Some years back, I bought my first home espresso machine, a basic model from Italy’s Gaggia. It was a faithful kitchen companion for several years until it gave-up the ghost, but I digress.
To make espresso, you need a decent grinder, and that means getting a burr grinder. At the time, I made an “adequate” choice, namely a KitchenAid model—a choice made as much for décor reasons as functional ones. In its defense, it lasted longer the Gaggia, but it too recently needed replacement as plastic parts began to break, and were not replaceable. It was also clear that the burrs needed to be replaced, but were no longer made for the specific grinder model I owned.
