The grounds are good fertilizer if that makes a difference in terms of disposal.
Even if you don't buy coffee frequently, grinding right before using (no more than 10 minutes) really does make a difference.
A couple quick points in addition to that above:
1. Water temperature. 180-200 seems to get a better extraction than 212 so I let the water sit for a bit after boiling. As with tea, I tend to think some coffee works better on the 200 side and some better at the 180 side. Try both with a batch of beans and decide for your tastes.
2. I also think that warming the carafe makes a difference. After the water boils I pour a few ounzes in the carafe, put in the plunger, and swirl. Once the water still in the kettle has cooled, I dump the water from the carafe and begin the actual brewing process. I do this with cups when making espresso and with my teapot too, so it may just be habitual.
3. "Pre Soak." That may be a deceptive term. After the carafe is warmed and the water has cooled a bit, I dump in the grounds, measure out my water into a pyrex container, pour about four ounces over the grounds, and swirl or stir them. If you put your ear over the carafe, you will hear the grounds fizz a bit ... or blossoming/blooming as I prefer to think of it. When the grounds have fully bloomed, add the rest of the water. I put the top on to keep in heat and have it ready to plunge.
4. Use enough grounds. 2 heaping tablespoons for 6 oz of water is a decent baseline. I think most coffee scoops are approximately 2 tablespoons so one heaping coffe scoop is the equivalent.
5. Don't brew too long. 3 - 5 minutes. 3 doesn't seem very long but it might be the case that after 3 you're only extracting nasty flavors, bitterness and astringency.
6. Plunge carefully. Hold the top and push the plunger down slowly and evenly. If the plunger goes down unevenly grounds can come around the upturned side. This doesn't really ruin the flavor, but it puts grit in the cup.
7. Don't let the remaining coffee sit on the grounds. If you pour two cups and you have more in the pot, pour it into another container or it will continue to extract and nastify.
None of these really add burden, their just refinements of process. Maybe I'm missing something but, why can't this coffee compare to that found in Europe? Are you talking about straight brewed coffee or something else? The quality of the milk, the espresso, etc?
