amzchef CM1666 20 Bar Espresso Machine: features, specs and who it suits

The amzchef CM1666 is a compact semi-automatic espresso machine in stainless steel, with a milk frother and an LCD control panel. It is designed for home kitchens where space is limited and for people who want to make espresso, cappuccino and latte drinks themselves. It measures about 12.5 x 6.5 x 12.0 inches (32 x 16.5 x 30.5 cm).

What "20 bar" means

The 20 bar figure is the pump's maximum pressure figure. Espresso is traditionally brewed at around 9 bar at the coffee puck, so the higher number is the pump's capability, not the pressure at the grounds. In practice, grind size, dose and tamping have more influence on how a shot turns out. Treat the figure as a sign of a pump with spare capacity.

LCD panel and brew options

The machine has an LCD panel that shows its working status. Buttons let you switch between single-cup, double-cup and manual brewing. Manual brewing is typically the option for people who want to stop the shot themselves, while the preset modes give repeatable volumes.

Adjustable temperature

amzchef says you can set the brewing temperature to your taste, whether you prefer coffee hotter or a bit cooler. Temperature affects flavour: hotter water tends to extract more bitterness, and cooler water can taste sharper or more sour.

Alerts for water and overheating

The machine gives reminders for low water and overheating, with sound alerts and messages on the screen. amzchef says that after refilling following a low-water alert, you should turn the milk frother's knob to release pressure, which it says helps operation and the machine's lifespan. Read the manual for the exact steps.

Milk frothing

The frother is described as a powerful steam system that produces creamy microfoam for cappuccinos and lattes. Steam wands typically need practice: keep the tip just below the surface to add air, then lower it to heat and swirl the milk. Always wipe and purge the wand after each use.

Filters, tank and cleaning

The package includes the machine, a detachable water tank, a single-cup filter, a double-cup filter, a pod filter, a spoon and a user manual. The pod filter means the machine can be used with pods as well as ground coffee. The detachable water tank and drip tray make cleaning easier, and a removable tank is simple to refill at the sink.

Who it suits

It suits people moving up from a capsule or drip machine who want to learn espresso, small kitchens and offices, and gift buyers looking for a starter machine. Because it is semi-automatic, you control the grinding, dosing and milk steaming. A separate grinder is not included.

What to check before you buy

• Counter space: check the height with the lid up and the clearance under shelves.
• Coffee supply: decide between ground coffee and pods, and think about a grinder.
• Cup height: make sure your cups and jugs fit under the group head and wand.
• Milk jug: a small jug helps with frothing; one is not listed in the box.
• Upkeep: check the manual on descaling, cleaning and water quality.
• Hot parts: steam and hot water are involved, so follow the manual's safety guidance.
