Wyeast - Lager
Fresh is best, pre-order yours now to obtain the freshest possible yeasts.
Activator Packs contain at inception a minimum of 100 billion cells in a yeast slurry.
The Activator is designed to directly inoculate 5 gallons of standard strength ale wort (1.034-1.060 SG) with good pitching rates.
For lagers, we recommend inoculating the wort at warm temperatures (20-21Â°C), waiting for signs of fermentation, and then adjusting to the desired temperature.
Alternatively, for pitching into cold conditions (1-14Â°C) or higher gravity wort, we recommend increasing this pitching rate.
This can be achieved by pitching additional Activator packages or by making a starter culture.
Due to the occasional unpredictable nature of these yeasts, the maintenance of the wort in totally pre-sanitised conditions & retention of a residual dehydrated yeast as a fail-safe is recommended.
