Fermentis - SafAle™ S-04 SafAle Dry Ale Yeast - 11.5g
Fermentis SafAle™ S-04 - English Ale dry yeast
The yeast Fermentis SafAle™ S-04 is a top-fermenting dry yeast of English origin, known for its balanced, slightly fruity, and typically ale-like aromatic profile. Highly appreciated for British-inspired beers, it helps highlight the malty character while adding a pleasant fruity touch and excellent clarification.
Thanks to its strong flocculation, SafAle S-04 quickly forms a compact sediment, helping produce a clearer beer. Its fermentation profile makes it a particularly versatile yeast for English ales, as well as for several modern styles where more character is desired than with a very neutral American strain.
SafAle S-04 profile
S-04 is known for developing a slightly fruity fermentation character that complements malt, caramel, biscuit, and roasted grain flavors very well.
Its strong flocculation ability is also one of its distinctive characteristics. It tends to produce a beer that clears effectively after fermentation, making it particularly interesting for traditional British styles.
Compared with a neutral American yeast such as SafAle US-05, the S-04 generally provides a more expressive fermentation character with a greater emphasis on fruity esters.
