Recommended Usage
Pitch at approximately 80–120g/hl when fermenting in the 12–15°C range. If fermenting at lower temperatures (near 9°C), increase pitch rate to 200–300g/hl. Can be rehydrated before pitching or pitched directly — this strain offers robust performance either way.
Suitable Beer Styles
- Pilsner / Bohemian Lager — delivers crispness with a refined edge
- Munich Helles / Festbier — supports malt-forward profiles with a clean finish
- Bock / Doppelbock — handles higher gravity while maintaining clarity
- American Adjunct / International Lager — neutral enough to let adjuncts or hops shine
Brewer’s Tips
- Aim to keep fermentation temperature in the 12–15°C range for best results.
- Once high kräusen is reached, raise to ~18–20°C for a short diacetyl rest.
- Lager cold for 2–4 weeks for maximum clarity and a clean finish.
- This strain’s high flocculation makes it ideal for early packaging — ensure your cold crash or lagering phase is sufficient for sediment to drop out thoroughly.
