Wyeast Brewing & Winemaking Yeast Direct Pitch Activator™ contains over 100 Billion Yeast Cells - The Direct Pitch ACTIVATOR™ contains 100% Pure Liquid Yeast plus an internal nutrient packet. This Wyeast Smack-pack™ system allows yeast metabolism to begin prior to inoculation as well as providing proof of yeast health. Our ACTIVATOR™ is designed to inoculate 5 gallons of wort with the same pitch rate recommended by professional brewers.
We also have Wyeast Private Collection yeasts listed here. Private Collections are issued 3 per quarter, and prior quarters may no longer be available. The data is maintained here for your information.
We do have a limited stock of older unsold yeasts, sold at a discounted price. While we have not had a problem building these older cultures back to viability, we recommend that you only purchase newer stock if available. Ww keep these in a separate subcategory, usually with born on dates included.
Wyeast recommends and guarantees yeasts no older than six months.
