* Classified as Saccharomyces cerevisiae. * A top fermenting yeast. * The typical analysis of London ESB active dry yeast: Percent solids 93%-95% Living yeast cells 5 x 109 per gram of dry yeast Wild yeast < 1 per 106 yeast cells Bacteria < 1 per 106 yeast cells* * Finished product is released to the market only after passing a rigorous series of tests. *According to ASBC and EBC methods of analysis.
* London ESB yeast is best used at a fermentation temperature range of 18-22degC (65-72degF). Fermentation is generally completed in 3-5 days dependent on recipe and process conditions. * Attenuation range 65-75% * Fermentation rate, fermentation time and degree of attenuation are dependent upon inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort. * Produces a clean, well balanced ale. Medium attenuation preserves some beer complexity. Best for well-balanced British style ales.
