Jeff started brewing 5 litres of microbes on the kitchen table in 2009 and testing it on friends and family. Proving a success, he expanded his operation, developing and refining his brewing technique, to produce 11 gut health supplements. Now microbz is made in a 6000 sq ft factory and is widely sold throughout the UK. More recently he is working with the UK agriculture sector to provide microbes as part of a regenerative farming solution.
