Omega Yeast | Oyl-430 West Coast I + | Beer Yeast | Diacetyl Knock Out Series | Double Pitch | 225 Billion Cells

• Diacetyl Knock Out (DKO) is a series of familiar house strains engineered to knock out diacetyl formation before it starts
• Lumina™ bioengineered technology develops translucent beer while maintaining parental strain behavior
• OYL-430 is a reliable, versatile and popular neutral foundation for displays of malts and hops
• Highly attenuative and moderately flocculating, it ferments crisp and clean with light citrus notes
• Double pitch size with a minimum of 225 billion cells—twice the size of the standard yeast pitch
• Proprietary propagation methods generate fresh, metabolically strong yeast cells and optimal biomass
• Omega Yeast is founded on curiosity and innovation, expertly producing common workhorse varieties and many unique strains

This ​“Chico” workhorse now expresses the ALDC enzyme, allowing you to highlight malts and hop combos without diacetyl stealing the show. Well-attenuative and moderately flocculating, with crisp, light citrus notes when fermented under 66°F (19°C).

Diacetyl Knock Out
The DKO series strains prevent the formation of diacetyl while maintaining the identical fermentation behaviors and flavor expressions of their parental strains. The benefit of ALDC-expressing yeast is that the pathway for diacetyl formation is stopped at the source resulting in virtually no diacetyl production throughout fermentation. When these strains are put to use, the diacetyl levels never reach sensory thresholds. Even when using the most sensitive GC-ECD methods, they stay at the lower limits of detection, giving you peace of mind.

Benefits:

• Avoid diacetyl hangups with hop creep
• Boost quality and keep tanks turning quickly
• Diacetyl so low, it's undetectable
• Lumina™ bioengineered technology develops translucent beer while maintaining parental strain behavior

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.
