The brewing process of half-juice watermelon beer

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 invention belongs to the technical field of beer brewing, in particular to a brewing process of half-juice watermelon beer, in particular to a fruity beer brewing method using barley malt and freshly squeezed watermelon juice as main raw materials. Background technique [0002] my country's watermelon planting area is large, both in 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, due to the relatively concentrated market period of watermelon, coupled with the fact that watermelon is not resistant to storage and transportation is inconvenient, the price of watermelon is on the low side, making it difficult to increase the income of melon farmers, which greatly discourages the enthusiasm of melon farmers in planting melons, and is harmful to the healthy and stable development of my country's watermelon industry. created an obstacl...
