Frequently asked questions about SafLager W-34/70 500 g
How much yeast do I need?
Fermentis recommends 80–120 g per hectolitre. A 500 g pack is therefore enough for about 4–6 hl of wort, depending on the dosage.
What temperature should W-34/70 ferment at?
The ideal fermentation temperature is 12–18 °C. Lagers benefit from a diacetyl rest towards the end of fermentation and then time cold.
Does the yeast need to be rehydrated?
No. Fermentis states that W-34/70 can be sprinkled directly onto the wort at fermentation temperature, or rehydrated first in sterile water or boiled, hopped wort at 15–25 °C.
How long does the yeast keep?
Shelf life is 36 months from the production date. Store the yeast below 24 °C for up to 6 months and below 15 °C for longer storage.
