I brew with a French Press, using a Mr. Coffee burr mill to grind my own beans. I'd love to hear people's thoughts on what kinds of different flavor results can be expected when you a) brew for a longer time, versus when you b) add more coffee to the pot. My normal routine is about 1/3 cup (?) of grounds (#8 on the grinder), semi-coarse grind (halfway between medium and coarse), and brewed for about 3.5 minutes with 48 oz. of 200-ish water. I'm willing to do some experimenting, but I wanted to see what info was already out there before doing so. Thanks!

A) More compounds extracted, bitter harshness prevail

B) More coffee, same water will produce a thicker brew with more compounds present, harsh, thick, over abundant flavors

If the grind is the only thing changed then a smaller grind will extract more then a more coarse grind due to more surface area.  Grind too fine the coffee will over extract (strong), too coarse and it will under extract (weak).

Thanks, Tim. So if I want a "stronger" coffee, with less chance of bitterness, it seems like adding more coffee to the water is my best bet - or possibly reducing the size of the grind. And a longer brew tends to be a more bitter brew. I'll give it a try!

If your coffee is bitter your brew water may be too hot, but yes adding more coffee alone will make the flavor "stronger" to taste.

How much coffee and water are you using?  Are you using a scale to weigh them both?

My coffee isn't bitter at all, but it's also not as strong/flavorful as I'd like. It's a medium dark roast, so I expect a bit more of a kick than I'm getting.

The temperature is the one thing I'm pretty careful about measuring. I always make sure it's between 200 and 205. But I haven't really measured the amount of coffee I use; as I said, it's around 1/3 of a cup in my 48 oz French Press. And I pour the hot water until it's just full enough to not overflow. I set my timer for 3 minutes, but usually don't push the plunger down for another 15 or so seconds after that.

What beans are you using and how fresh?

It's a blend of medium and French roasts from Cafe Mam called Viennese Blend, and they're very fresh at the moment. I do freeze a 5-lb bag, so it takes us a while to go through it, but the flavor doesn't really vary too much from first opening to bottom of the bag.

Any chance you can weigh that "1/3 cup" so we can gage your brew ratio.

Try steeping longer too. Overextraction is very unlikely, however fine you go, in 3.5minutes, you may have trouble keeping bittering, fine particles out of the cup though, with a very fine grind. After your 3.5 minutes, remove the plunger & pour the first 1/4 cup of liquid away (mostly oil), then taste a little...if it's good decant & enjoy, if not, put the plunger back & come back in 5 mins, repeat until you get nice coffee. There are probably a couple of high preference extraction points, so you usually get "2 bites of the cherry" so to speak.

I'm actually leaving today and won't be back until the weekend, but I'll weigh it then. I'm very interested to hear what you say about the amount; I had no idea coffee could be portioned by weight, but it makes sense.

And an 8-minute steep, huh? That's very intriguing. I'll give it a try!

I rarely disturb a steeping pot before 10-15 minutes, might not actually drink it for 2-3 times that.
