I just got a percolator, the kind of coffee maker where you put it on the stove like a kettle and the water goes up through the metal basket when it boils. I know you have to boil it for a few minutes but I forget exactly. I only drink one cup of coffee in the morning but it has to be strong enough to win in a fistfight.

I just purchased my first drip coffee maker. A 5 cup black and decker. I bought a pack of Columbian coffee. I noticed that when I try to make coffee, my coffee isn’t like black…it’s like a dark brown. I add 2 1/2 scoops for one cup of coffee. Also it still has a watery taste. Like the coffee isn’t strong enough I guess. Also my coffee isn’t HOT…it’s drinkable right away. So basically if I left the coffee sitting there for 10 minutes it would be just lukewarm. Is that normal? Is the coffee supposed to be scalding hot when it comes out? And why isn’t it black!! It also has a bitter/burnt taste…not smooth like say even Mcdonalds coffee…and that’s not saying much…help!

When you buy a cup of coffee at a store or at a gas station, what do they put in the coffee besides coffee beans and water? For example, I have heard that they put preservatives in coffee sometimes. Can coffee contain any vegetable oil products (such as mono-and-diglycerides?) When I eat things with vegetable oil I am convinced I have an adverse reaction, which I think I can get to a slighter degree from drinking coffee, which is why I asked. I am convinved vegetable oil is very unhealthy.
It disgusts me that I have to ask this question.

What does roasting do for the coffee?

I am thinking about juicing beans, to create a very strong cup of coffee, that does not have any burnt taste.

For this I believe that I should use un-roasted green coffee beans.

I have a lot of ignorance in this area though and need help and suggestions.
