This is the long sought after pacman yeast from a very popular brewery in Newport, Oregon. Homebrewers rave about the clean ferment this yeast provides for all ales. This strain has a wide range of temperature threshold from 55F-78F. We recommend fermenting at 64-66F for the ultimate experience. Do I need to make a starter for an Activator? No. The Activator is designed to deliver professional pitch rates (6 million cells/ ml.) when directly added to 5 gallons of wort. ( <1.060 at 70 degrees). However, if a package is slow to swell, suspected of being mishandled, or if the date is approaching the six month shelf life it is a good idea to build the culture up with a starter. High gravity or low temperature fermentations require higher pitch rates. This can be achieved with inoculating with additional packages or making a starter. Please note that wy1764 has been known to bloat when shipping due to the yeast "off-gassing". Please put this yeast in your refrigerator when received, as the yeast will be fine and should still be viable.
