Thank you for all your replies and suggestions.

My OG: was 1.090 and today ( after 11 days SG: 1.030) which places me at 67% attenuation.

I will take it out of the freezer and will let it rise to 60F (temp in my basement) over the next few days for the diacetyl rest. I am planning on leaving it out for 3-4 days.  After that I am planning on transferring it to secondary and lager.

Should I raise the temp higher then 60F ?

I was planning to drop temp to 40 and lager for another 2 months. Should I do it differently?

Thank you.

Subject: Re: [mba] lagerng and diacetyl rest

We've used 833 for years (currently have an 833 Ofest kegged up, and an 833 Dunkel in the primary). We've never done, nor needed a diacetyl rest. If you're having a problem with diacetyl in your lagers, then you're not fermenting them long enough (or not pitching enough yeast, or haven't oxygenated your cooled wort. BTW, we only oxygenate on the first generation fermentation. If we're making another beer style on the lees from a previous fermentation, we don't oxygenate.)

A week at 52F for a first generation fermentation seems a little quick to me (assuming standard 1.048-1.052 OG) for WLP833 (German Bock -- Ayinger). Give it another week or two (depending on actual OG). It'll be fine.

Alexey-

Are you asking if you should raise the temp of your starter for a diacetyl rest? I make my starters at pitching temp and have never done a rest and never suffered poor results.

Hello Ladies and Gentlemen.

I am in the process of making a doppelbock and have a quick question.

I am using WLP833 yeast (made a yeast starter and oxygenated for about a minute or so). It is fermenting at 52F for 7 days now.

How would I know when to  increase temp for the diacetyl rest?

I am planning to take it out of freezer and let it sit in my basement (60F ) for about 3 days. (Please suggest if I should be doing something else).

 

Thank you.
