Fermentis SafLager™ S-23 2.5kg

SafLager™ S‑23 is a bottom‑fermenting yeast originating from Berlin, recommended for producing fruitier and more estery lagers. It delivers beers with a pleasant length on the palate, particularly suited to modern and hoppy lagers.

This strain stands out with an apparent attenuation of 80–84%, high flocculation and fast sedimentation, which helps achieve natural beer clarification. It performs best within 12–18 °C, with the option to ferment lower by increasing the pitching rate.

This professional 2.5 kg format meets the needs of craft and industrial breweries seeking a reliable, stable and high‑performance lager yeast for large‑volume production.

Why choose this product?

• Fruity and estery profile for modern lagers with more character.
• Fast sedimentation and high flocculation for excellent clarity.
• Strain suited to hoppy lagers and more expressive aromatic profiles.

Technical Tips

• For cleaner lagers, ferment around 12–14 °C and plan an extended cold conditioning.
• Below 12 °C, increase the dosage (up to 200–300 g/hl at 9 °C) to avoid slow fermentations.
• For direct pitching, sprinkle evenly over the wort to reduce clumps and optimise viability.

Technical FAQ

• Is this yeast suitable for classic neutral lagers? It is better suited to fruitier, more estery lagers; for a very neutral profile, choose another lager strain.
• Can it be used for heavily hopped lagers? Yes, its fruity profile pairs well with modern aromatic hopping.
• Can it be pitched without rehydration? Yes, the E2U™ certification allows direct pitching.
• How long can an opened bag be stored? Up to 7 days at 4 °C, tightly sealed.
