Technically, neither. I do not care for instant coffee much at all, but my personal preference for at home is "cowboy" coffee. I started doing it this way because I don't have a coffee maker anymore. I don't have the space for it and gave it away when I was not drinking coffee some time ago. Since I have literally no place to put one, I did not get another one when I started drinking coffee again.
I like to get organic whole beans, grind them right before making the coffee, which is super easy. Just put grounds in water, bring to a boil and pull off the stove once it boils. Then I go take a quick shower, come back and pour it through a large tea strainer into my teapot. I like making it this way because I get more flavor from the beans than I would if I used a filter, so I can have more onces of coffee without going overboard on the caffeine.
