Cold drip coffee with no valves, no adjustments, and no babysitting. The Delter Cold Drip is a valveless cold drip coffee maker that automatically maintains a consistent drip rate of approximately one drop per second — no manual flow adjustment required. From the same Brisbane team behind the Delter Coffee Press, the Cold Drip was designed to fix the biggest problem with traditional cold drip systems: inconsistency. Brew 600ml of smooth, low-acidity cold brew in 3 to 4 hours and enjoy it across the week. Say Goodbye to Valves Every cold drip brewer before this one used a valve to control the drip rate. And valves have always had one fundamental problem: they stop, drift, and need constant adjustment. The Delter Cold Drip takes a different approach entirely. Its unique multi-layered tray system uses precision pinhole drains to automatically maintain your drip rate. Because each tray drips simultaneously, the bottom tray that drips over the coffee stays full, keeping the rate steady from start to finish. Set it up and walk away. Key Features Fully Automatic Drip Rate Precision pinhole drains maintain approximately one drip per second automatically. No valve, no monitoring, no adjustment needed. 600ml Capacity — Up to 5 Servings Brew on the weekend and enjoy a serve every day through the working week. Each batch yields up to 600ml of cold brew concentrate, ready to serve over ice, with milk, or straight. Brews in 3 to 4 Hours No overnight wait. Cold brew is ready in an afternoon — set it up in the morning and it's done before lunch. Reusable Stainless Steel Filter A 304 stainless steel fine mesh filter eliminates sediment from the final brew without the ongoing cost or waste of paper filters. Low Acidity, Naturally Smooth Cold drip brewing produces coffee with lower acidity than hot-brewed methods — easier on the stomach, naturally sweeter, and without the harshness of over-extraction.
