Two Greenville, S.C.-based breweries have collaborated on not one, not two, but four different beers in a new series.

Thomas Creek-Birds Fly South American Sour Series Raspberry

The beers from Thomas Creek Brewery and Birds Fly South Ale Project all use the same “golden saison” base, but each of the four variants are conditioned on different fruit for up to one year. The beers are being brewed and bottled at Thomas Creek Brewery.
