Problems solved by technology

However, because the production of ice wine requires the grapes to be frozen in the natural environment without being picked, it is best to pick the frozen grapes between -7°C and -10°C. On the one hand, the output is extremely limited, resulting in very high prices. Only a few people can afford it; on the other hand, ice grapes that grow naturally have geographical and environmental restrictions. In order to obtain grapes with high sugar content, vines are mostly planted in areas with sufficient sunlight and less rain, especially desert areas. Therefore, the grapes hang on the vine for too long after they are mature, and they tend to become raisins, which cannot be used as raw materials for wine; in addition, the vines are frozen, and the damage is very serious, and the growth of the next year will be greatly affected.

Abstract

The invention discloses a process for producing grape wine by artificially freezing grapes. The process includes the following procedures: a freezing procedure-an ear selecting and stem removing and crushing procedure-a squeezing procedure-a wine juice clarification procedure-a fermentation procedure-an aging procedure. The process imitates the production process of ice grape wine, is simple, is not limited by region and environment, has no damage to grapevines, and is suitable for large-scale production. Through delaying the harvesting time of grapes, a grape raw material with high sugar content and strong fruit aroma can be obtained; through the process of artificially freezing grapes, moisture in the grapes is frozen and removed by squeezing, so that the aim of sugar concentration is achieved, and the sugar degree of the grape wine is improved; and moreover, after the grape is frozen, the cells of the grape skin are destroyed, and the beneficial substances inside the grape skin arefully and effectively separated and enter into the grape juice, so that the taste, appearance and aroma of the grape wine are finally improved, and the quality of the grape wine is improved.

Description

Technical field: [0001] The invention relates to a wine production process, in particular to a process for artificially freezing grapes to produce wine. Background technique: [0002] Ice wine is a kind of wine wine with excellent taste, pleasant aroma and rich nutrition. Ice wine has the functions of nourishing, anti-aging, beautifying, reducing fat, preventing and treating cardiovascular and cerebrovascular diseases, quenching thirst and diuresis, etc. It is a very beneficial wine for the body products. Ice wine is brewed from grapes that freeze naturally on the rack. However, because the production of ice wine requires the grapes to be frozen in the natural environment without being picked, it is best to pick the frozen grapes between -7°C and -10°C. On the one hand, the output is extremely limited, resulting in very high prices. Only a few people can afford it; on the other hand, ice grapes that grow naturally have geographical and environmental restrictions. In order ...
