Otter Creek has a solid tour. They might not have the most exciting beer in the world, but it's unlimited tasting before and after the tour. If it's not on tap, they'll walk in to the cooler and crack a bottle and pour you a sample. The tour itself takes you all over the brew floor (following the brewing process of their flagship Copper Ale). They open up the kettles. I could have spit in the whirlpool. I was told if the timing is right, they even let tour participants throw some hop addition is. Pretty sweet in my book.
