London ESB is a true English ale strain selected for reliable fermentation performance and moderate ester production that lets the flavors and aromas of malt and hops shine through. London ESB was selected from the Lallemand yeast culture library, and is an excellent choice not only for brewing Extra Special Bitter but for other authentic heritage UK styles like Pale Ale, Bitter and Mild. London ESB may also be used in the production of Ciders.
In Lallemand’s Standard Conditions Wort at 20°C (68°F) London ESB yeast exhibits:
Vigorous fermentation that can be completed in 3 days
Medium attenuation and Low flocculation
Neutral to slightly fruity and estery flavor and aroma, allowing Malt aromas and flavors to shine through
The optimal temperature range for London ESB yeast when producing traditional styles is 18°C(65°F) to 22°C(72°F)
London ESB 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 gravities and 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 of the wort.
