A capsule coffee machine offers a quick and effortless way to prepare single servings of coffee. It operates using pre-portioned coffee capsules that are inserted into the device. Hot water is then forced through the capsule at high pressure, producing a finished coffee beverage in a very short time. The key advantages of this system are its consistent flavour quality, simple operation, and minimal cleaning effort. Their compact design also makes them a space-saving solution for kitchens and offices.
When selecting a suitable capsule coffee machine, several technical parameters should be considered. These include the capsule system used, the maximum pump pressure, the availability of milk frothing functions, and the dimensions and capacity of the water tank.
The decision to purchase a single-serve coffee machine should be based on an analysis of your individual needs and the technical specifications of the available models.
The capsule machine market is primarily differentiated by its various capsule systems. Closed systems, such as those offered by Nespresso with its Original and Vertuo lines, are only compatible with capsules from the manufacturer or licensed third-party providers. Open or multi-format systems offer greater flexibility, as they can process capsules from different brands and in various formats. Some models also allow the use of refillable capsules or adapters for ground coffee, which can reduce both running costs and waste.
The pump pressure, measured in bars, is an indicator of the machine's ability to force water through the coffee grounds in the capsule. To prepare an authentic espresso with a stable crema, a pressure of at least 9 bars is required. Most capsule machines on the market operate with a pressure between 15 and 20 bars. A higher pressure can lead to a more intense flavour extraction and a richer crema.
For preparing coffee specialities like cappuccino or latte macchiato, a capsule machine with a milk frother is necessary. There are two basic types:
The size of the water tank determines how many cups of coffee can be prepared before it needs refilling. Smaller models with a tank capacity of less than 0.7 litres are suitable for single-person households or occasional use. For offices or families, models with a capacity of 1 litre or more are more practical. The device's dimensions are particularly relevant for users with limited counter space. A small coffee machine can easily fit into compact kitchens or onto a desk.
Some models, often referred to as a coffee machine for capsules and grounds, offer the ability to use loose coffee grounds in addition to capsules via special adapters. This provides a flexible alternative for users who occasionally want to brew their own coffee blend without sacrificing the convenience of a capsule machine.
The following models have been selected based on their technical specifications and practical value.

1. What is the difference between Nespresso Original and Vertuo? The Nespresso Original system operates with high pressure (up to 19 bars) and is primarily designed for preparing Espresso and Lungo. The Nespresso Vertuo system uses a patented centrifugation technology (Centrifusion), where the capsule rotates. It uses a barcode to recognise the capsule type, allowing it to prepare a wider range of cup sizes, from Espresso to large coffee mugs. The capsule shapes of the two systems are not compatible with each other.
2. Can any capsule be used in any capsule machine? No, compatibility is a crucial factor. Most capsule systems are proprietary, meaning they only fit capsules from the respective manufacturer or third-party capsules specifically marked as compatible. Machines like the HiBREW H1C are an exception, as they are designed for different standards using the included adapters.
3. How important is the pump pressure in a capsule machine? Pump pressure is particularly relevant for preparing espresso. A pressure of 9 bars is considered the minimum to effectively extract the oils and flavours from the coffee grounds and create a dense, stable crema. Most high-quality machines operate between 15 and 20 bars, which ensures a high-quality extraction. For coffee drinks that are not espresso-based (like some Vertuo varieties), pressure is less critical than other brewing parameters.
