I think Oberon is one of the best summer beers out there!
Has anyone ever made a business of taking commercial beers and selling yeast? Is it legal? If so, I think there would be a market. Yeah, I know that you can do it yourself, but for those who don't have access to certain beers, it would give us an option to clone.
I don't know, Bells is pretty quick to sue over infringements. Look at northern brewers Dead Ringer IPA. It sued to be called something like three hearted or something like that. There have been several other court cases with Bells.
