What Machines Are Really Used in Coffee Shops?

Ever walked into a coffee shop and been immediately struck by the massive machine behind the counter? It looks expensive, professional, and way out of reach for home use. But what exactly is that machine — and what else is behind the scenes making your espresso possible?

The short answer: every serious coffee shop runs on at least three key machines — a grinder, an espresso machine (usually Italian-style), and a steam wand system — often backed up by multiple units to handle rush hour. A high-volume shop might have several grinders and a triple-group espresso machine to serve six drinks at once.

Why Every Coffee Shop Needs a Grinder

Coffee shops rely on a dedicated grinder to freshly grind coffee beans right before brewing. Freshness is key — pre-ground coffee loses aroma and flavour quickly. Most shops set their grinders to standardised settings for consistency, but pros know better: different brew methods need different grind sizes. That’s why top-tier cafes often use multiple grinders — one for espresso, another for filter, and sometimes more for specific drinks.

The Heart of the Shop: The Italian-Style Espresso Machine

The espresso machine is the true centrepiece of any coffee shop. These machines use steam pressure to force hot water through finely ground coffee, producing espresso. The most common setups are one-group, two-group, or three-group machines — each 'group' corresponds to one group head with its own pump. A one-group machine handles one shot (or two cups) at a time; a three-group machine, with three pumps, can brew up to six shots simultaneously. This is why busy shops never seem to run out during the morning rush. These machines are plumbed directly into the water supply for uninterrupted use.

Steam Wands and Hot Water Taps

Flanking the espresso machine, you’ll usually find two metal tubes — the steam wands. These produce high-pressure steam used to heat and texture milk for drinks like lattes and cappuccinos. They also provide hot water for Americanos or tea. The steam wand is essential for creating microfoam, the velvety milk texture that defines many espresso-based drinks.

Cup Warming on the Machine

Most espresso machines have a flat top where cups are stored. The heat from the machine keeps cups warm, which helps maintain the temperature of the final drink. It’s a small detail, but one that contributes to better customer experience and better thermal stability for espresso pours.

Frequently Asked Questions

How many grinders does a coffee shop really need?

A basic shop might get by with one grinder, but serious shops use multiple — often one per brew method. For example, one grinder dedicated to espresso (fine grind), another for filter coffee (coarser), and sometimes more for specific blends or single origins. This ensures each coffee is ground to the optimal size for its brew style.

What’s the difference between a one-group and a three-group espresso machine?

A one-group machine has one group head and one pump, making one or two espressos at a time. A three-group machine has three group heads and three pumps, allowing it to brew up to six espressos simultaneously. The more groups, the more drinks the machine can produce at once — critical for handling busy periods.

Do all espresso machines need to be plumbed in?

Not all, but most commercial machines are. A plumbed-in espresso machine connects directly to the water supply, ensuring a constant flow and reducing the need for manual refilling. Some smaller or portable machines use water tanks instead, but they’re less common in high-volume shops.

What do steam wands actually do?

Steam wands heat and froth milk by blowing high-pressure steam into it. This process heats the milk and creates microfoam — the velvety, fine bubbles essential for drinks like cappuccinos and lattes. Steam wands also dispense hot water for other beverages.

Why do coffee shops store cups on top of the espresso machine?

Cups are stored on the top of the machine to keep them warm. The residual heat from the machine helps maintain the temperature of the espresso when poured into the cup, improving both taste and customer comfort. It’s a simple but effective practice.
