Embodiment 1

[0029] A kind of brewing process of half juice watermelon beer, it comprises the steps:

[0030] The first step: malt crushing. Select high-quality barley malt with good solubility, and use the humidification crushing method for crushing (spray an appropriate amount of water with a watering can before crushing, the crushing requires that the wheat skin is broken but not broken, and the endosperm part is finer).

[0031] The second step: saccharification. The saccharification is carried out by two times of cooking, specifically: the saccharification feeding temperature is 36°C, heat preservation for 40 minutes, then slowly raise the temperature to 47°C and heat preservation for 30 minutes, take part of the mash and slowly heat up to 100°C and boil for 30 minutes. Then mix it with the rest of the mash to keep the temperature of the mixture at about 62°C, and keep it warm for 40 minutes until the iodine solution detects that the saccharification is complete. Take part of the ma...

[0041] A kind of brewing process of half juice watermelon beer, it comprises the steps:

[0042] The first step: malt crushing. Select high-quality barley malt with good solubility, and use the humidification crushing method for crushing (spray an appropriate amount of water with a watering can before crushing, the crushing requires that the wheat skin is broken but not broken, and the endosperm part is finer).

[0043] The second step: saccharification. The saccharification is carried out by two times of cooking, specifically: the saccharification feeding temperature is 38°C, heat preservation for 40 minutes, then slowly raise the temperature to 50°C, heat preservation for 30 minutes, take part of the mash and slowly heat up to 100°C, boil for 30 minutes, and then mix with the rest Mix the mash to make the temperature of the mixture reach 62°C, until the iodine liquid detects that the saccharification is complete, then take part of the mash and slowly heat it to 100°C to boi...

Abstract

The invention relates to a process for brewing half-juice watermelon beer. The process comprises the following steps: a) inoculating and fermenting, namely, inoculating and culturing bottom fermentation beer yeast at the logarithmic phase into wort, and meanwhile introducing oxygen till the oxygen concentration is 8-10mg / L; b) adding watermelon juice, namely, when the high kransen of fermentation begins after 2-3 days, adding fresh watermelon juice which accounts for 40% of the total volume of a fermented material, and continuously fermenting; and c) performing later fermentation, namely, performing later fermentation when the content of diacetyl is reduced to be less than 0.1mg / L, and filtering the obtained material by using a kieselguhr filtering method after the later fermentation is completed, thereby obtaining the half-juice watermelon beer, wherein the later fermentation comprises two stages, namely, warm storage and cold storage. According to the process, barley malt and fresh watermelon juice are taken as main raw materials, the flavor substances in watermelon are maintained as much as possible in the low-temperature fermentation process, and the variety of draught beer in summer is enriched.

Description

Technical field [0001] The present invention is a beer brewing technology field, which involves a brewing technology of a semi -juice watermelon beer, especially the fruit brewing method with large malt and freshly squeezed watermelon juice as the main raw material. Background technique [0002] my country's watermelon planting area is large, and the output and quality are far ahead in the world.Watermelon has become a pillar industry in many places and an important way for farmers to increase their income.However, because the listing period of watermelons is relatively concentrated, and the inconvenience of watermelon storage and inconvenience, the price of watermelon is low, making it difficult for the income of melon farmers to increase, greatly cracking down on the enthusiasm of melon farmers, and the healthy and stable development of my country's watermelon industry in China Causes obstacles.The deep processing of watermelon will fundamentally change this situation, greatly ...
