Eiswein and preparation technology thereof

Abstract

The invention provides eiswein. The eiswein includes, in mass percent, from 64.5 to 65.4% of water and from 34.5 to 35.4% of concentrated juice, wherein the water accounts for 65%, and the concentration juice accounts for 35%. The preparation technology of the eiswein includes following steps: (1) filtering and performing reverse osmosis treatment for raw water into drinking water to be reserved; (2) squeezing fruit, filtering fruit pulp and concentrating into juice to be stored at low temperature to be reserved; (3) using the water obtained in the step (1) into the concentrated juice obtained in the step (2) to dilute the concentrated juice into juice with the sugar degree of 350-400g / L, and feeding the juice into a fermentation tank to ferment into raw wine in a sugar maintaining manner; (4) keeping the sugar degree of the raw wine higher than 120g / L when the alcoholic strength of the raw wine in the fermenting tank reaches 9-11%vol, filtering the raw wine and feeding the filtered raw wine in an ageing tank to age into the eiswin at low temperature ranging from 8 DEG C to 10 DEG C. A low-temperature sugar maintaining fermenting process for juice is adopted to the eiswein, fruit deep processing technology is provided, and the problems that income of orchard workers is not increased when fruit harvest is good, and eiswein does not appear in markets are resolved. Besides, the sugar and the flavor of the fruit are kept to the greatest extent, the taste of the eiswein is improved, and the eiswein has great look and taste.

Description

technical field [0001] The invention belongs to the technical field of wine processing, and in particular relates to ice fruit wine and a preparation process thereof. Background technique [0002] Fruit is a seasonal crop, and the area and scale of modern planting are large. Once the fruit is ripe, there will be a large number of fruits on the market in a short period of time, resulting in a saturated market and a backlog of stocks, especially late-ripening fruits. Fruits are not easy to preserve for a long time. Fruit farmers need to continue to invest in fruit storage, resulting in high yields but not good harvests. In addition, there is no such product as iced fruit wine on the market. Therefore, deep processing of fruits is an urgent need for fruit farmers and the market. Contents of the invention [0003] The invention provides an ice fruit wine and a preparation process thereof, which solves the problems in the background art that fruit farmers have a high yield but ...
