Finally got 2 of these yeast to keep my husband happy with his favorite ESB brew. Love how this yeast works and the flavor it produces for my ESBs!
London ESB Dry Yeast (Danstar)
I like to brew English beers and I like dry yeast, so I ignored the 2-star reviews. I made an ordinary bitter and an English porter, OG 1.036 and 1.044 respectively. Each beer attenuated 78%. The yeast is a little neutral, a little more ester would be needed to take it to 5 star. It really allows the malts to shine.
I'm typically not one to blame ingredients, but rather fault the brewer for subpar beer. This time, however, I'm not so sure. Brewed a 10 gallon batch, fermented half with this yeast and the other with S-23 Saflager as a Festbier. OG was 1.049. This one finished at 1.017 while the lager did 1.012. Temperature set at 68F for the ESB, 58F for the lager. The ESB fermentation was vigorous for 3 days but then stopped. Resulting beer was notably turbid, sweet and lacked bite, while the lager finished clear and produced beer according to style. Trying to salvage the ESB with addition of corn sugar. I tried a follow up batch harvesting and repitching, but same result: OG 1.052 and finished at 1:018. Unless you are a fan of sweet, cloudy beer or plan to over bitter, I'd stay away from this yeast.
Starts fast and is usually done fermenting my 3-gallon batches in 2-3 days, though here's the problem: it stalls at 55-60% attenuation. I've had this problem twice and have read the same from others. If you read the specs, this yeast does not ferment maltotriose, which is 10-15% of the wort. If you're looking for a sweeter beer with low attenuation, e.g. in a historical English ale recipe, use this one. Personally, I'm not a fan. I'd like my average beers to finish under 1.020.
