I'm not sure if this is the correct forum for this, but I found another post regarding the Aeropress on this one, so here goes...
I just got my Aeropress and a French Press, but I am a complete coffee newbie. I have a burr grinder, which seems to work fine, but my problem is that every cup of coffee I attempt to make (with either AP of FP) seems to come out bitter.
I have tried different grinds, different temperatures, different amounts of coffee/water/time...but I can't seem to get that killer combo. What am I doing wrong?
Could the beans be the problem? At the moment, the only beans I can get hold of are ones that may have been sitting at the store for a while. I'm in the UK, and it's hard to get fresh beans. I'm about to order some from a web site which will roast and post, but if that's not the problem, I don't want to get the beans until I solve it.
The beans are likely responsible for at least part of your problem. Are they very dark, lots of oil on the surface of the beans? Do they smell burnt? Can you write with them? (sorry for that last one, couldn't help myself )
What make/model of burr grinder do you own? How fine are you grinding for your french press, how much coffee to water are you using, and how long do you steep the coffee before pressing?
Some are burnt Starbucks. Others come from a UK tea/coffee speciality chain store, but they certainly weren't roasting them on-site, so they may well be old. They are named origin, though (Monsoon Malabar, Kenyan Peaberry, etc.). I'll check for oiliness when I get home.
I started with the middle setting and have gone about halfway in either direction (fine/coarse).
FP: 1.5 to 2 7g scoops for a 12oz mug.
AP: 1 to 2 of the supplied scoops, water to 1 or 2 on the AP markings. Dilute remainder to fill 12oz mug.
