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.
The manufacturer states the strain is directly pitchable. For activation or proofing, suspend yeast in 4 oz of warm water (85-100F). Do not stir. Let stand for 15 minutes then stir gently. Add an equal amount of wort to your solution. Cover, let sit for five minutes, and pitch.
Recommended temperature range: 64F-72F.

Used the S-05 in first brew...seemed to work well. Thought I'd try the 04, also recommended by another brewer.

Super fast
Fast, violent fermentation. Use a blow off hose, not an airlock. Flocculates quickly and completely. Will use again.

It's a workhorse
Whatever styles you're prone to brewing and yeasts that you usually use, every home-brewer should have a packet of S04 and S05 in the fridge. Great in a bind, and can work wonders for improvised brew days.

Old Product
I have been order from MoreBeer for years now instead although I have a few lhbs nearby. I like taking the time to plan out my brews online while shopping. I just received my order 6/17/16 and the yeast expires 6/16. First time I've received a near expiration yeast. This should have been on clearance. Now I need to make a beer I wasn't planning on for a couple months. Thanks

My go to dry yeast
To determine which dried yeast I preferred I brewed up 2 batches of the same beer (an ale) and pitched one with this yeast and one with safale-05. I honestly thought I would prefer -05, but the flavor profile of this yeast was better for the 2 people doing the tasting.

I use both safale yeast, 04 and -05 with direct pitching when I am out of liquid yeast and they work great and have never let me down.

Great job on English Ales
This yeast is great for brewing English milds and browns. It provides the character required for those styles. Be sure to follow the rehydration instructions from the Safale S-04 data sheet. (available under the Documents tab)
