Your coffee is leaking around the rubber seal. With use the seal eventually will become loose and let some coffee leak around it. You wrote that you store the plunger inside the main part. The AeroPress instructions advise against storing the seal inside the chamber because holding the seal compressed inside the chamber eventually will reduce the size of the seal, enabling coffee to leak around it. When your seal becomes loose, you can buy a new seal on this website. The seal can easily be replaced on the end of the plunger.
- previous post: Ive been using an aeropress for 5 years now. Love the coffee flavour and convenience. My only suggestion is that you make one that makes twice the volume so i can do my wife and my coffee at the same time. Basically i reckon the go travel version with its own stackable 2 cup jug would be a hit. If you think this idea has legs please just send me 6 of the completed product that I can share around friends and family. – From Kent H.
