If it flows very slowly to the point of dripping, the pod is packed too tight or the coffee is too fine. If you have packed it really tight it may stop the flow altogether. We recommend grinding your beans on to a fine-to-medium grind if you're using a grinder. If you're using the correct grind and the water still slowly drips out, pack your Pod Star capsule a little lighter. Don't forget we sell Lygon Street Coffee which we have ground to the perfect capsule grind for you.
