You can email us at commandes@levureslelabo.com or fill out our custom order form and specify the strain you want, the volume and the wort original gravity of the recipe you intend to use it in.

You can also order a specific quantity of cells if you know exactly what you need. Our online store also offers a selection of standardized products that are regularly in stock.

See our Ordering and Shipping page if you would like to know more.

We calculate your yeast needs according to the use you intend to make of it, i.e., according to the wort original gravity of your recipe, the volume of wort, the type of product you intend to make, and whether or not you intend to reuse the yeast.

If you are doing multiple brews, we recommend that you mention this as it influences the number of cells needed depending on the time and number of brews required to fill your fermenter. If you wish whenplacingan order, you can always specify the inoculation rate of your choice.

Due to the highly variable cell specific gravity between strains,selling our yeast by volume would be very impractical.The specific gravity varies greatly depending on the flocculation capacity of each strain, the cell size and the volume of yeast paste harvested from each production. Therefore, we prefer to sell our yeast by the cell count rather than by volume so that you get the most consistent results possible from one production to the next.

We usually ship our products in 0,5 to 99-litre containers depending on the number of cells you need and the cell density of the batch used. Our containers' volume may be subject to change in some specific cases.

We suggest beer styles that can be brewed with each of our products. These styles are available in our catalogue or on the page of each strain on our online store. Please note that these are only suggestions: nothing prevents you from thinking outside the box and letting your imagination run wild!

Do not hesitate to contact us for advice in choosing a strain for a particular product !

We can make custom yeast blends or any other special request for a minimal additional charge. Simply provide us with the relevant information about your recipe (desired strains, proportions, specific gravity, brew volume) or the number of cells of each strain required in your blend and we will provide you with a formal quote.

Unfortunately, we do not presently sell yeast in homebrew pitches. However, our smallest available size, 0.5 hL, may meet the needs of some homebrewers.

We do offer samples for professional brewers wishing to do small-scale trials. If you are interested, please contact us at commandes@levureslelabo.com.

Our guaranteed in-stock collection ensures a vast inventory of products available for shipment in as little as 2 to 3 business days. If we cannot guarantee your desired shipping date, shipping will be free for that order.

Take advantage of our multiple purchase discount of up to 25% when ordering more than one strain at a time.

''La Réserve'' collection is all our liquid yeasts accumulated over the years. This collection is available to our customers, but inventories are not guaranteed. This means that it may take 3 to 4 weeks to produce the ferment requested.

Please note that a minimum of 15 units (15 litres) is required to start production. Please note that the quantity required can be accumulated over several orders from different customers. You will only be invoiced once production has been confirmed.

From time to time, certain yeasts will be available in reduced stock. To consult our products in stock, click here.

There are as many methods of harvesting yeast as there are brewers. Regardless of the method used, the important thing is to harvest the yeast when its energy supply is at its peak. As a general rule, we recommend harvesting towards the end of the fermentation and removing the first few liters of yeast from the bottom of the tank if it is collected by the cone of the fermenter. We also recommend that you perform a cell count and viability measurement to validate that you will be harvesting enough viable cells for reuse in a future brew.

We do not perform microbiological or physicochemical analyses on finished products for clients.

However, we do offer purification, isolation and characterization of microbial flora by traditional microbiology as well as genetic identification of strains. If you would like to know more about these services, please contact us at commandes@levureslelabo.com.

We also offer a support and guidance service for all sectors of brewing production. Contact us at services@levureslelabo.com and our customer service will get back to you as soon as possible.
