A new lab in Portland, Oregon who is making liquid yeast for both commercial breweries and home homebrewers. Each pouch boasts a whopping 200 Billion cells, providing what is considered the ideal pitch rate for five gallons of beer. This high cell count will result in a very fast start to your fermentation. A short lag time between cooling and active fermentation reduces the risk of bacteria or wild yeast taking hold. With this much yeast there is no need to make a starter in most situations. Imperial recommends that you store cold until use and then immediately pitch. Open the pouch slowly to release any potential pressure.
