Join us Saturday for a fun all-day event we’re doing. Mystery Sour Saturday is a unique, new thing, that will keep you and your tastebuds guessing. We will have 4 sours on tap that are new for Saturday (2 are brand new, never made before releases). Then, you have to guess the ingredients we used. People who guess a certain number of correct ingredients are entered into a raffle for some cool prizes. See you soon. #craftbeer #knoxbeer #knoxvilletennessee
