I've done that!
I'm on the fence about my urquell slurry. I'll keg the pilsner next week or so. Decide after a gravity check on the pils whether to keep it and how much.
Just did a 1L starter of Bavarian Lager yeast that I'll likely use for some undetermined lager in the next few days. I'm thinking about a vienna and maybe 5 gals of munich lager or a boch or something a little bigger. I'm just not into heavy and malty at all right now so I can't seem to get out of the pilsner/IPA rut I've been in. I'm happy with the beers but kinda bored brewing the same stuff over and over.
