• Quick start to fermentation, which can be completed in 3 days above 17°C.
• Moderate attenuation, which will leave a relatively high gravity.
• Fermentation rate, fermentation time and degree of attenuation is dependent on inoculation density, yeast handling, fermentation temperature and the nutritional quality of the wort.
• Non-flocculent strain, but some settling can be promoted by cooling and use of fining agents and isinglass.
• The aroma is estery to both palate and nose, and is usually described as a full-bodied, fruity British ale. Does not display malodours when properly handled. Windsor yeast has found great acceptance in producing strong-tasting bitter beer, stout, weizen and hefe weizen.
• Best used at traditional ale temperatures after rehydration in the recommended manner.

• Classified as Saccharomyces cerevisiae.
• A top fermenting yeast.
• The typical analysis of the active dried strain:
Percent solids 93%–95%
Living yeast cells 7 x 109 per gram of dry yeast
Wild yeast < 1 per 106 yeast cells (Lysine method)*
Bacteria < 1 per 106 yeast cells*
