This new porcelain dripper from Bonavita produces the bold, full-bodied coffee you'd get from a French Press with the convenience and control of pour-over coffee. It's a great way to upgrade your coffee brewing
The Bonavita Porcelain Immersion Dripper works like the popular and appropriately named Clever Coffee Dripper. Both have an open/close valve at the bottom of the cone that lets you steep coffee grounds for a few minutes (in a #4 paper filter) before releasing the brew into your mug. Thus, you get the best of all worlds with this hybrid press-pot-meets-pour-over, with none of their downsides. The result is smooth, sediment-free, and complex coffee with really easy cleanup.
Bonavita's porcelain version has a few advantages over the plastic Clever. You don't have to worry about the possible health risks from hot water mixing with plastic, and the porcelain retains heat better. It's also really sturdy and dishwasher safe.
One downside is the bottom of the porcelain cone has little parts that can be tricky to clean, but, again, you can run it in the dishwasher. Also, because it's opaque, when you first get used to brewing with it, it helps to use a clear or translucent mug or one of those fancy brewing stands.
You can get a couple of cups out of this at a time (or one large mug), thanks to the 16-ounce brewing capacity.
The Bonavita Porcelain Immersion Dripper also costs $40 versus the Clever's $22, but I think the porcelain dripper is well worth that small investment (as does Serious Eats).
