Yellow to amber solution containing the potassium salts of alpha acids from hops.
Alpha Extract is a pure, aqueous solution of natural alpha acids in the form of potassium salts, derived from CO2 extract.
Alpha Extract imparts a smooth bitterness to beer with a bitterness only 10% of that of iso-alpha acids.
In addition, Alpha Extract improves the stability and cling of beer foam.
Alpha Extract provides a smooth (sensory) bitterness at a dosing rate of 7 – 8 mg/l, depending on the type of beer. However, this will lead to an increase in the analytical bitterness value. The percieved bitterness of Alpha Extract is smoother than that of pure iso-alpha acids. At the same time, Alpha Extract enhances the stability and the cling of beer foam. An improvement in beer foam is already evident at 3 – 4mg/l of alpha acids in the finished beer.
