Anyone who has toured San Franciso's Anchor Brewing knows that you get to sample their beer for free and see how they make it. What you aren't allowed to see, however, is the small distillery on site. I am a big fan of Anchor's rye whiskey products, and also believe that Fritz Maytag (Anchor's owner) represents all good things in American whiskey.
Enjoy - it's absolutely worth it. And, I apologize for not being able to embed the video (I'm not allowed).
