Our Saint Dekkera® Reserve Sour Ale series are naturally soured by spontaneous/wild secondary fermentation and aging in oak barrels with microflora wonderfully unique to our downstate Illinois terroir, where we embrace the individual, wild character of each barrel to produce beers with a wide array of acidity, sourness and unadulterated funkiness. When stored properly (55 degrees F), this beer can be cellared, but please enjoy before you perish.
