Wyeast London ESB Ale 1968

This extremely flocculent yeast produces distinctly malty beers. Attenuation levels are typically less than most other yeast strains making for a slightly sweeter finish. Ales produced with this strain tend to be fairly fruity. Fruitiness will increase with higher fermentation temperatures (70-74F, 21-23C). Diacetyl production is noticeable and a thorough rest is necessary. Yeast traps trub easily and autolysis during storage is accelaerated. A very good cask conditioned ale strain due to rapid and complete flocculation. Brilliantly bright beers are easily achieved without any filtration.       

Flocculation: Very High
Attenuation: 67-71%
Temperature Range: 64-72F, 18-22C
Alcohol Tolerance: 10% ABV

**Purchasing an Ice Pack and/or 2-day shipping, as well as doing a yeast starter, is always recommended to ensure the viability of liquid yeast.  As a courtesy, one ice pack has already been selected in the product options section and will be added to your cart when you buy the yeast unless you deselect this option.  We will cover shipping costs for this first ice pack, additional ice packs can be purchased here**

Please note: We recommend liquid yeast be shipped using 2-day air with adequate ice packs (1-2 ice packs per vial, available here), especially during warmer months. To reduce shipping costs, customers should order yeast separately from other products a few days before planning to brew. This provides a chance to make a yeast starter to ensure a strong and healthy ferment. Having a backup yeast, whether liquid or dry, is always a good idea. A yeast starter will also confirm the viability of the yeast. If the yeast was damaged during shipping, we can replace a yeast that doesnﾒt start, but not a beer that does not ferment.
