Sorry for asking another dumb question, but I was wondering whether it's possible to use 2 different yeast strains in one beer? For instance, a packet of dry along with a vial of liquid? Because my brewing is spaced out and my resources are limited, I'm not cleaning and re-pitching any yeast, so dry is a much less expensive option. Using the pitch rate calculator, I'd be looking at $25 for yeast alone if I go the Wyeast or White Labs route. I've had good results with the dry yeast though, so I guess if it ain't broke there's no need to fix it, right?
