By not brewing this beer when I first posted my original article, I think I psyched myself out on the whole ‘decoction’ thing. “Single Decoction“, “Double Decoction“, “Enhanced Double Decoction“,”Hochkurz Decoction“, “Triple Decoction“, ahh!!! What have I got myself into!!
When I finally got up the courage and picked a weekend for this experiment, I had to watch and re-watch some videos on decoction mashing. Braukaiser’s video, which I had mentioned in my original post, was one I referred to a lot. I also came across a really good video on Brewing TV: Episode 34 – “Decoction Day”. In this video, Michael Dawson shows us how to do a double decoction on a Munich Dunkel. He was quite entertaining and demonstrated the steps wonderfully and clearly. So off I was to start boiling away!
Which decoction schedule did I decide to use? I decided to go with the Enhanced Double Decoction. This schedule pulls a large enough decoction from the acid rest to be able to hit the protein rest with part of the decoction, and with the remaining portion, you reach the saccrification rest. On the one side, I thought a single decoction would fail to bring out enough of the decoction character. On the other side, a traditional triple decoction really isn’t needed with today’s well modified malts, and the lengthy protein rest can actually be detrimental to head formation and mouth feel due to excessive protein breakdown. (See footnote at bottom) I modified the temperature steps slightly to hit those specified by the brewer from Pilsner Urquell in the Brewing Techniques article: The History and Brewing Methods of Pilsner Urquell.
