Capacity from 30 to 250 gallons
Garden writer, Jeff Lowenfels was our first purchaser. Jeff slid the 250 gallon Bob's Brewer into his golf bag and carried it on the plane, in the overhead, as he flew back to Anchorage, Alaska. When Jeff heard the quiet percolator sounds of the brewer he insisted we call it "BobOLator"...and so it is!
The BobO takes about 10 times the amount of compost and nutrients as the Bitti and produces a minimum of 30 to a maximum of 250 gallons. The BobO system is nearly silent.
