I probably shouldn't have favorites, but I just can't help myself. If you can only visit one brewery in the Bitterroot Valley, this should be the one.
Bitter Root Brewery is the real deal - fantastic beer and amazing food. No really. The food is so good, they are in my Top 3 Places to Eat. They have an actual chef on hand who develops seasonal menus with a broad variety of items. I have yet to have anything that wasn't tasty.
Why We Love Bitter Root Brewery
The food. It's such a joy to have excellent food to compliment the tasty brews.
