LalBrew Windsor™ is a true English ale strain that produces a balanced fruity aroma with lower attenuation due to an inability to metabolize maltotriose. LalBrew Windsor™ is one of the original Heritage Strains selected from the Lallemand Yeast Culture Collection when Lallemand Brewing was founded in 1992. Beers created with LalBrew Windsor™ are usually described as full-bodied, fruity English ales. LalBrew Windsor™ is a consistent and robust strain that produces moderate levels of alcohol and the balanced flavour and aroma characteristics of the best traditional English ales. Traditional styles brewed with this yeast include but are not limited to Milds, Bitters, Irish Reds, English Brown ales, Porters and Sweet Stouts.
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 flavour and aroma, typical of traditional English style ales
The optimal temperature range for LalBrew Windsor™ yeast when producing traditional styles is 15 – 25°C (59 – 77°F)
Windsor does not utilize the sugar maltotriose (a molecule composed of 3 glucose units).
Maltotriose is present in wort in an average of 10-15% of all malt worts. The result will be a fuller body and residual sweetness in the beer. Be advised to adjust mash temperatures according to the desired result.
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
