WLP830 German Lager Yeast is a classic, workhorse lager strain known for producing clean, crisp beers with a smooth, well-rounded finish. It is widely used for traditional German-style lagers and is flexible enough to perform beautifully across most lager families – from bright, snappy pilsners to rich, malt-forward bocks.

This strain ferments clean with a subtle hop accentuation, helping noble hop character stay elegant and focused while still letting malt structure come through. With medium attenuation and medium flocculation, WLP830 tends to produce balanced lagers that are crisp without feeling thin and malty without becoming heavy.

Highlights

• Clean, crisp profile with light hop accentuation
• Extremely versatile lager strain
• Reliable performance across nearly any lager style
• Balanced attenuation and flocculation for a smooth, well-rounded finish
• PurePitch® Next Generation packaging for consistent, reliable pitching

Brewing Notes

• For best lager character, ferment cool and steady within the recommended range, then raise temperature briefly near the end of fermentation for a diacetyl rest if needed.
• Proper oxygenation and a healthy pitch rate are especially important for lagers and help promote clean fermentation and strong attenuation.
• After primary fermentation, a cold lagering period improves clarity and refines the finish – longer lagering is often beneficial for higher-gravity styles like bock and doppelbock.
• Medium flocculation typically clears well with time and cold conditioning, and can be helped further with finings if desired.

Storage and Handling

• Store refrigerated until use.
• Allow the pouch to warm slightly toward fermentation temperature before pitching to reduce temperature shock.
• Use an appropriately sized starter or increased pitch rate for lagers and/or higher-gravity wort as needed for your process.
