The invention relates to the technical field of beer
brewing, and particularly discloses a preparation method of long-acting fresh stable-taste original beer, which comprises the following steps:
raw material pretreatment, saccharification and
filtration, boiling and hops addition, cooling and
oxygenation,
fermentation, dry addition of hops and after-
ripening. Wherein the raw materials comprise Pearson malt, wheat malt, burnt
crystal malt and malt with an
antioxidant function in a weight ratio of (70-85): (5-15): (5-10): (0.5-5); the
fermentation method comprises the following steps: inoculating
saccharomycetes into wort for
fermentation, and then heating for
diacetyl reduction; the step of dry addition of hops comprises the following steps: adding fragrant flower type hops into a
fermentation system, and extracting for 3-5 days; and after the extraction is finished, adding modified
konjac glucomannan, uniformly stirring and standing. According to the preparation method of the original pulp beer, the problems that traditional original pulp beer is prone to oxidation, unstable in
flavor, large in colloidal precipitate amount, rapid in taste deterioration and the like can be solved, and long-term stability of the fresh taste of the original pulp beer is achieved.
