  • S-04 produces fruity and floral notes and is ideal for a large range of American and English Ales
  • A fast fermenting, highly flocculent strain that tends to produce beers with higher clarity
  • Fermentis active dry yeast offers reliability, ease-of-use, and consistency to home and professional beverage makers across the world

Homebrewers love this commercial English Ale yeast for its big, clean flavor; its rapid fermentation; and its highly flocculant character.

Widely recommended for practically any American or English style beer, S-04 yeast a rapid starter and finisher which settles out extremely well, leading to a clean finished beer. Great to keep a few packets as back-ups or just to use as a less-expensive alternative to liquid cultures.

This yeast can be pitched directly, but if you prefer to rehydrate, the instructions are below.

Sprinkle the yeast in a minimum of 10 times its weight of sterile water or wort (we suggest 4 oz) at 70°F to 77°F (21 to 25 °C). Do not stir. Leave to rest 15 to 30 minutes. Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.

  • Attenuation: 74-82%
  • Sedimentation Time: Fast
  • Alcohol Tolerance: 9-11% ABV
  • Optimum Fermentation Temp: 64-78°F

*See the technical data sheet below for more information on rehydration, usage and storage.

What is the alcohol tolerance of this yeast? I didn't see it mentioned on the TDS.
Mark on Dec 23, 2019
BEST ANSWER: While I don't know exactly, #04 is my goto for fermenting dry, double digit abv. I actually find it to ferment cleaner than #05, better fluctuation, and denser yeast cake.

worked great with Irish Red Ale
I fermented under pressure at 8 psi and it worked great. FG flatlined after only two days! I let it go for another day just to be sure. Result was very successful batch. I am a convert to pressure fermentation.

Worked great
This was my first time using dry yeas and I was very happy. The lag time to fermentation was short and my beer tasted the same as when I was using Liquid yeast.
