This is a replacement for the Air Still ingredient pack that was discontinued, the only difference is it doesn't come with the carbon filters. We have these as an add on for your convenience please see option below, they come in a pack of 10. For use with the Air Still and companion pack system. Contains enough turbo carbon, yeast, nutrients and turbo clear to produce 10 Liters of wash (doesn't include sugars) for distilling through the Air Still system. You can add 5 lbs. of corn sugar which is enough to do 1 batch of wash.
