S-04 is a favorite dry yeast to use in the production of all types of beers from the British isles. It is highly flocculant, and as such produces beers of unequal clarity. Flavors are slightly fruity, with an earthy English character, as are aromas. This yeast is especially used in making English style pale ales and bitters, and is similar to some yeast strains used in American breweries when producing heavily-hopped beers. However, it has a wide range of applications, and can be used in almost any British beer. Recommended when a true "English" character and very clear beers are desired.

Beer Styles: Blonde Ale, English IPA, Extra Special/Strong Bitter (English Pale Ale), Oatmeal Stout, Southern English Brown, Special/Best/Premium Bitter, Standard/Ordinary Bitter, Sweet Stout.

Great Versatile Dry English Yeast!
Safale S-04 is a great versatile dry strain of English yeast. I have done side by side fermentations with this strain and a number of liquid English strains. While the liquid strains usually do well, I am always surprised how S-04 holds its own against the liquid strains. Usually if I am doing a 10 gallon batch of English beer, I will split the batch into two fermenters and use this on one of them. Highly recommended!

Great results
I had not used this S-04 in a while. I use S-05 all the time and I love it. The 04 seemed to be less violent than the 05 in the starter. But it made a nice creamy starter and a great batch of English ale. I am really happy with the results.
