I am a coffee expert. First, flavored coffee is not the same as raw straight coffee. I get my coffee straight from Cook Island, Hawaii by a seventy year old man who picks, husk, and cooks only 200 lbs a year. I am 1 of his customers and I buy 5 lbs at a time. Ground coffee looses 1/2 its flavor to evaporation, grinding your own at time of brew releases all the flavor and oils which produce the true flavors. Never use a percolator as it cooks the coffee twice and makes it bitter. Use a drip, French press or gravity feed coffee maker. Steam can also be used to extract. Some of the best coffee comes for Hawaii, Jamaican blue, Indonesia, Sumatra and Columbia. I have had them all including Kopi Luwak which is shit from a tree cat and cost 125 a lb. Didn't like it. Ethiopian coffee is good but strong. Most commercial coffee is a blend of beans not a straight bean. If you buy a commercial blend be advised that A&P 8 o'clock was rated #3 of the coffee blends with Dunkin donuts being #1 in commercial blends. Yes fancy or prime coffee cost much more and the reason is the flavor. My coffee in bulk cost 22.00 a lb but if you love your coffee, its worth every penny.

Green Mountain used to be small time coffee company until they bought the patent for the K-CUP and then purchased the whole Keurig company outright.
The company had insight and smarts both in advancing the company but also in setting trends and convincing the public of a convenient way to brew coffee. It's not cost effective though and some machines do not brew at the correct temperatures. The old French Press system works fine in a pinch.

If you like flavored coffees, then try KONA and add your flavor to taste.
