Activator™ packages are designed for direct inoculation of 5 gallons of standard* wort. Activator™ packages contain live yeast 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.


Activator™ packages include a 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.


Usage
The Activator™ package contains a minimum of 100 billion cells in a yeast slurry.. 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.


Instructions for the proper use of Activator™ packages:
To Activate, locate and move inner packet to a corner. Place this area in palm of one hand and firmly smack the package with the other hand to break the inner nutrient packet. Confirm the inner packet is broken. Shake the package well to release the nutrients. Allow the package to incubate and swell for 3 hours or more (it is not necessary for this package to fully swell before use) at 70-75°F (21-24°C). Use sanitizing solution to sanitize the package before opening. Shake well, open and pour the Activator™ into 5 gallons of well aerated or oxygenated wort up to 1.060 OG at 65-72°F (18-22°C). Maintain temperature until fermentation is evident by CO2 bubble formation, bubbling airlock or foaming on top of wort. For high gravity or low temperature fermentations additional yeast may be required. 6. Adjust to desired fermentation temperature.
Full swelling of Activator™ packages is not required for their use. The contents of Activator™ packages may be direct-pitched without prior activation. Our smack pack technology is intended to be a tool for your use in determining viability, and in initiating metabolism for faster starts to fermentation.


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. If it is more than 6 months past the manufacturer's date, we suggest you do a yeast starter to rebuild the yeast cell count.


Regarding the manufacturer's dates on liquid yeast: We sell liquid yeast past the "Best Before" date at a discount. The discount will be applied when your card is charged and will not show up in the cart during checkout. Please call us if you would like to confirm the date.
