A fruit wine aroma enhancement brewing technology using cutinase belongs to the technical field of fruit wine brewing. According to the present disclosure, in order to solve the problem that fruit wine prepared through an existing fruit wine fermentation technology is poor in quality such as aroma and taste, Muscat grapes or apples are adopted as raw materials, and after crushing, separating peel residue, performing peel residue heat treatment and enzyme treatment, mixing the treated peel residue and clear juice, adding auxiliary materials (potassium metabisulfite, pectinase and β-glucosidase), adjusting a sugar degree, inoculating a high-glycerol-field yeast and fermenting with temperature controlled, inoculating an active dry yeast and fermenting with the temperature controlled until fermentation is finished, separating and removing the peel residue, fining, filtering to remove residue, performing stabilizing treatment and performing filtration sterilization, dry grape wine or cider is obtained. The present disclosure can be used in large-scale production of dry fruit wine.

The present invention discloses a process for preparing a sparkling alcoholic beverage resulting from the maceration of hops and/or its derivatives in wine with the addition of wine concentrate, vegetable water and/or water, fruit or vegetable concentrate and/or sugar, in order to reduce the alcohol content of wine, and which is gasified by a second alcoholic fermentation and/or addition of carbon dioxide. Through this process a sparkling alcoholic beverage having between 5 and 15% alcohol, a sugar content between 0.1 and 200 g/L, with a total acidity between 4 and 8 g/L is obtained having hops aroma, flavor and bitterness combined with aromas inherent to wine.

Methods and systems to control flexible gas fermentation platforms for improved conversion of CO.sub.2 into products is developed and particularly relates to a control process and system to control a ratio of feedstock gases and maximize the concentration of inert components in a bioreactor tail gas stream and or bioreactor headspace. Improved carbon utilization results though providing the most beneficial ratio of substrates to the bioreactor of the fermentation process.

A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage. A gas cylinder can include a cap with a flange and catch below the flange. The catch can be engaged by a cylinder support to move the cylinder into contact with a piercing element to pierce the gas outlet of the cylinder and form a seal between the cylinder and gas receiver. A pressure indicator can have a single pressure sensor to indicate a capacity of a gas cylinder to deliver pressurized gas and a pressure in a beverage container.
