Sending our first barrel-aged sour beer into the world is a special occasion, so we are pairing it with something awesome. Autumn Arch will release four American Wild Ales at an exclusive event on January 29. Calculated Deviation is a tribute to the unplanned nature of all sour beers. As much as we purposely brew for specific flavors, wild yeast adds a beautiful element of adventure and randomness. It's a Calculated Deviation from the dialed-in, methodical, and predictable brewing process of ales and lagers. Join us on January 29 and be the first to embrace the deviation.
