SCB runs on two brewing systems.
The indoor unit runs on a 5 gallon electrical system that is vented to the outside.
A homemade electronic regulator for the pump, heating element and wort temp.
Homemade yeast starter.
A counter-flow chiller can quickly drop the temperature of boiling wort to yeast-pitching tolerances.
A fancy new mash recirculator.
And a grain grinder, using lithium drill batteries as a power source.
