Big Sky always has 2-4 gluten free options on tap. I went last week and they had three seltzers (which rotate... there was mango, lemon ginger basil, and huckleberry lemonade at the time) and a huckleberry tea drink listed as GF. I had the tea and really enjoyed it. One of the owners' wives has Celiac, which is why they were the first brewery in Missoula to make seltzers. I feel very confident going to Big Sky.
