Vintner's Choice Activator™

Wyeast Laboratories, Inc. Activator™ packages are designed for direct inoculation of 5 gallons of must or juice.

The Smack Pack System™ provides optimum conditions for storage, while providing proof of healthy yeast ready for inoculation of must of juice.

Activator™ packages include sterile liquid nutrient pouch that, when “smacked”, releases its contents into the yeast slurry and “activates” the package. The available nutrients initiate the culture’s metabolism which in turn generates CO2 and causes swelling of the package. This process will reduce lag times by preparing the yeast for a healthy fermentation prior to inoculation. Activation also serves as a viability test of the culture. Expansion of the package is an indicator of healthy (viable and vital) yeast. Although beneficial, cultures do not need to be activated prior to inoculation.

Malolactic Cultures

Malo-lactic Cultures Product Information and Usage

Wyeast Laboratories, Inc. Malo-lactic Cultures are designed for direct inoculation of 5 gallons of wine.

Malo-lactic Culture packages contain a live liquid suspension of Oenococcus oenii grown in a sterile organic juice based nutrient medium. Malic acid reduction will balance and soften wine while enhancing flavor and aroma characteristics including vanilla and buttery notes. 4007 Blend (blend of ER1A and EY2d cultures) will provide rapid and complete malic acid reduction in wine over a broad spectrum of conditions.
