Provided is a method for recovering linalool from hops at a high rate in the process of extraction with supercritical carbon dioxide. Also provided is a hop extract containing linalool in a high proportion.

In a method for obtaining a hop extract using supercritical carbon dioxide, the pressure of carbon dioxide in an extraction tank is adjusted to be in the range of 8 to 10 MPa, and the temperature of a separation tank is adjusted to not higher than 30 C. According to this method, an extract having a high ratio of the amount of linalool to that of -acids can be obtained. The recovery rate of linalool from hops is not lower than 33 mass %. The extract can be used as an additive for production of foods and beverages.

An automated or semi-automated beer brewing system may adjust a brewing session based on data collected during the brewing session. The adjustments may attempt to achieve a set of desired taste characteristics, even though a brewing session may then deviate from an intended recipe. A performance model of the brewing system may include taste characteristic effects and operational aspects of an automated brewing system, and may be used to calculate changes to various brewing steps. A control system may analyze various measured parameters to determine deviation from an intended recipe, and may use the performance model to calculate updated brewing steps that may attempt to achieve the desired result. When such measured parameters indicate a malfunction, a brewing session may be paused or terminated.

A beer maker may include a fermentation vessel accommodated in a space and having a beer brewing space, a main channel communicating with the beer brewing space, a sub-channel communicating with the beer brewing space, a gas pump connected to the sub-channel to pump gas to the sub-channel, and a gas valve at the sub-channel. Ingredients for brewing beer are supplied to the beer brewing space through the main channel, and gas is supplied to the beer brewing space through the sub-channel, so that beer can be simply brewed while minimizing a user from opening the lid.

A beer maker may include: a fermentation container having a beer brewing space, a thermoelectric module (or device) for heating or cooling inside of the housing, an ingredient supplying device, and a main channel connecting the ingredient supplying device and the beer brewing space to each other. Ingredients may be fermented in the fermentation vessel container, which is protected by a housing. Ingredients may be provided into the beer brewing space in a state that a lid is closed, a foreign substance may be minimized from being contained in the beer.

The invention relates to a method for preparing a brewed beverage, in particular for brewing a beer, comprising adding alkali metal salts of alpha-acids and beta-acids to wort before or during boiling of the wort, andafter boiling of the wortsubjecting the wort to a fermentation step wherein the brewed beverage (or beer) is produced. The method comprises contacting (blending or mixing) an alpha-acid and beta-acid containing matter with one or more alkali metal compounds, thereby forming alkali metal humulates and alkali metal lupulates, prior to the addition to the (boiling) wort.

This disclosure relates to a method and device for the operation of a combine harvester with multiple work elements for harvesting a crop via a driver assistance system. In one example implementation, a method for operating such a combine harvester includes determining separately a harvest setting for the crop and a machine configuration of the combine harvester, preselecting a process control strategy among a plurality of process control strategies based on the harvest setting and machine configuration wherein each of the plurality of process control strategies is aimed at fulfillment of at least one harvesting quality criterion stored in the memory of the combine harvester, and automatically determining at least one machine parameter for the work elements of the combine harvester according to the preselected process control strategy and controlling the work elements corresponding to the at least one machine parameter.

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 beer making system may use a detachable vessel to contain liquid during the mashing and boiling steps, and may also be used during the fermentation steps of beer making. The beer making system may recirculate liquid through the vessel, then select between several flow paths during the beer making process. A removable reservoir system having a grain reservoir and several hops or adjunct reservoirs may be selected as a flow path, as well as a bypass flow path. A programmable controller may cause liquid to recirculate through a heater and one of the various flow paths, the sequence, timing, and temperature profile of which are defined in a recipe for a particular beer.

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.

A pulp container may contain beer making ingredients during the beer making process. The container may have a bag, filter, or other sieve that may retain the ingredients during the brewing process, and may be compostable and disposable after the brewing process has completed. The container may contain prepared ingredients that may be pre-packaged such that a user may drop the container with the prepared ingredients into a system for brewing beer. In some cases, a container may contain grains and other ingredients that may be used for a mashing step. In other cases, a container may contain one or more hops charges and may have boiling or near boiling water. The brewing system may include recirculating brewing systems, as well as other types of brewing techniques.
