I'm no longer addicted to caffeine and don't really need it, but I bought a bag of beans yesterday and I think I may have found my proper way to pour a cup of coffee using a filter cone.
I've been experimenting for years trying to come up with a consistently good (to me, that's why I say my proper way) cup of coffee. I've even searched on the web to see how other people do it and either it's super-anal techniques that no normal person in their right mind would pay attention to, or nimrods who post the most obvious, derp-city way to use a filter cone that even a monkey could figure out.
Experiment factors include grind (how long to grind), water temp (how long to let it cool), and how to pour. There's a lot to personal taste, so how long to grind and water temp is an individual preference. I grind for 10-15 seconds, and let water cool for a minute.
The pour, I think, is the key and that's with what I've been experimenting. My way is don't saturate the grind right away. I do a quick, short line pour that just introduces the water to part of the grind and for what that's worth, let it soak in for a few seconds; it's not enough to even start a drip. Then a second line pour with the same intent, not necessarily enough to drip, but just soak whatever grind it hits.
Then after another few seconds of letting that soak and settle, do a circular pulse pour that will likely cover the rest of the grind and instigate the drip if it hasn't already. From then, I add water gradually by pouring along the rims of the grind, never right onto the center of the grind, and each time letting the coffee drip out some (never completely) before adding more water. As the grind is saturated, it will take longer for coffee to drip out and so the water level will rise in the cone, but what I find works is keep the water level down as much as possible at first.
And it should foam naturally this way. I vaguely recall from way back someone recommending something about how much the grinds should foam. That kinda makes sense to me, not knowing the science, because it seems it might have something to do with aerating the grind which might have some beneficial effect on the "extraction".
I note that my way goes against other people's advice that the grind should be saturated immediately. I've tried that and I like the taste of my way better. If I were to get zen philosophical parody about it, my initial, non-saturating line pours are like getting the grind's attention and telling it "you are about to become coffee, breathe and smile", as opposed to just drowning the grind in complete saturation.
Also with my way, at the end of the drip, the grinds shouldn't be deposited high and thin on the filter, as with many coffee makers, but concentrated relatively low, which might make sense for good extraction, but again I don't know the science.
I think the key is hearing how other people do it, try it, experiment with variables and then if you're consistently quoting Harrison Ford saying, "Now that's good coffee!" (Witness), bam.
