Brewing properties

High flocculation.

Apparent attenuation of 75~85% and alcohol tolerance of 10%( v/v).

Quick start to fermentation , which can be finished in 3~4days at 18℃.

Displays slight ester and fruity aroma like tropical fruit and without any unpleased smell if properly handled.

Help to present a bright and nice body.

Aroma and flavor for beer


Rehydrate the yeast in 5~10 times its weight of boiled water or diluted wort(2:1 water to wort) at 22~30℃ in a disinfectant container.

Gently stir for 5 minutes to suspend yeast completely and leave it for 10~20 minutes.

Then adjust temperature to that of the wort if there is a temperature shock greater than 10℃ by mixing some wort.

Just inoculate without delay and blend the yeast and wort by the circulating pump.

The whole process should be limited to 30 minutes to reduce risk of other microbial invasion.

It is not necessary to aerate wort to help the yeast achieve active growth.
