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.

I use this as my go-to yeast for hoppy ales
David S on Jul 26, 2021
Safale yeast surprised me. I thought dry yeast wasn't that great, but I used this on my brew store's recommendation. I sprinkled it directly onto the wort with no starter and even then had really great results.

What is the alcohol tolerance of this yeast? I didn't see it mentioned on the TDS.
Mark 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.

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.

Perfect for my Recipe
I use this for most of the ale that I brew and recommend it for any English style ale, such as amber or stout. Lag time is about 4 hrs and it completes within 4-5 days. it attenuates nicely. I tried liquid yeast and found that the lag time is much longr (up to 12 hrs or more.) I do switch to CALI for American style cream ales of summer wheat and to lager yeast for lagers, but I use this for everything else.

Good yeast
Fermented a 1.065 wort down to 1.012 in less than 72 hours. Good yeast. At higher temp ranges I notice some citrus notes.

Great Yeast
The dry yeast is superior to any of the liquid yeasts. The liquid yeast arrive with very few live yeast cells. The dry yeast starts up very quickly and finished strong.

Might try some liquid yeast when the weather gets colder.

Great Product, Interesting Shippong Choice
When I got this package, it came in a HUGE box. At first, I thought that it was 10 whole pounds of malt, but when I opened the box, I saw that it was the small 11 gram bag of these yeasts! I thought it was really funny how they chose to ship it! :). Evererything came as expected thoguth, so I have no complaints whatsoever.
