1968 London ESB Ale Yeast
Probable origin: London,
England
Beer Styles: British Pale Ales, Special Bitters
Commercial examples may include: Fullers London Pride, Young's and
Greene Kings
Unique properties: This
extremely flocculant yeast produces distinctly malty beers. Attenuation levels
are typically less than most other yeast strains making a slightly sweeter
finish. Ales produced with this strain tend to be fairly fruity. Fruitiness
increased with higher fermentation temperatures 70-74º F, (21-23º C). Diacetyl
production is noticeable and a thorough rest; 50-70º F, (10-21º C) is
necessary. Yeast traps trub easily and autolysis is possible. A very good cask
conditioned ale strain due to thorough flocculation characteristics. Beers
become readily bright within days. Brilliant beers easily achieved without any
filtration. Alcohol tolerance approximately 9% ABV. Flocculation - high;
apparent attenuation 67-71%. (64-72° F, 18-22° C)
