Safale S-04 English Ale Yeast 11.5g

SafAle S-04 English Ale Yeast

SafAle S-04 is a fast-fermenting English ale yeast that produces balanced fruity and floral notes. Its strong flocculation helps the yeast settle quickly after fermentation, making it a useful choice for clear, traditional ales and cask-conditioned beer.

It suits a wide range of British and American ale styles, from bitters, milds, porters and stouts to pale ales and hop-forward beers where you want some fermentation character without strong phenolic flavours.

How to Use

Substitutes

Mangrove Jack's M36 Liberty Bell is a good alternative when you want a fruity British-style ale profile.

LalBrew Nottingham is cleaner and generally finishes drier, making it a better alternative when you want less ester character and a crisper finish.

Brewer's Tip

S-04 is a strong flocculator, so it is particularly useful when quick settling and good beer clarity are priorities.
