Omega OYL-605 Lactobacillus Blend for Clean, Controlled Kettle Souring
Omega Yeast OYL-605 Lactobacillus Blend is a souring culture for brewers who want bright lactic acidity, clean tartness, and strong control in kettle sour and mixed fermentation workflows. This blend combines Levilactobacillus brevis and Lactiplantibacillus plantarum, making it a practical choice for Berliner Weisse, Gose, kettle sours, and other beers where acidity is built deliberately before or alongside primary fermentation.
Based on current technical references tied to this product, the blend performs across a broad temperature range of 68 to 95°F and is commonly used for souring windows of roughly 24 to 72 hours. It is also highly hop sensitive, so brewers should plan souring in low- or no-IBU wort when they want reliable lactic acid production.
What OYL-605 Contributes to Beer
- Clean lactic acidity: Helps produce bright sourness without heavy funky overlap
- Good process control: Useful for brewers building acidity in a deliberate, repeatable way
- Kettle sour flexibility: Strong fit for Berliner Weisse, Gose, and modern sour beer bases
- Blend advantage: Combines two established souring organisms for practical souring performance

Liquid Culture Storage and Shipping
We store liquid cultures in temperature-monitored refrigeration to help protect culture health until shipment. Once in transit, weather and carrier handling are outside our control, so customers should choose shipping protection based on season, destination, and transit time.
Expedited shipping, insulated mailers, and ice packs can materially reduce risk for liquid cultures during warm-weather transit.
