Custom balance of system (BOS) components for espresso and coffee brewing. Why brew bored?

When I started nerding out on siphon brewing, I decided that I wanted some "balance of system" (BOS) components to get the convenience and control that I wanted. With the help of my neighbor, Aldo Valdez Bohm, a woodworker and artist, I designed several siphon brew boards for home use. I am offering the Cona brew boards through Etsy so that other home baristas and coffee aficionados can optimize the brewing potential with this beautiful brewing system. All brew boards are built by Avalbo Industries ( I receive them in the raw, sanded through 220 grit, then sand them through 300 or 400 grit, depending on the surface, and apply the oil and wax finishes. The NEWD 49mm portafilter for Olympia Cremina and Elektra MCAL espresso machines are designed and manufactuered by Richard Penney. For more info check out the CoffeeBOS website:
