ok,men jeg lager undergjæret øl. Gjærer på 11 grader. Gjæringen går jo langsommere på disse. Men Saflager skriver jo også i sin info at den bør tilsettes på 22 grader om den tilsettes tørr.Veit ikke om det er så farlig. Jeg strødde B-134 rett i dunken på 16 grader, og den kom i gang helt fint - og har jobba helt fint, også.
Fermentis sier du kan strø den rett i vørteren på gjæringstemperaturen:
① Direct pitching:
Pitch the yeast directly in the fermentation vessel on the surface of the wort at or above the fermentation temperature. Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available to avoid clumps. Ideally, the yeast will be added during the first part of the filling of the vessel; in which case hydration can be done at wort temperature higher than fermentation temperature, the fermenter being then filled with wort at lower temperature to bring the entire wort temperature at fermentation temperature.
② With prior rehydration:
Alternatively, sprinkle the yeast in minimum 10 times its weight of sterile water or boiled and hopped wort at 15 to 25°C (59°F to 77°F). Leave to rest 15 to 30 minutes, gently stir and pitch the resultant cream into the fermentation vessel.
