Not always, but usually. There's a few breweries that I'll try anything from blindly (Troegs, Bells, Founders, Victory). It helps having a smartphone though. As others said though, I look less at the rating and more at the descriptions, and I never take "The Bros" rating into account. I used to pay attention to ratings more, which led me to having left over Duchesse De Bourgogne that I can't stomach, and drainpouring a few saisons and berliners (sorry, robinsmv).
