Sierra Nevada Brewing Company

A very nice brewery in a beautiful setting (think mountains, forests, patios, courtyards, fire pits, and stages for live music). You can get a beer from the bar and stroll around, or you can buy one from the gift shop for 1/4 the price and crack that bad boy instead. There is also a full service restaurant.

You can do a self guided tour (for free!) and walk around the brewery looking at display cases of historical beer stuff, and look down through windows at all the production-y things happening below. A very good option if you don't want to pay for the tour and spend 90 minutes of your time learning about how they put way too many hops (for my liking) into every single beer that they make...
