FAQs
A dual boiler espresso machine has two separate boilers: one heats water for brewing espresso, and the other supplies steam for milk steaming. Each boiler operates at a temperature suited to its task. Many models let you brew espresso and steam milk at the same time.
A PID is an electronic controller that regulates boiler temperature. On many home dual boiler espresso machines, you can adjust the brew temperature through a display or menu. Depending on the machine, the steam boiler may have its own adjustable temperature setting.
Choose an espresso-capable burr grinder with fine grind adjustments so you can dial in your shots. Round out your setup with a scale for measuring coffee doses and espresso yield, a tamper matched to your basket, and a milk pitcher for steaming. A knock box and dedicated cleaning cloths keep your coffee station organized.
Let the machine reach operating temperature and allow the group head and portafilter to warm up according to the manual. Weigh and grind your coffee, distribute it evenly in the basket, tamp, and start brewing. Steam milk as needed, then empty the basket, wipe and purge the steam wand, and rinse the portafilter.
After each session, rinse the basket and portafilter, wipe the steam wand, and empty the drip tray as needed. Follow your machine's instructions for backflushing and cleaning products. Use water that meets the manufacturer's specifications, replace filters on the recommended schedule, and descale only as directed by the manufacturer.
