Pouring a small bit of water over your coffee grounds and letting it sit for a short time before continuing is called blooming. This step is fast and easy, and can make your coffee even more delicious. If you’re camping, the best way to perform this step is with a pour over kettle or a French press. The best way to bloom coffee is to even dampen your grounds and allow them to bloom. You’ll see this bloom as your grounds bubble and rise. Let them do this for about 30 seconds, which will release carbon dioxide. Then you can pour the rest of the water. Carbon dioxide makes coffee taste sour, so releasing it before you pour out the rest of the water will eliminate the barrier between the water and the grounds, producing more flavor.
