Hi,

I'm just about to brew my first all grain lager. I've been researching the fermentation process. This is what I plan to do,
1. Ferment for 2-3 weeks at 15 degrees C ( I have a temp controlled fridge)
2. diacetyl rest 2-3 days (18-20 degrees)
3. Crash temp to 3 degrees and leave for 6 weeks before kegging

Do you think this looks right? Any tips or thoughts.

Also, I plan to ferment in a plastic bucket, do you think I need to change to a different bucket between stages i.e. at diacetyl rest or should I just keep in the same bucket all the way through until kegging?

1. At 15 you'll probably be done sooner. Go by the gravity.
2. Depending on the yeast a d-rest may not be necessary. I've never needed one.
3. You can keg first, then cold crash.
The more times you change buckets the more times you have to introduce oxygen or something that can cause spoilage.
