The Delter Coffee team invented a unique multi-layered drip tray with pin hole drain that will drip automatically creating a nice strong coffee without any compromises.
How? It's actually really simple. Each tray is shallow, which means that there is minimal pressure loss as the water level changes. But more importantly, because each tray drips simultaneously, the bottom tray that drips over the coffee remains full, meaning the drip rate over the coffee remains steady, and is constant right up until the higher trays are completely emptied out.
The system brews in 3-4 hours to ensure fresh cold drip coffee in a convenient time frame.
