Brewing Notes

GERMAN’s high flocculation is its standout practical advantage — it settles fast and thoroughly, producing brilliantly clear lager without extended cold conditioning or fining. Ferment at 10–12°C for classic clean lager character; ramp slowly to 14–15°C at the end of primary fermentation for complete diacetyl cleanup before crash cooling. One 12g sachet per 23L; direct pitch without oxygenation required.

Beer Styles & Brewing Tips

CellarScience GERMAN is the authentic Weihenstephan strain — the benchmark for traditional European lager character and the most historically proven lager culture in the world.

Best styles: Munich Helles (the definitive GERMAN showcase — let the Pilsner malt speak, keep the hops restrained, achieve brilliance through the strain’s clarifying power and neutral profile), Czech Pilsner (GERMAN performs beautifully with Saaz hops and soft water), Doppelbock (high-gravity and high-malt — GERMAN’s clean fermentation at cooler temps handles the rich grain bill without producing off-flavours or excess higher alcohols).

Australian brewing tips:

A dedicated fermenting fridge set at 10–12°C is essential for GERMAN — Australian ambient temperatures are too warm for reliable lager character without temperature control.
GERMAN’s high flocculation is a practical advantage for AU home brewers — clear lager without extended lagering or fining agents, saving weeks of tank time compared to slower-settling strains.
Pair with German noble hops (Czech Saaz, Hallertau Mittelfrüh, Spalt) for authentic European lager character; avoid high-alpha bittering hops that overwhelm the delicate malt profile.
Perform a diacetyl rest (raise to 15°C for 48 hours at the end of fermentation) before crash cooling to ensure clean, butter-free lager character in the finished beer.

In the Glass

Clean, neutral lager character with balanced malt and a dry, crisp finish. Low esters, minimal higher alcohols. Exactly what you expect from the Weihenstephan lineage — elegant, reliable, and historically proven across generations of brewing excellence.
