I was just there last week while visiting family in SD. Nice taproom and it was fun to do a side-by-side of similar beers brewed with different strains. Made me appreciate how something even as simple as a hefeweizen can vary in flavor due to differences in yeast.
How fun! It never occurred to me that White Labs would have a tour and tasting room. It's good to know that there's enough interest/volume to support the existence of both.
