Yooper - I don't have the abilities to lager yet. I have been doing 10 gallon ale extract batches. Kegging half and bottling half. I know Dos Equis is a lager, just trying to venture out a little and try something other than a kit.
What type of Munton DME? I usually get my stuff from midwest. They list everything from extra light to extra dark.
Have you ever tried liquid wyeast? For this I was thinking American Ale yeast 1056.
