Abstract: Method for the production of a polyphenolic composition from barley malt, including the fundamental steps of: grinding of the malt grains and splitting into two portions, 20% and 80%; mixing each of the two portions with water to obtain an A mixture and a B mixture, the A mixture being prepared with the 20% portion to obtain a mixture of the malt in water at a final concentration between 9.5% and 20%, the B mixture being prepared with the 80% portion to obtain a mixture of the malt in water at a final concentration between 33% and 60%; thermal cycle; separation of the liquid component from the solid component; boiling of the liquid component and the addition of hops; rapid cooling of the wort; storage; in which said thermal cycle consists of a first phase and a second phase, in which the first phase applies to the 20% portion (Mixture A) and the second phase during which Mixture B is added to Mixture A.
