Blending WL001 and WL002 Right in the Vial
Best of Both Worlds yeast blend came about after we asked our friends at White Labs if the two strains could be blended right in the vial. They told us it was possible (and they even liked the idea!) so we began working on a final formula. Because English tends to dominate just a little, we lowered the percentage of English and raised the percentage of California in the final blend.
The Flavors and Fermentation Characteristics
What we found in our years of blending at the tap holds true - you can expect the malty flavors and aromas of English combined with the ability of California to highlight hops. The true bonus of blending the strains prior to fermentation was discovered in a test at White Labs. The California strain will ferment more sugar than English and that holds true in the blend so your beers will have a higher attenuation (less malt sugar left in beer). Conversely the blend had the same level of flocculation (ability to clump and drop out of solution) as English, naturally leaving a clear beer after fermentation. The English yeast cells apparently also help drop the California yeast cells out of solution. The end result is a yeast blend that has the awesome flavors of the two best selling yeast of all time with the attenuation of California and the flocculation of English.
For best results we always recommend ordering an ice pack with your liquid yeast.
