After brewer's wort completes, ferment.Brewer's wort is added saccharomycete, is transported to fermentation after supercooling
In tank, start to ferment.Traditional handicraft is divided into primary fermentation and post-fermentation, carries out in different fermentors respectively, currently popular
The practice is that primary fermentation and post-fermentation are carried out in a tank.
Maltose in brewer's wort is mainly transformed into alcohol using saccharomycete by primary fermentation, preferably, before described
Fermentation is divided into low bubble phase, high bubble phase and falls the bubble phase；High bubble phase control fermentation temperature is no more than 12 DEG C, and described to fall the bubble phase be two
It, controls temperature daily and declines 0.4~0.9 DEG C, consumption sugar 0.5~0.8%.Each period of primary fermentation is described below.
The low bubble phase: yeast becomes owner of fermentation vat, 4~5 hours post-fermentation liquid through growth after a period of time is laggard in propagation tank
There is pure white and fine and close foam in surface, and spreads from pool side to centre, gradually forms cauliflower-shaped, this process will maintain one
By two days, extract will decline 0.6%~1.0% daily, rise 1 DEG C or so daily if not cooling temperature, pH value
4.7~4.9 can be dropped to.
The high bubble phase: froth bed swells after the low bubble phase, can achieve 30 centimetres, gently blows froth bed open, it can be seen that
Great amount of carbon dioxide bubble up emits, since hop resin and protein tannin complexes are constantly precipitated in wheat juice, froth bed by
Fade to brown color.The high bubble phase will generally continue two to three days, daily hypoglycemic 1.2~2.0%.If being lower than this numerical value, say
Bright fermentation is not vigorous, general third day or reaches highest fermentation temperature on the 4th day.It is vigorous due to fermenting, need manually cooling protect
Hold certain temperature.Cold fermentation control, fermentation temperature are no more than 9 DEG C, and hot fermentation is no more than 12 DEG C, and acidity reaches maximum, pH
Value drops to 4.4~4.6.
Fall the bubble phase: after the high bubble phase, Yeast proliferation just be stopped, and hypoglycemic speed is also slack-off, and foam is faded simultaneously
And color burn is to sepia.Falling the bubble phase is usually two days, daily 0.4~0.9 DEG C of control products temperature decline, and consumption sugar 0.5~
0.8%, pH value is kept constant or rise slightly.As carbon dioxide bubble is reduced, foam retraction and yeast cells cohesion
Precipitating, karusen surface gradually form foam, hop resin, protein polyphenol complex, these material compositions bubble lid, this layer bubble
Lid is tenne membranoid substance, and thickness is up to 2~4 centimetres.
Preferably, brewer's yeast is inoculated with before carrying out primary fermentation, inoculation method are as follows: by beer yeast slurry and fit
Amount cold wheat juice (preferably quintuple) uniformly mix, 10~15 DEG C heat insulating culture 10~12 hours, wait yeast start budding breeding
Later, it is pressed into yeast propagating tank using aseptic compressed air, and brewer's wort to be fermented uniformly mixes.
Post-fermentation mainly generates some flavor substances, excludes the peculiar smell in beer, and promote the old ripe of beer, this
Period controls certain pressure inside the tank, is retained in the carbon dioxide generated when rear ferment in beer.Preferably, post-fermentation when
Between be 7~10 days, initial temperature is 3~4 DEG C, and averagely hypoglycemic enters lower than gradually cooling to 1~2 DEG C after 0.3%, 7 days daily
Low temperature stores the wine phase, this phase temperature is relatively low, and yeast fermentation stops.
After fermentation, it is filtered sterilizing, by jasmine tea beer by filtering, removes the ferment in jasmine tea beer
