Cool that this worked - but no, not really - miracles happen when superstition defeats physics.
This was just simple, crude physics realizing that water doesn't compress like steam. The Brewtus has exceeded our expectations - with minor E61 tweaking and fresh thermal grease on the thermocouple - it gives consistently tasty pours from commercial beans, which is an inspiration to haul out the Gene Coffee and resume roasting again. Cheers Jim Water is infinitely less compressible than steam - just given it an escape route. On Fri, Nov 13, 2020, 12:43 James Williamson <[email protected]> wrote: > Ok Jim.
