We found the flat-bottom, three-hole design of the Kalita Wave 185 Pour-Over Coffee Dripper allowed for the most even and consistent brewing of all models tested. Yes, you will need to buy special wavy Kalita filters to fit inside the dripper (which we admit is a pain), but the Kalita produced the most robust coffee, maintained spot-on heat temperature, and the most even saturation of the grounds (which extracts more flavor). There is also a lot to love about the OXO Brew Pour-Over Coffee Maker with Water Tank. Perfect for beginners, it takes the guesswork out of the pouring process by allowing you to simply fill the water tank to your desired amount and letting it control the flow rate. No, the coffee flavor wasnât as rich and full-bodied as that produced by the Kalita, but the OXO kept its heat, was super simple to operate and extremely convenient.
