Description

This yeast is used to make American style lagers. Dry and clean with a very slight apple fruitiness. Sulfur and diacetyl production is minimal.

  • Optimum Fermentation Temp: 50–55°F
  • Attenuation: 75–80%
  • Flocculation: Medium
  • Alcohol Tolerance: Medium (5–10%)
  • Cell Count: 100+ Billion

Brewing Tip: We Recommend you make a yeast starter for all lagers. Because of the cold environment you will need about 4 times as much yeast to successfully ferment a lager. If you don't have a yeast starter pitch 2-4 vials at 60-70°F and cool to 48-52°F within 12-18 hours. To ferment lagers like the German's and Czech's make an active starter of 2000ml per 5 gallons. Pitch at 45-48°F and let it naturally rise to 48-52°F. Hold your fermentation at 48-52°F for 4-6 weeks in the primary. A diacetyl rest is recommended after the last week of fermentation. Raise to 55-58F for 3-5days and crash to 40F. It is normal if lager fermentation takes 3-4 days to show any sign of krausen after pitching yeast.

Use this yeast in: American Lager, American Light Lager, Bohemian Pilsner, Marzen, Munchen Helles, Munchner Dunkel, Munchner Dunkel, Schwarzbier, Vienna Lager.

Please Note: For best results we Always recommend ordering an Ice Pack with your liquid yeast. Ice Packs can be found below in the "You might Also Need" section.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Nice yeast
I use this yeast regularly, one vial per 5 gallons, for excellent low gravity lager.
