AMZCHEF CM1666 20 Bar Espresso Machine: features and who it suits

The AMZCHEF CM1666 is a compact semi-automatic espresso machine with a built-in milk frother. It lets you make espresso, cappuccinos and lattes at home without a large counter footprint. An LCD panel shows what the machine is doing, and the temperature can be adjusted.

What "20 bar" and "semi-automatic" mean

Bar is a unit of pressure. Espresso is traditionally brewed at around 9 bar at the coffee, and the 20 bar figure on home machines usually describes the pump's maximum pressure rather than the pressure at the puck. A higher number is mostly a marketing spec, so look at other features too.

"Semi-automatic" means you grind, dose and tamp the coffee yourself, and the machine controls the water flow once you start the shot. That gives more control than a pod machine, but there is a learning curve.

The LCD panel and brew options

AMZCHEF says the LCD control panel shows the machine's working status. With a button press you can switch between single cup, double cup and manual brewing. Manual mode generally lets you decide when to stop the shot, which helps if you want to adjust the strength or volume.

Adjustable temperature

The listing says you can adjust the temperature to your taste. Water temperature affects extraction: hotter water tends to pull more bitterness and body, cooler water can taste sharper. Having a control lets you experiment with different beans and roast levels.

Alerts

The machine gives low water and overheating alerts, sounded and shown on the screen. AMZCHEF says that after a low water alert, you should rotate the milk frother's button to release pressure when refilling. Read the manual before first use for the exact procedure.

Milk frother

The frother uses steam to create microfoam for cappuccinos and lattes. Steam wands take practice: the aim is to introduce a little air to stretch the milk, then swirl it to a smooth texture. Wipe the wand after each use to avoid milk residue.

Size, tank and cleaning

The dimensions are listed as 12.0 x 6.5 x 13.0 inches (about 30 x 16.5 x 33 cm), making it narrow enough for small kitchens. The water tank and drip tray are detachable, which AMZCHEF says makes cleaning easier. Regular descaling is typically needed on any espresso machine; follow the manual for how often and with what.

Who it suits

It suits people who want to learn espresso at home, households that drink milk-based coffees, and small kitchens that can't take a larger machine. It also suits anyone who prefers to choose their own beans rather than using pods.

What to check before you buy

• Grinder: the listing doesn't mention one, so plan on freshly ground coffee or a separate grinder.
• Space: check the height clearance under your cabinets, especially for the water tank.
• Cup size: make sure the cups you use fit under the group head and drip tray.
• Upkeep: plan for descaling and cleaning the frother.
• Hot surfaces and steam: follow the manual's safety guidance, and keep hands clear of the steam wand.
