Dosage / Temperature
50 to 80 g/hl at ideally 18-26°C (64.4-78.8°F).

Lesaffre know-how and continuous yeast production process improvement generates an exceptional quality of dry yeasts able to resist to a very wide range of uses, incl. cold or no rehydration conditions, without affecting their viability, kinetic and/or analytical profile. Brewers can choose usage conditions that fit the best their needs, i.e.:

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 25 to 29°C (77°F to 84°F). Leave to rest 15 to 30 minutes, gently stir and pitch the resultant cream into the fermentation vessel.

Recommended Fermenter

Research has shown that in order to extract the most flavour from hops and yeast, and to minimise contact with oxygen, pressure fermenters are the best fermenters for any style of beer which is why the manufacturer recommends to use one of the below fermenters:

Dry Yeast Frequently Asked Questions

Below you will find the questions we get asked the most regarding our dry yeasts.
Please click on one of the questions below to see the answer.

Dry Yeast Usage

Is it recommended to rehydrate dry yeast?

A big part of homebrewing comes down to what works best for you and also following producers' recommendations. We would encourage you to read instructions before use.

Do I need to rehydrate the yeast before pitching?

Typically, dry yeasts do not need to be rehydrated before use and can be pitched directly into our fermenters. However, some brewers prefer to rehydrate dry yeasts as they think it speeds up the start of fermentation.

How do I rehydrate dry yeast?

To rehydrate yeast, simply add around 300ml of lukewarm water to a sanitised conatainer, and add the content of the packet then cover with a layer of tin foil. You will notice that after an hour or so, the yeast will start to buble and activate.

Storage Recommendation

How do I store my dry yeast?

Store in the fridge or dry and cool place.

How long can I store my dry yeast for?

Dry yeast can be stored for extended periods of time. Please refer to the package for the best before date.
