Brewer notes

Alt is a liquid ale culture from Omega (OYL-001). Fermentation character can show clean notes. Choose it when its fermentation profile fits the intended beer rather than substituting by attenuation alone. Reference guidance: attenuation guidance 73–77%, fermentation range about 13–20°C (55–68°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.
