More Yeast With a minimum of 100 billion cells per package, the 125 ml Activator™ from Wyeast has the highest cell count of any ready to pitch fresh 100% Pure Liquid Yeast™ product on the market.
Built-in Activation The Wyeast Smack Pack™ is the only package on the market that provides proof of yeast activity before use. You know the yeast is active before it goes into your wort.
Ready to Pitch The 125 ml Activator™ is ready to pitch immediately, or for an added boost, activate the yeast when you start brewing and pitch it in its active state by the time the wort is cool. The Activator™ gives the brewer options no other package can deliver.
Faster Starts You will achieve faster starts with the Activator™ because of the high cell count and the fact that the yeast is active when it hits the wort. When yeast is active, sugar is already being transported across the cell membrane which greatly reduces lag time.
Longer Shelf Life The Activator™ package was designed with superior UV light- and oxygen-barrier material to extend shelf life, making our 6 month from manufacture date Product Warranty possible. Yeast slowly depletes energy reserves while in storage. The nutrient pouch inside the Activator™ helps the stored yeast recover from dormancy and restores vitality.
* Wyeast Direct Pitch Activator™ packages will sometimes swell slightly, or moderately during shipping or later while properly stored. This is not an indication of deterioration if the package is less than 6 months old and has been properly handled. This is result of trace amounts of nutrients, still available at the time packaging, causing small amount of culture activity and CO2 production. Some strains are more prone to this than others.
