For over 30 years, the Wyeast Activator™ is the only product that "proofs" the yeast and shortens lag time when it hits your wort. Activator™ packages include a sterile liquid nutrient pouch that, when smacked, releases its contents into the yeast slurry. The available sugars and nutrients initiate the culture’s metabolism which in turn generates CO₂ and causes swelling of the package, serving as a viability and vitality test as well. Although beneficial, cultures do not need to be activated prior to inoculation.
Species: Saccharomyces cerevisiae
Profile: Very clean, crisp flavor characteristics with low fruitness and mild ester production. A very versatile yeast for styles that desire dominant malt and hop character. This strain makes a wonderful "House" strain. Mild citrus notes develop with cooler 60-66F (15-19C) fermentations. Normally requires filtration for bright beers.
All liquid yeast purchased from Oregonized Brewing will ship with an ice pack. Additionally, we ship all of our liquid yeast USPS Priority as slow shipping won't be doing your yeast any favors, just off-flavors.
