Fermentis SafAle S-04 English Ale Dry Yeast – 11.5 g

Fermentis SafAle S-04 is a fast, dependable dry English ale strain for brewers who want strong flocculation, good malt presentation, and a fermentation profile that works well in classic British styles as well as many everyday ales. It is a practical choice for bitters, milds, porters, stouts, brown ales, and other recipes where clear beer, rounded malt character, and efficient fermentation all matter.

This 11.5 g dry yeast is known for its quick start, compact sedimentation, and lightly fruity profile. With a published working range around 59 to 72°F, attenuation around 74% to 82%, and high flocculation, S-04 is especially useful when you want beer to clear quickly while still retaining a classic English-leaning fermentation character.

Why Brewers Like S-04

• Fast, reliable fermentation: Helpful for efficient ale production and predictable turnaround
• High flocculation: Settles compactly and supports clearer finished beer
• Balanced English character: Mild fruit and solid malt support without overwhelming the recipe
• Useful dry format: Easy to stock for regular brew days and backup yeast needs

Best Fit Beer Styles

• Mild, porter, and stout

• Scottish-style ales
• General-purpose ales where quick clarification is a plus

Practical Brewing Notes

SafAle S-04 is a good fit when you want a beer to finish with clear structure and firm malt definition rather than a highly expressive ester profile. It is especially handy for pub-inspired recipes and dependable house ales where repeatability matters.

Because this is dry yeast, it is generally less risky to ship than liquid yeast. It still makes sense to avoid excessive heat and long transit exposure whenever possible, especially during warmer parts of the year.
