CellarScience - MATTERHORN Light Lager Yeast x 15g

MATTERHORN: The Crisp, Clean Light Lager Yeast

MATTERHORN is a top choice for everyday light lagers that define a brewery’s baseline. Derived from a classic Swiss-origin strain, this yeast delivers crisp, well-attenuated beers with a minimal fermentation signature. With high cell counts in every 15g sachet and dependable performance, MATTERHORN provides professional-grade reliability for craft and home brewers seeking exceptional clarity, malt definition, and hop expression.

🍺 Styles & Flavour Profile: Subtle Fermentation with Aromatic Lift

MATTERHORN provides a restrained, neutral background that allows your grain bill and hop selection to take centre stage. Its fermentation character remains delightfully subtle, contributing a light floral quality that adds aromatic lift without competing with delicate malt or hop character. Combined with its attenuation profile, MATTERHORN produces a firm, dry finish that prevents malt-forward grists from becoming overly heavy.

Ideal for a Wide Variety of Lager Styles

MATTERHORN’s versatility and crisp finish make it perfect for a broad range of traditional and modern lager beers:

• German & Czech-Inspired Pilsners
• Everyday Light Lagers
• Modern Hoppy Lagers & West Coast Lagers
• Full-Bodied Lager Grists (where a dry, refreshing finish is desired)

Packaging & Dosage

One sachet is enough to treat a single 19-23L batch.

When calculating for larger batches, use at a rate of 0.5-1g per Litre. We recommend rounding up by one full sachet rather than measuring out the yeast exactly.

Calculation for Larger Batches

• Use at a rate of 0.5-1g per Litre (approx. 50-100 g/hL).
  
• For high-gravity ales or exceptionally bright beer, increase toward 2–3 g/L
