This is a double shot?
I don’t claim to be an expert on this subject but I do have an opinion on what is good espresso. First of all espresso is a coffee brewing method not some special type of coffee bean, a blend, or some special roasting method. All coffee drinks, regardless if it is espresso coffee, drip coffee, pour over coffee, etc., are brewed by using water filtered through coffee grounds to extract the soluble flavors from the coffee into the cup.
