Derek Calloway

Derek Calloway has been pulling espresso shots at home and in semi-professional settings for over eleven years, starting after a trip to Bologna where a single ristretto at a train station bar changed his expectations permanently. He focuses primarily on prosumer lever and pump machines in the $400 - $2,000 range, with particular attention to boiler stability, group head temperature consistency, and long-term build quality. He has personally owned or extensively tested more than thirty machines, from entry-level Gaggias to La Marzocco Linneas, and keeps detailed shot logs to back up every rating he publishes. His writing exists because most espresso reviews online conflate price with quality and skip the variables that actually matter to someone pulling ten shots a week at home.
