White Labs WLP6420 Acid Tripp Yeast: Accelerate Your Sours with Complex Fruit Character
Craft Vibrant Kettle Sours with Rapid Acidification and Fruity Nuances
White Labs WLP6420 Acid Tripp Yeast is a proprietary blend developed in collaboration with Tripping Animals Brewing, designed for brewers seeking quick and complex kettle souring. This unique culture delivers balanced acidity complemented by moderate tropical (pineapple) and pomme (apple) fruit aromas, making it ideal for a variety of sour beer styles.
WLP6420 excels in rapid acidification, typically lowering wort pH from ~5.0 to ~3.5 within 12–24 hours when maintained at 105–110°F (40–43°C). This efficiency allows brewers to achieve desired sourness swiftly, facilitating timely production schedules. The strain's versatility also enables its use in diverse beer styles, including Berliner Weisse, Gose, and Sour IPAs.
