Delter Coffee Press has been designed to solve one of the biggest problems in coffee brewing - agitation. To avoid a bitter and inconsistent extraction caused by uncontrolled agitation, the Delter Coffee Press uses a unique jet-seal. This seal keeps the brew water and the coffee grounds separated until the brew commences, preventing uncontrolled agitation. When pressure is applied to the plunger, water and coffee contact is activated, allowing agitation to occur for the first time. This design allows the user to have complete control over the water flow and agitation, resulting in a brew with less bitterness and more clarity.
- Jet Seal: Unique seal that prevents any unwanted agitation of the coffee bed during brewing.
- Injection Brewing: The water and coffee are separate until you're ready to start brewing using injection brewing.
- Simple to Clean: All you need is a few minutes to wash with water
- Portable: Weighing less than 250g, the Delter is ideal for camping, plane, travel, office or home.
- Pocketable Design: Compact and portable for coffee anywhere

2. Add freshly ground coffee into the Delter coffee chamber (max. capacity 30g).
3. Twist on the Delter cap.
4. Flip the Delter over onto your cup and start pouring your hot water into the brew chamber, filling to the line markings.

Q: The seal doesn't seem to be sealing properly. What can I do?
A: Usually, when coffee is sucked back upwards into waterchamber, it's a sign that there is built up 'back pressure'. When you take yourhand off (or raise plunger) the excess pressure escapes back up through theseal. This usually has three causes: 1. Too much downward force being applied;2. Your coffee grinds are too fine; 3. Your coffee dose is too high. To resolvethis issue, try to press more slowly, try grinding your coffee a little coarser,or lower your dose.
Q: The water doesn't seem to be passing through the seal. How can I fix this?
A: This could be linked to pressing too hard on the plunger.Instead of the cap, it?s the seal that has been designed to relieve any excesspressure. The idea with Delter is to press softly to extend the dwell timebetween water and coffee, and reduce the agitation of grounds in theprocess.
