I like what you've done with the bottle cap. I think it's unique and could stand on its own. I'm not sure how I feel about the corkscrew, and something about it feels too western. All in all you're definitely on the right track
#48 - Is that what you had in mind? Or did I misunderstand (which is entirely possible - I'm not even halfway through my first cup of coffee this morning :) )
Okay. Thinking about #48... Can you replace the M with something? Maybe a hop or other beer ingredient? And maybe an additional color somewhere in the logo to make it pop
#68 - here's a revised version with a hop cone - there's really just yeast & water left...which I figured wouldn't make for a great logo (unless you were specializin in BMC beers - then the water might be appropriate - haha)
