lefty, planning on some coffee masochism with that pourover?
The little valve nipple thing just broke off on my CCD rendering it effectively a pourover cone, and while waiting for its replacement, I've been using the Aeropress for the last couple of days. The most interesting difference between the CCD and the Aeropress (both nominally full-immersion brewers) is that the Aeropress brews significantly lighter coffee. I don't think it's underextracted, but the resulting brew is lighter in color, more transparent to light, and really emphasizes the fruit notes in the coffee. It's like what the CCD is to press pot, the Aeropress is to the CCD. There is definitely much less traditional coffee flavor.
I've tried the same brew parameters, and the Aeropress is still lighter. For example, I still use a 6% ratio (12g grounds to 196g water in the AP, and 22/360 in the CCD), same grind size, same immersion time (3 minutes), same water temps, and paper filters. The Aeropress had to be used upside down to do this. The only difference is that the press time of the AP is much faster than the drain time of the CCD, at around 15 seconds compared to 1 minute. Maybe I'll try a 4-minute immersion time, but I'm not sure that will change things that much.
edit: another thought just occurred to me: I could remove the Aeropress plunger, and just let it drain instead of pressing the coffee through.
