I keep hearing Lakefront popping up in conversation over and over again. I need to find a way to get a mix of six or something. BrewingTV's episode on them strongly reinforced that opinion.
I'm also a big fan of Rogue's double ipa. They make a lot of good beers. Dead Guy Ale was the one that /finally/ got my dad to appreciate hoppy beers. I don't think I've seen many (if any?) people on here say they don't like Pliny; that beer is real close to the pinacle of the style.
Sierra Nevada, though...unfortunately, I can't say I've had any of their beers that I've ever liked. I know they're a big name on the craft front and been around a long time, but nothing about any of the SN beers I've tried has impressed me enough to make sense of how often I see the name come up. Is there something about them I'm just not seeing or tasting?
