Wrecker – that’s one complicated method for what is an easy operation!
What gind coffee are you using – cafetiere/filter or espresso? In an emergency I used rough cafetiere style grind and it dripped through like you say but with a finer grind – not a drop ever.
coffee in, water in, wait a few seconds, stir a little with the other end of the scoop, wait a few (about 3!)more seconds, plunge, top up with water, drink. One level scoop for a normal mug, two for a stupid sized pint mug. Using 2 scoops of fine grind I recon I have to apply 10-15kg of pressure to get the coffee to start to come through – about 2/3rds of that for a single scoop.
