I just followed the decoctions that beersmith suggested and adjusted my protein rest temp to 55 after reading up a bit about it.
Ended up more of a Marzen, ahh well, its now at 10 degrees and my starter is ready to be crash chilled, bit sad though after being so used to grain to brain in 7 days having to wait months to drink this.


This video explains it the best imho

Pictures worth a thousand words.

Someone posted this ages ago, the decoction mash starts around 2 minutes into the video:

Brewery in Germany in the 1930s

If you know a little bit of German and can decipher the old gothic blackletter fonts it's amazing that most of their brewing terms are virtually identical to ours.
