Brew #65: Kölsch/Czech Pilsener hybrid

This is an experiment that I've wanted to do for a long time. The beer is a hybrid between a Kölsch and a Czech Pilsener. It is brewed with Kölsch yeast and a lot of Czech Saaz hops. There is 10% wheat in the recipe, so the fermentables are closer to a Kölsch than a Pilsener. The batch was split in half, and is fermenting with two different Kölsch strains. I look forward to seeing whether there will be any significant differences between the two strains. It will also be interesting to see if one can make a decent pilsener with an ale yeast.

Added 1ts CaCO3 (calcium carbonate) and 0.5ts CaSO4 (gypsum) to enhance the hops.

The batch was brewed 2009-01-04 and bottled 2009-01-21.

This sounds like a worthwhile experiment. Either way, it should come out quite nice. I would really like to know the outcome of it.
