Safale S-04 English Ale Yeast - Fermentis

Safale S-04 English Ale Yeast - Fermentis

Please select from the following option(s) to see pricing and availability.

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.
Recommended temperature range: 64F-72F.
*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 Lashway on Dec 23, 2019
BEST ANSWER: At least 8% - because that's what my imperial stout came out as. This is a pretty great yeast. It's crazy fast (control ferm temps) and the yeast cake clarifies into concrete at the bottom of the fermenter. Mostly I use US-05.

Dry Yeast FTW
After 8 years of brewing, I've been going back to dry yeast, this is one of my go to yeast strains. Gets to work quickly and finishes super clear.

Fast and Clean!
To those new to brewing, play it safe with Safale S-04. Don't worry about hydrating, pitch it dry and stir it in. It works fast and clears out fast. I typically get crystal clear ale in 4 days with this stuff. I've tried several and keep coming back to this one. I brew 3 gallon batches on the stove top, use 1/2 pack, tape it shut and use the rest within a couple weeks with no problems.
Fast and clean!

Always keep some on hand.
Mostly use liquid yeasts with a yeast starter. Always like to keep a couple of varieties of Safale dry on hand. Easy to store and lasts a long time. Handy to have in case of a yeast emergency.
