you gotta have the equipments and the right ingredients. There’s a lot of types of coffee, what exactly do you want to make? If it’s just regular coffee and you have a coffee maker just buy ground coffee beans at your favorite coffee shop or wherever you’ll find good coffee. If you’re not satisfied with the coffee maker coffee, i suggest you buy a French Press. It makes coffee that’s more flavorful and it’s very easy to use, doesn’t need coffee filter or electricity.
If you’re more interested in making flavored coffee like in starbucks, you’re gonna need an espresso machine and learn how to steam milk properly.
