Notes

Uses a decoction mash to extract fermentables from the corn. No real rhyme or reason to the remaining grain bill--mostly just leftovers--but I'm pleased with the result. For enzymes I have used both Termamyl and Ceremix Flex from Novozymes, and both do the trick.

I do this one in a Grainfather so I have pretty good temperature control. It would be a lot more complicated with hot liquor infusions, but not impossible.

This is really nice stuff. Dry, with lots of berry flavor. A deep red-brown hue. The Hallertau is very present, but not unpleasantly. Might play with a different aroma hop in future versions, maybe Willamette. Great everyday ale.
