It is a pretty good tour. A definite larger brewery. I would suggest touring somewhere like Surly if you have a chance. You get to meet people who actually do the work at Surly rather than volunteers at Summit.
I lived in the cities from 90-93 and fell in love with Summit Pale ale. Would go to Liquor Lyle's and get a pitcher of it to go with the free wings during Happy Hour. I just had that old bartender's name on the tip of my tongue.....
I moved to Bend and started working at Deschutes Brewery and discovered Mirror Pond. When I would go back to Mlps for holidays, I would bring a case of Mirror Pond for my step dad and he always had a case or 2 of Summit for me in exchange.
Now they live in Tucson and it doesn't look like I will be having a Summit Pale ale anytime soon. Enjoy one for me please!
