So other than keeping with tradition, why do I want to use a brit ale yeast to make a stout? or a California ale yeast for an APA? I'm just curious how many of you have made a certain style of beer with a non-traditional yeast? I'm thinking I want to experiment a little using the WLP001 yeast cake I have from an APA to do a Cream Stout. I know it sounds weird, but are there any major flavor differences I should expect? Thanks!
