USAGE
Adjust the pitching rate according to the beer style, original gravity of the wort and temperature of fermentation. For Essential® Lager, a pitching rate between 100 and 200 grams per 100 liters of wort is recommended for most fermentations.
PITCHING
Rehydration and direct pitching of dry yeast into wort are both acceptable methods for inoculating fermentation.
Rehydration of Lallemand Brewing yeast in sterile water prior to pitching into wort has been shown to reduce stress on the cell as it transitions from dry to liquid form. However, for most fermentations, this stress is not significant enough to affect
fermentation performance and flav or, so good results will also be achieved when direct pitching dry yeast into wort. Use of a rehydration nutrient such as Go-Ferm Protect Evolution has been shown to improve fermentation performance for difficult fermentations.
Measure the yeast by weight withinthe recommended pitch rate range.
Pitch rate calculators optimized for liquid yeastmay result in significant
overpitching.
DIRECT PITCH
Dry pitching is the preferred method of inoculating wort. This method is simpler than rehydration and will give more consistent fermentation performance and reduce the risk of contamination. Simply sprinkle the yeast evenly on the surface of the wort in the fermenter as it is being filled. The motion of the wort filling the fermenter will aid in mixing the yeast into the wort.
For Essential® Lager, there are no significant differences in fermentation performance when dry pitching compared to rehydration.
REHYDRATION
Rehydration of yeast prior to pitching should be used only when equipment does not easily facilitate dry pitching. Significant deviations from rehydration protocols can result in longer fermentations, underattenuation and increased risk of contamination. Rehydration procedures can be found on our website.
Measure the yeast by weight within the recommended pitch rate range. Pitch rate calculators optimized for liquid yeast may result in significant overpitching.
STORAGE:
Essential® Lager should be stored dry below 4°C (39°F).
Dry yeast will rapidly lose activity after exposure to air. Do not use 500g packs that have lost vacuum. Opened packs must be re-closed, stored in dry conditions below 4°C, and used within 3 days.
Do not use yeast after expiry date printed on the pack.
