Alpine Lager
Swiss lager, rapid fermentation
Description
Alpine Lager is a classic Swiss yeast for producing a wide range of lager and pilsner beers with rapid fermentation. The yeast profile makes it possible to brew excellent pale ale. Yeast with excellent fermentation performance and ability to produce clean and bright lagers with minimal diacetyl, fresh taste and floral notes.

Method of use
Dosage: From 80 to 150 g/hl, increasing the dosage of yeast in difficult and high gravity fermentation conditions.
Rehydration: Rehydrate the yeast in 10 times its weight in clean boiled water at 25-30°C in a sterile container. Make sure all the yeast is in contact with the water, leave it for 15 minutes and then stir gently for complete rehydration. Leave it for another 5 minutes at 25-30°C. The rehydration process should not exceed 30 minutes to avoid damaging the viability of the yeast. Inoculate the rehydration yeast into the fermentation vessel. The temperature difference between the wort to be inoculated and the rehydration yeast should never exceed 10°C.
