    1. Origin

    Nottingham British Ale yeast is a single strain selected from a multiple commercial culture used in the United Kingdom. The propagation and drying processes have been specifically designed to deliver high quality beer yeast that can be used simply and reliably to help produce ales of the finest quality. No colours, preservatives or other unnatural substances have been used in its preparation. The yeast is produced in ISO 9002 certified plants.

    Good tolerance to low fermentation temperatures, 14°C (57°F), allow this strain to brew lager-style beer. Recommended 14° to 21°C (57° to 70°F) fermentation temperature range.

    2. Brewing Properties 
    • Quick start to fermentation, which can be completed in 4 days above 17°C. 
    • High attenuation, reaching a final gravity near 1008 (2°P). 
    • Fermentation rate, fermentation time and degree of attenuation is dependent on inoculation density, yeast handling, fermentation temperature and the nutritional quality of the wort. 
    • Shows flocculation at completion of fermentation, and settling is promoted by cooling and use of fining agents and isinglass. 
    • The aroma is slightly estery, almost neutral and does not display malodours when properly handled. Because of flocculation, it may tend to slightly reduce hop bitter levels. 
    • Best when used at traditional ale temperatures after rehydration in the recommended manner. 
    • Lager-style beer has been brewed with Nottingham, however low fermentation temperature requires adaptation of the pitching rate to ensure proper attenuation.

    3. Usage 
    • When the recommended 1gm per litre of active dried yeast is used to inoculate, a yeast density of 5–10 million cells per millilitre is achieved. Brewer may experiment with the pitching rate to achieve a desired beer style or to suit processing conditions. 
    • Sprinkle the yeast on the surface of 10 times its weight of clean, sterilized (boiled) water at 30–35°C. 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. 
    • Temperature shock, at greater than 10°C, will cause formation of petite mutants leading to long-term or incomplete fermentation and possible formation of undesirable flavours. 
    • Nottingham British Ale yeast has been conditioned to survive rehydration. The yeast contains an adequate reservoir of carbohydrates and unsaturated fatty acids to achieve active growth. It is unnecessary to aerate wort.
