Abstract

The invention discloses a low-alcohol wine and a preparation method thereof. The low-alcohol wine comprises the following raw materials in parts by weight: 1000 to 1500 parts of downy grapes, 200 to 300 parts of saccharose, 1 to 2 parts of pectinase, 80 to 150 parts of saccharomycetes, and 800 to 1000 parts of cold boiled water. The method comprises the following steps: picking fresh and mature downy grapes, performing change-temperature treatment on the downy grapes, performing crushing to prepare downy grape juice, performing mixed retting on the downy grape juice and the cold boiled water, inoculating the saccharomycetes, performing clarification, filter sterilization and tinning, so as to obtain the finished product. The low-alcohol wine reduces the final alcohol content of downy grape fruit wine, ensures that the taste of the wine is more round and strong, and keeps the original health care efficacy of downy grape fruit wine products.

Description

Technical field [0001] The invention belongs to the technical field of food processing and biological fermentation, and specifically relates to a low-alcohol wine and a preparation method thereof. Background technique [0002] Wine is made by fermenting grapes. It is rich in polyphenols, resveratrol and other substances that are beneficial to human health. Daily drinking can reduce cholesterol in the body and prevent cardiovascular and cerebrovascular diseases. This makes wine have other Drinks have incomparable health functions and become ideal daily drinks. Studies have shown that drinking 50-100mL of wine a day can exert certain health effects, but overall, the health effects of wine appear to be relatively simple. [0003] Wool grapes contain 18 kinds of amino acids, multiple vitamins and more than 20 essential trace elements such as strontium and iodine, and SOD anti-aging elements with a content of up to 910 units per gram, and are the best raw materials for wine making.
