Safale S04 Beer Yeast 500g pack

Fermentis dry brewing yeasts are well known for their ability to produce a large variety of beer styles.

In order to compare our strains, we ran fermentation trials in laboratory conditions with a standard wort for all the strains and standard temperature conditions (Saflager: 12°C for 48h then 14°C / Safale: 20°C). We focused on the following parameters: Alcohol production, residual sugars, flocculation and fermentation kinetic.

Given the impact of yeast of the quality of the final beer it is recommended to respect the recommended fermentation instructions. We strongly advise users to make fermentation trials before any commercial usage of our products.
