to see if there is any diacetyl left in the beer. Heat a sample of it up to 150F or so for 10-15 minutes (I use the microwave and just keep hitting it with 30 second bursts now and then), then let it cool and compare it to a non-heated sample. If there is diacetyl or precursor in there, it will be evident and you should leave it on the yeast a little longer.

If that comes up clean, and the flavor doesn't have any green apple in it and the gravity is stable, then keg it.

I am a big fan of letting most average gravity beers (1.050-1.060) sit in primary on the yeast cake for at least 12-13 days at room temps (68-70F) prior to cold crashing overnight and then kegging on day 14. I feel that it is just extra assurance that the yeast will fully clean up after themselves without me having to do any extra work.

+1. My ale brews almost always go 14 days in the FC. Even when they seem to finish early I keep them on the yeast until then. When in doubt I go with negative or static pressure through the air lock or blowout tube for a period of 5 minutes (as long as the system is gas tight). For diacetyl rest, as in Irish Red Ale, the same practice applies, but maybe add three days.

Thank youz, gentlemen. It's still in the fermenter as I haven't had the time to keg it up. Being patient has always worked best for me in the past. However, I did get a little excited to free up fermenter space so I could brew my next batch. I hope to brew again in the next couple of weeks.
