A lot of this was shot in Boise. Swill just landed on shelves again last week. IMO, it is a "sophisticated" radler.... Berliner base with grapefruit soda.
People have been getting excited about swill for years. My brother's frat house at UVA in the mid-60s had a free beer machine paid for with dues. Some guys made out like bandits, some flunked out!
