This document provides instructions for building the Brutus 20E, a 2-vessel brewing system designed for counter top use. It consists of an electric kettle, mash tun, and "magic box" with permanently plumbed counterflow chiller and pump. The system aims to automate and improve the brewing process over batch infusion methods while keeping the setup compact. Details are provided on building each component, including necessary fittings, as well as lessons learned around pipe fitting standards and availability.
