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. The relative polyphenolic composition obtained according to this method is characterized by the fact that it can be in liquid, powder, dry, and lyophilized form, its use and relative beverage or beer according to the present method not obtained with fermentation methods.

Compositions and methods are disclosed for stabilizing the flavor of a fermented beverage, most particularly beer, by the addition of a composition comprising a tannin and a solid carrier prior to, or during early stages of, fermentation of the beverage. The invention is also directed to the fermented beverage prepared by such a method. The composition may include at least one polyphenol therein and may be in the form of a pellet.

A device for extracting aroma substances from vegetable aroma carriers into a brewing liquid includes a solids separating device for separating the vegetable aroma carriers from the brewing liquid in flow, the solids of the aroma carriers being held back in the solids separating device. The device comprises a heater for heating the suspension of brewing liquid and aroma carriers to an isomerization temperature at which the -acids contained in the aroma carriers are converted into iso--acids.

It has unexpectedly been found that Pichia spp. strains have advantageous properties useful in the beer fermentation process. In particular, Pichia spp. yeast strains can be combined with normal beer yeast strains and different hop varieties in a fermentation process to produce synergistic effectsnamely, the increased production of esters in the fermentation product. More specifically, the yeast can be used to produce increased levels of isoamyl acetate, isobutyl acetate, ethyl propionate, ethyl valerate, ethyl butyrate, ethyl decanoate and ethyl octanoate in beer. In addition, the Pichia spp. strain interacts differently with different hop varieties, so the flavor profile of beer can be tuned by using different combinations of Pichia spp. strains and hops. The present invention relates to a method of brewing beer using a Pichia spp. yeast strain and at least one hop variety, a beer obtainable by such a method and use of a Pichia spp. yeast strain according to the present invention.

A device for extracting aroma substances from vegetable aroma carriers into a brewing liquid, in particular into beer, includes a fluidized bed extractor accommodating a suspension bed including the brewing liquid and solid particles contained in aroma carriers. The fluidized bed extractor has at least an inlet and an outlet for the brewing liquid. A feed pump pumps the brewing liquid from the inlet through the fluidized bed extractor to the outlet. A feeding speed of the feed pump is set to a value at which an average vertical feeding speed of the brewing liquid in the fluidized bed extractor is lower than an average vertical sedimentation speed of the solid particles in the fluidized bed extractor.

A beer filter and a method of brewing beer is disclosed, the beer filter including an outer sheath, an outer permeable sheath disposed in the outer sheath, and an inner permeable sheath disposed in the outer permeable sheath. The method includes steps of disposing an outer permeable sheath within an outer sheath, filling an outer permeable sheath with hops, disposing an inner permeable sheath within the outer permeable sheath, and causing beer to flow from a vessel through and out of the inner permeable sheath, through the hops in the outer permeable sheath, out of the outer permeable sheath and into the outer sheath, and from the outer sheath and back into the vessel.

The present invention relates to new products and processes for making and using hop extract products comprising hop oils present in amounts between about 6 mL/100 g to about 40 mL/100 g, or more. The oil enriched hop extracts of the present invention also contain higher proportions of oil relative to other hop components typically found in hop extracts. Production of the oil enriched hop extracts may comprise a partial or a first extraction of hop materials. In one preferred embodiment, such extraction may occur under pressures of 1700 psi to about 3700 psi for less than three hours. The enriched oil extracts of the present invention can be used to produce beers having enhanced aroma and flavor profiles. The present invention also relates to products and processes for making and using second extractions of hop materials comprising alpha acids present in amounts of, for example, about 50% to about 70% (w/w).
