Belle Saison is a Belgian-style ale yeast selected specifically for its ability to create Saison-style beers. Belle Saison lets brewers create Saison-styles easily and with all the expected characteristics noted for this classic style. Classified as a Saccharomyces cerevisiae var. diastaticus and designed for warm-temperature fermentation true to traditional production methods, beers brewed with Belle Saison exhibit the “Farmhouse” flavors and aromas making for fruity, spicy and refreshing beer.
Classified as a Saccharomyces cerevisiae var. diastaticus, a top fermenting yeast. Typical Analysis of Belle Saison yeast: Percent solids 93% – 97% Living Yeast Cells ≥ 5 x 109 per gram of dry yeast Wild Yeast < 1 per 106 yeast cells Bacteria < 1 per 106 yeast cells Finished product is released to the market only after passing a rigorous series of tests *According to the ASBC and EBC methods of analysis
In Lallemand’s Standard Conditions Wort at 20°C (68°F) Belle Saison yeast exhibits:
Vigorous fermentation that can be completed in 4 days
High Attenuation and Low Flocculation
Aroma and flavor is traditional of Saisons with citrus and pepper notes.
The optimal temperature range for Belle Saison yeast when producing traditional styles is 15°C(59°F) to 35°C(95°F)
Saccharomyces cerevisiae var. diastaticus strains are capable of utilizing some types of dextrins. Extra care should be taken to ensure proper cleaning procedures are in place to avoid any cross-contamination with other brews. Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
Flavour and Aroma:
Depending on the desired gravity of the beer, among other variables, different yeast pitching rates should be applied. For Belle Saison yeast, pitching rate varies between 50 grams and 100 grams of active yeast to inoculate 100 litres of wort. A pitching rate of 50g per 100L of wort to achieve a minimum of 2.5 million viable cells per ml. A pitching rate of 100g per 100L of wort to achieve a minimum of 5 million viable cells per ml. The pitching rate may be adjusted to achieve a desired beer style or to suit processing conditions. Belle Saison has an ABV tolerance of 15%. For beers above 15%, the yeast will require nutrient addition such as 1g/hL of Servomyces.

Rehydration of Belle Saison is recommended for use, and will reduce osmotic stress on the yeast when rehydrated and pitched in liquid form. Rehydration guidelines are quite simple, and present a much lower risk of contamination than a starter, which is unnecessary with dried active yeast. Sprinkle the yeast on the surface of 10 times its weight in clean, sterilized water at 30-35°C (86-95F). Do not use wort, or distilled or reverse osmosis water, as loss in viability will result. DO NOT STIR. Leave undisturbed for 15 minutes, then stir to suspend yeast completely, and leave it for 5 more minutes at 30-35°C. Then adjust temperature to that of the wort and inoculate without delay. Attemperate in steps at 5-minute intervals of 10°C to the temperature of the wort by mixing aliquots of wort. Do not allow attemperation to be carried out by natural heat loss. This will take too long and could result in loss of viability or vitality.
