It’s unclear if you know this (you probably do) but espresso beans aren’t really necessary to make good espresso. Espresso beans and coffee beans are the same thing, just roasted differently maybe. I know too many people that buy an espresso roast and use it in their drip coffee maker and they think they are making espresso. It’s probably actually worse because a ground espresso roast is ground finely as it is make to be used in an actual espresso machine.
