Lallemand Belle Saison
The reliable dry saison strain. Won't stall like WLP565 — but produces a different (less peppery) beer.
What it tastes like
Belle Saison solves the WLP565 problem: where the classic Dupont strain notoriously stalls at 1.025 and demands 90°F+ temperatures, Belle Saison just ferments. Cleanly, predictably, and to a dry finish (often 90%+ attenuation) at standard ale temps. The trade-off: it produces less of the peppery, earthy phenolic character that defines a classic Belgian saison. You get a dry, bright, slightly fruity farmhouse ale rather than the dense complex Dupont profile.
Best in these styles
Fermentation profile
Ferments cleanly at standard ale temps without needing the 90°F+ heat ramp WLP565 requires. Reaches 90%+ attenuation reliably. Most batches finish in 7-10 days at 70°F. Drier than most ale yeasts, so plan your recipe for the dry finish — leave more crystal malt for body if you don't want a thin beer.

History
Lallemand released Belle Saison in 2014 as a response to homebrewers struggling with WLP565/Wyeast 3724 stalling. The strain is not a direct descendant of Dupont but produces saison-style results reliably. Within a few years it became the dominant dry saison option, and many homebrew saisons today use Belle Saison rather than the classic liquid strains.
