Wyeast 1968 London ESB – A very good cask conditioned ale strain, this extremely flocculent yeast produces distinctly malty beers. Attenuation levels are typically less than most other yeast strains which results in a slightly sweeter finish. Ales produced with this strain tend to be fruity, increasingly so with higher fermentation temperatures of 70-74 °F (21-23 °C). A thorough diacetyl rest is recommended after fermentation is complete. Bright beers are easily achieved within days without any filtration.
Flocculation: High Apparent Attenuation: 67 – 71% Apparent ABV Tolerance: 9% Temperature Range: 64-72°F (18-22°C)
