Pub yeast is a very highly flocculant British style ale yeast! Because of its high rate of flocculation, it can produce brilliantly clear beers without the need for filtration. It is a favorite of many brewers in the production of British style bitters, but works well in a range of different British style beers, including milds, porters, stouts, and English IPAs. It produces more esters than the more neutral American yeast strains, and should be given a good diacetyl rest. Because it is highly flocculant, it will settle out of solution very quickly. It can be used to churn out clear beers in a very short amount of time!
