Which kind of coffee do you like?

First coffee that i usually drink are instant coffee. Instant vending machines are widespread throughout the country.
These days, my favorite coffee is americano. Americano tasted little bit bitter, but americano had a taste that make you to drink more often. First i started to add a little bit of syrup or sugar to drink, but today i drink it without syrup.
