AlphaExtract 20%

Overview

AlphaExtract 20% is a pure, aqueous solution of natural alpha acids in the form of potassium salts, derived from CO2 hop extract.

Alpha acids are unique to hops and naturally inhibit the growth of gram positive bacteria, such as Lactobacillus. Approximately 20 ppm of AlphaExtract 20% can inhibit the growth of most gram positive bacteria under ideal conditions.

AlphaExtract 20% is food grade, kosher and not an antibiotic.
