Brewing Properties
In Lallemand’s Standard Conditions Wort at 20°C (68°F) LalBrew® Windsor yeast exhibits:
Vigorous fermentation that can be completed in 3 days
Medium attenuation and Low flocculation
Fruity and Estery flavor and aroma, typical of traditional English style ales
The optimal temperature range for LalBrew® Windsor yeast when producing traditional styles is 15°C(59°F) to
22°C(72°F)
Windsor does not utilize the sugar maltotriose (a molecule composed of 3 glucose units).
Maltotriose is present in wort in an average 10-15% of all malt worts. The result will be fuller body and residual sweetness in beer. Be advised to adjust mash temperatures according to desired result.
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality ofthe wort.
