Ex aerospace engineer (electronics) with Bae sytems. Ex Royal Air Force, served on 74, 11, and 43 squadrons.
Did my first homebrewing about 40 odd years back, using the Beersphere which I had to modify to get repeatable and successful results. (gas leaks, gas leaks ... ! )
Got back into brewing with the current conditions being in place (no pubs ). Have a shiny new King Keg, a brew in, and clearing now :) Can already see it needs a few crucial modifications, those will have to wait for now.
