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.
