COWSAR CM8054 20 Bar Espresso Machine: features, specs and who it suits

The COWSAR CM8054 is a compact, semi-automatic espresso machine with a steam wand for milk. It is aimed at people who want to make espresso, cappuccino and latte at home with some hands-on control. Semi-automatic means you handle the grinding, dosing and tamping yourself, and the machine controls the pump and water.

What 20 bar means

COWSAR specifies the pump at 20 bar. Espresso extraction typically needs around 9 bar at the coffee, so the pump figure is a maximum capacity rather than the pressure on the coffee itself. COWSAR says the high-pressure burst helps pull more coffee oils and gives a thicker crema layer. In practice, results still depend on the grind, dose, tamp and the beans.

Pre-soak for even extraction

Before full pressure is applied, the machine pre-soaks the coffee. COWSAR explains that lower pressure at the start lets water moisten the grounds evenly and gently. This reduces air bubbles and the chance of channelling, where water cuts a path through the puck and skips the rest of the coffee. Pre-infusion of this kind is common on espresso machines, and it tends to make shots more consistent.

LED display and controls

The machine has an LED display with knob and button controls. COWSAR says it shows brewing data at a glance and allows finer control over the shot. A clear display is helpful while you learn to dial in a new coffee.

Steam wand for milk

The steam wand is there for lattes, mocha and cappuccino. COWSAR says it blends steam with the milk to make denser froth, from creamy to foamy, and that this improves the chances of latte art. Steam wands take practice: keep the tip just under the surface at first to add air, then submerge it to heat and texture the milk.

Water tank and size

The 45 oz (about 1.3 litre) tank is removable, so you can fill and wash it at the sink without lifting the machine. The unit measures 14.2 x 8.9 x 13.6 inches and weighs 7.9 lb (about 3.6 kg), a footprint that fits on most countertops.

Who it suits

It suits home users who want to learn espresso basics and make milk drinks without a large machine. Because it is semi-automatic, it rewards some patience and practice.

What to check before you buy

• Grinder: the listing doesn't mention a built-in grinder, so you will likely need a separate one for fresh beans.
• Accessories: check the manual or box contents for the portafilter, baskets, tamper and any other parts.
• Counter space: allow for the 13.6 inch height when opening the lid and filling the tank.
• Cleaning and descaling: look up the schedule for the steam wand, drip tray and descaling.
• Power and warm-up: check the electrical requirements and how long the machine needs to heat before the first shot.
