The Delter Coffee Press produces super clean, flavourful coffee which no other hands on maker can rival. Although it resembles some other brewers, and has much in common in execution, the Delter has something a little extra. It is the only manual brewer that is designed to minimise ‘agitation’. This describes the interaction between the grounds and the water. Agitation occurs when water is forced through the grounds: too much agitation can cause a bitter, over extracted brew, even with very short brew times. The Delter seeks to control the amount of agitation with what they call ‘injection brewing’. When pressure is applied, the jet filter comes into play, ‘injecting’ the water steadily and managing agitation. And the proof is in the pudding: the Delter produces a super smooth, clean coffee. It’s also super easy to clean, coming apart easily so you can access all the parts that might otherwise be hard to reach. And it’s as portable as the Aeropress,fitting easily into your travel bag, or even your pocket. If you’re looking for a different approach to travel brewing and favour a cleaner cup, the Delter could be your guy.
