The Grower's Cup coffee brewer is best described as a single-brew French press. Inside the pouch is a filter with 18g of freshly ground specialty coffee. To brew 2 cups of delicious coffee, all you need to do is: open, pour 300ml (10 oz) hot water into the pouch, and let it brew 2-4 minutes. The filter is designed to preserve all the natural oils and flavors in the coffee and provide the same rich taste as coffee brewed in a French press. Integrated, re-sealable pour spout. Freshly brewed anywhere, anytime.
