One interesting feature of the Cona brew boards is that the butane burner effectively “pins” the brewer in place on the board. Plus, the Cona base itself doubles as a funnel holder. This prototype for a brew board for a Japanese-style siphon provides these same features. An exact footprint for the brewer is routed out in the board, to secure the brewer for storage or transport. Plus, a stand pipe (with a drip catcher in the bottom) provides a convenient funnel holder. CoffeeBOS is in the process of designing additional production brew board models for common Japanese siphons (Hario & Yama).
