CellarScience® MATTERHORN Dry Yeast | Light Lager | Premium Beer Yeast

• MATTERHORN is a top choice for everyday light lagers that define a brewery’s baseline
• Delivers crisp, well-attenuated beers with a minimal fermentation signature
• Designed to be sprinkled directly onto the surface of your wort with no pre-oxygenation before pitching required
• Ferment between 48-58°F

MATTERHORN is a Swiss-origin lager strain particularly well suited to light lagers and other styles where clear malt and hop definition is important. Its fermentation character remains subtle, with a light floral quality that adds aromatic lift without competing with the malt or hops. Combined with its attenuation profile, MATTERHORN produces a firm, dry finish that keeps delicate malt character and hop bitterness clearly expressed.

That makes MATTERHORN particularly useful for German or Czech-inspired Pilsners, everyday light lagers, modern hoppy lagers, and West Coast Lagers. It can also work well with richer wort grists when the goal is to maintain a dry, refreshing finish and prevent malt character from becoming overly heavy. Its consistent performance across its recommended temperature range provides the reliability and repeatability needed for both traditional and modern lager production.

• A top choice for everyday light lagers that define a brewery’s baseline
• Direct Pitch: No rehydration needed
• Reliable & Consistent: Every batch undergoes PCR testing for purity and performance
• High Cell Count: 15g per sachet — over 36% more than standard 11g dry yeast packs

Dosage:
One sachet is enough to treat a 5–6 gallon batch. When calculating for larger batches, use at a rate of 2–3 grams per gallon of wort. We recommend rounding up by one full sachet rather than measuring out the yeast exactly.

For professional brewers, use at a rate of 90-170 grams per barrel, depending on wort temperature and gravity.

Optimum Fermentation Temp: 48-58°F
Flocculation: Medium to High
Alcohol Tolerance: 12% ABV
Attenuation: 79-83%

CellarScience Yeast:
For years liquid yeast has been sold as the higher quality option but times are changing. Yes, 20 years ago dry yeast was made by bread yeast producers and the quality was not as good as liquid yeast. CellarScience is helping to flip that script with a full lineup of high-quality dry yeasts. Cell count and viability is usually higher than commercial liquid yeast pitches, which vary from pouch to pouch and don't ship well. CellarScience yeast can be pitched directly in most batches of wort, offering significant time savings. Yeast that is quick and easy to use, high quality, and available at a reasonable cost adds up to a tremendous value. Quality yeast that doesn't "break the brink".

CellarScience Nutrients:
For high gravity ferments consider rehydrating yeast with CellarScience FermStart yeast hydration nutrient. For high gravity or low nutrient wort, feed your fermentation with CellarScience FermFed DAP Free complex yeast nutrient mix.
