Safale S-04 is a very well-rounded yeast. English ale yeast selected for its fast fermentation character and its ability to form a compact sediment at the end of fermentation, helping to improve beer clarity. Safale S-04 is recommended for the production of a large range of ales and specially adapted to cask-conditioned ones and fermentation in cylindo-conical tanks.
BEERS TO BREW: English Pale Ales, English Bitters, English Milds and Browns, English IPA, Brown Porter, Robust Porter, Baltic Porter*, Foreign Extra Stout*, Dry Stout, Sweet Stout, Oatmeal Stout, English Barleywine, English Old Ale, English or American Strong Ales (Barleywines).
* Ferment on the warmer side of the temperature scale.
INGREDIENTS: Yeast (Saccharomyces cerevisiae), Emulsifier: E491 (sorbitan monostearate).
FERMENTATION: Ideally at 15-20°C (59-68°F).
PITCHING: 11.5 g per 23 L.
ATTENUATION: 75% (residual sugars 18 g/l).
TOTAL ESTERS: 37 ppm at 20°C in EBC tubes.
TOTAL SUPERIOR ALCOHOLS: 363 ppm at 20°C.
REHYDRATION INSTRUCTIONS: Sprinkle the yeast in minimum 10 times its weight of sterile water or wort at 25 to 29°C (77°F to 84°F). Leave to rest 15 to 30 minutes. Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel. Alternatively, pitch the yeast directly in the fermentation vessel providing the temperature of the wort is above 20°C (68°F). Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps. Leave for 30 minutes, then mix the wort using aeration or by wort addition.
STORAGE: 36 months from production date. During transport: The product can be transported and stored at room temperature for periods of time not exceeding 3 months without affecting its performance. At final destination: Store in cool (< 10°C/50°F), dry conditions.
SHELF LIFE: Refer to best before end date printed on the sachet. Opened sachets must be flushed sealed and stored at 4°C (39°F) and used within 7 days of opening. Do not use soft or damaged sachets.
