Brewer notes

SafAle S-04 is a dry ale culture from Fermentis (S-04). Fermentation character can show clean and crisp notes. Choose it when its fermentation profile fits the intended beer rather than substituting by attenuation alone. Reference guidance: attenuation guidance 71–75%, fermentation range about 15–24°C (59–75.2°F), alcohol tolerance around 10%. Treat temperature, attenuation and alcohol tolerance as strain guidance; wort composition, pitch health and fermentation management still affect the result.
