The world's first disposable coffee maker is said to be a hybrid between a filter dripmaker and a French Press, except this Grower's Cup option is portable. It's perfect for camping trips or other events that require a tasty cuppa joe.
Grower Cup's pouches are a waterproof polyethylene-coated paper bag that comes with 25 grams of ground coffee inside it--available in different flavors. To brew a cup of coffee you only have to open the bag from the top, pour in half a liter of boiling water, before pouring out your brewed coffee through a spout on the side.
There is a filter where the coffee is positioned, so the brew doesn't touch the grounds while it's 'percolating'. This way, your coffee won't become bitter. The specially designed filter works like a French Press to preserve the coffee's oils, flavor and aroma.
