The Brewer’s Edge Mash & Boil with Pump is a single vessel, electric brewing system that lets you mash up to 16 lbs. of malt and boil up to 7.5 gallons with hardly any footprint. An internal sparging basket allows you to easily lift the grain out of the boiler, letting you mash and boil in just one vessel. The adjustable digital thermostat can display reading in either Fahrenheit or Celsius and features an adjustable run timer, preset at 3.5 hours for safety.
