Delter Coffee Press – Grey is the first coffee maker designed from the ground up, to solve one of the biggest coffee brewing problems-agitation. Uncontrolled agitation results in bitter coffee and inconsistent extraction. Delter’s unique Jet-Seal keeps the brew water and coffee grounds separated preventing uncontrolled agitation. Water contact is activated by actuating the Jet-Seal with pressure, offering complete control over water flow and agitation. The result is an exceptional cup like no other. Less bitterness with more clarity.
A unique delta Jet-Seal separates the brew water and coffee – stopping unwanted agitation and offering next-level brewing possibilities. The Delter Coffee Press is the first coffee maker to use a process we call “Injection Brewing“, a completely new brew method we developed after countless hours of experiments. This works by infusing hot water into the coffee grounds under pressure, for improved control and consistency.
