Methods and systems for making refined fermented beverages, including neutral malt beverages, having reduced or negligible levels of organic acids, particularly acetic acid, relative to bright beer and other untreated fermented beverages. The refined fermented beverages are produced using a caustic dosing system to neutralize naturally-present organic acids typically present in untreated fermented beverages and convert them into their respective conjugate bases as salts. The salts of the neutralized organic acids are then removed or separated from the treated fermented beverage to form the refined fermented beverage.
Methods and systems in a process for disinfecting or sterilizing a fermented beverage and/or a composition utilized in a fermentation process to produce a fermented beverage, using ultraviolet light. Such methods and systems can be coupled with processes for neutralizing unwanted acidic congeners and separating the resulting salts of the acidic congeners to produce a refined fermented beverage, including but not limited to a neutral malt base, gluten-free base, gluten-reduced base, grain-neutral spirit, wine base, and a sugar-brew base. Drinkable fermented beverages, including but not limited to flavored malt beverages and hard seltzer beverages, can also be disinfected or sterilized with ultraviolet light using any of the systems or methods described herein.
