Some are brewed with instant coffee, because not every type of fancy coffee can see coffee oil, and not everyone who drinks it understands it. In fact, you can see whether it is brewed or not. Cafes usually have a bar. All fancy coffees are made fresh, and you can see the brewing process. Coffee brewed from beans is completely different from instant coffee. Instant coffee basically does not have the aroma of coffee beans. Anyone who has drank freshly ground coffee knows this aroma, which instant coffee does not have. So just watch it when you drink next time. If it is a larger coffee shop and brews in a special studio, you can ask for a coffee bean to be provided when you serve the coffee (the type of coffee you ordered) ), you will know when you compare them.

I own a coffee shop, and I also know that some cafes use instant coffee, and some coffee beans are left for a long time. Even if there are beans, there is no steam coffee machine, but siphon coffee. Pots, Moka pots, etc., the coffee produced is naturally not very suitable for making fancy coffee. Usually when I go out to drink coffee from other places, I will ask to see the process or give me a bean, and usually people will be willing to do so.

Hope this helps.
