Smack-Pack Activator System™
Activator™ Product Information and Usage
Activator™ packages are designed for direct inoculation of 5 gallons of standard gravity ale wort. Activator™ Wild & Sour packages contain live yeast or bacteria cells in a liquid slurry. This yeast slurry is packaged in an optimum condition for storage, while maintaining the ability for rapid and complete fermentation.
The Activator™ is designed to directly inoculate 5 gallons of standard strength ale wort (1.034-1.060 SG) with professional pitching rates. For lagers, we recommend inoculating the wort at warm temperatures (68-70°F/ 20-21°C), waiting for signs of fermentation, and then adjusting to the desired temperature. Alternatively, for pitching into cold conditions (34-58°F/ 1-14°C) or higher gravity wort, we recommend increasing this pitching rate. This can be achieved by pitching additional Activator™ packages or by making a starter culture. Please see the Pitch Rate section for additional information.
Sterile Packaged Product – UV Light Barrier – 100% Guaranteed Pure
Keep Refrigerated. Do not freeze.
Best if Used by: This package is best when used within 6 months of the manufacturer’s date when stored between 34-40°F (1-4°C). Older yeast or yeast that has been exposed to higher or lower temperatures may take longer to become active or swell.
Our Product Warranty states that we guarantee the viability of the yeast in our Activator™ packages for 6 months from the manufacture date assuming that they have been properly shipped, stored and handled. Our superior packaging material provides 100% oxygen barrier and UV light protection making this exceptional guarantee possible. During this 6 month guaranteed shelf life, some loss of viability is to be expected. This will vary from one strain to another. Activator™ packages that are 4 months old or older may require additional time to swell after activation.
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.
We think you’ll agree our unique “Smack Pack” is preferable to all other liquid yeast packaging options to assure the success of your fermentations.
