I got a pourover coffee funnel for xmas. We otherwise use a french press. I mentioned this fact to my coffee nerd friends and one suggested a visit to Brew Methods. Brew Methods aggregates detailed instructions for a variety of coffee brewing methods and apparatuses. Many include video instructions.
One thing I’ve noticed is that every set of instructions says to preheat all the vessels. I never do this, and that seems to be fine for our stainless steel insulated french press pot, but I’ve found that it does make a difference for a single glass or ceramic mug when I do pourover.
