Leon Hussey was the next to develop

Leon Hussey was the next to develop a tea machine that works well, maintaining aeration and excellent organism growth in the tea. The 5 gallon “Keep-It-Simple” machine makes excellent tea in 12 hours. It is nearly impossible to overwhelm this tea machine with too much food resource, and as a result, E. coli will almost never grow in the tea. Only a combination of high foods and really poor compost will result in the tea having E. coli above acceptable levels. The Simplici-tea company which makes the KIS brewers, has added a 30 gallon machine. These machines use air bubblers to produce the tea, blowing air into the tea, which causes mixing through the compost, with adequate extraction of the organisms and foods from the compost.
