Is it possible to make espresso without any kind of special machinery?
If it’s instant espresso powder, then it’s just that, instant, mix it with water or milk. If you want espresso, as from finely ground espresso beans, then yes, you do need special machinery. True espresso needs to be high pressure extracted by forcing hot water through the grinds in a filter at high pressure. If you use good quality beans that are properly ground and fresh, then you dont need a particularly expensive machine in which to brew coffee, no.
