I have to use all my strength plus upper body weight to depress the plunger. Sometimes brew shoots out the sides of the top of cup in the process. I follow all Aeropress instructions, use both inverted and upright press positions, and Starbucks ground coffee. I store the maker with plunger inside tube and use Aeropress filters. I have read several letters from others who were unable to resolve the issue. What do you recommend? P.S. The coffee once made is very good, though. I don't want to give up on it. Thanks. – From Christine D.

We recommend pressing gently and having patience when brewing with an AeroPress. Try it. You will be surprised. That's because pressing hard compacts the bed of coffee and blocks the flow.
