Safale S-04 English Ale Dry Yeast

Brew smooth, well-balanced ales with SafAle S-04, a fast-fermenting English ale yeast known for subtle fruity and floral character with a clean finish. This reliable strain produces clear, approachable beers with consistent results, making it a staple for a wide range of ale styles.

SafAle S-04 is intended for brewers seeking dependable fermentation with restrained ester expression and strong clarity. Its balanced profile supports malt-forward and hop-balanced beers alike, making it suitable for styles such as pale ales, porters, stouts, and bitters.

This dry ale yeast features high flocculation, allowing yeast to settle quickly and produce a bright finished beer. It performs best within a fermentation temperature range of 64 to 79 degrees Fahrenheit. Each 11.5 gram packet is suitable for fermenting approximately 5 to 8 gallons of beer, depending on wort gravity and pitching practices.

For best results, rehydrate the yeast prior to pitching and maintain stable fermentation temperatures within the recommended range. Adequate oxygenation at pitching helps promote fast starts and clean attenuation.

Widely used by home and professional brewers for reliable ale fermentation, SafAle S-04 delivers consistent performance and smooth, well-rounded flavor development across many classic ale styles.
