Aroma and flavor for beer

Usage

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.

Packaging

Vacuum aluminum foil packing, 500g/bags, 20bags/carton, 10kg/bag, 1bag/carton.

Storage

Store in low temperature (≤10℃) and dry place, with the shelf life of 24months.
