Depending on your preferences and area of use, a different tool is the right one. The main differences between the various portafilter machines are their boiler and pump.
The boiler contains the water for making espressos and the steam for foaming the milk. A heating element brings the water to the ideal temperature and keeps it at as constant a level as possible. The size of the boiler determines the capacity of the water and steam supply.
A single boiler supplies the brewing group and steam lance at the same time. This means that milk cannot be foamed at the same time when preparing espressos. The optimum temperature for the brew group is around 90°C, and much more than 100°C is needed to produce steam. The change from brewing water to steam is only possible after heating up. Single-circuit systems are therefore the right choice for espresso lovers.
Water is heated in a closed boiler. A layer of water forms in the lower part of the boiler and a layer of steam in the upper part. A pressostat keeps the pressure at about 0.8-1.2 bar. The temperature here is about 125°C. A somewhat thicker pipe is laid through the "water section" of the boiler, through which a pump pumps cold fresh water for espresso. As the fresh water passes through the heat exchanger, it is heated to the desired brewing temperature of around 95°C by the surrounding boiler water. The brewing temperature is thus set indirectly via the boiler pressure. Steam for milk froth can be taken from the upper part of the boiler, and hot water for making tea or warming cups from the lower part. The heat exchanger is designed so that the water remains in the heat exchanger at the optimum flow rate until it reaches the right temperature.
As the name suggests, a dual boiler consists of two separate boilers for brewing water and steam. Thanks to this separation, espressos and steam can be drawn simultaneously without fluctuations in pressure or temperature.
The manufacturers of modern espresso machines rely on electrically operated pumps. Whereas in the past a lot of skill was required to operate lever machines, today constant pump systems ensure perfect espressos.
The vibration pump is mainly used in the household segment. The pump is cheaper and takes up less space than the rotary pump. On the other hand, it is louder than the other system.
The rotary pump has a higher capacity than the vibration pump. It is correspondingly more expensive. Its smooth running and robustness are particularly appreciated in the catering trade or by discerning home baristi.
Which espresso machine is the right one? The easiest way to start is to sort by boiler. Which system meets your individual requirements: Single-circuit, dual-circuit, dual boiler?
For the rest of the selection process, look at features such as espresso machines with P.I.D. (Proportional-Integral-Derivative Controller). With this complex control circuit, the temperature of the water in the boiler is constantly controlled, ensuring optimal results.
Finally, you decide on your preferred pump system.
Don't forget: at least as important as the right espresso machine is the right grinder. Like the machine, an even grind is one of the "four M's" for a perfect espresso.
Einkreissysteme zeichnen sich dadurch aus, dass sie nur über einen einzigen Boiler verfügen, der sowohl die Brühgruppe als auch die Dampflanze mit Wasser versorgt.
Dies bedeutet, dass du während der Espressozubereitung nicht gleichzeitig Milch aufschäumen kannst. Das liegt daran, dass die optimale Brühtemperatur für Espresso bei etwa 93°C liegt, während für die Dampferzeugung Temperaturen weit über 110°C erforderlich sind.
Der Wechsel zwischen der Zubereitung von Espresso und dem Milchschäumen erfordert daher eine gewisse Wartezeit, in der der Boiler auf die jeweils benötigte Temperatur erhitzt wird. Diese Systeme sind ideal für diejenigen, die sich auf die pure Espressozubereitung konzentrieren und keinen Wert auf gleichzeitiges Milchschäumen legen.
Vorteile
Nachteile
Zweikreissysteme bieten eine deutlich höhere Flexibilität. Hier wird das Wasser in einem geschlossenen Boiler erhitzt, wobei sich im unteren Bereich des Boilers heisses Wasser und im oberen Bereich Dampf sammelt.
Ein Pressostat sorgt dafür, dass der Druck im Boiler bei etwa 1,0 bis 1,3 bar gehalten wird, was einer Temperatur von rund 105°C bis 128°Centspricht.
Das Besondere an Zweikreissystemen ist der integrierte Wärmetauscher: Ein dickes Rohr durchzieht den Wasserbereich des Boilers und dient als Wärmetauscher, durch den eine Pumpe kaltes Frischwasser für den Espressobezug pumpt. Während das Wasser durch diesen Wärmetauscher fliesst, wird es auf die ideale Brühtemperatur von etwa 93°C erhitzt.
So ermöglicht dieses System, dass du gleichzeitig Espresso zubereiten und Milch aufschäumen kannst, ohne dass es zu Wartezeiten kommt.
Vorteile
Nachteile
Dualboiler-Systeme sind das Nonplusultra unter den Espressomaschinen. Wie der Name schon sagt, verfügen diese Maschinen über zwei getrennte Boiler: einen für das Brühwasser und einen für den Dampf.
Diese vollständige Trennung ermöglicht es, Espresso und Dampf gleichzeitig zu beziehen, ohne dass es zu Schwankungen in Druck oder Temperatur kommt.
Ein Dualboiler-System bietet maximale Kontrolle und Flexibilität, da du die Temperatur für das Brühwasser und den Dampf unabhängig voneinander einstellen kannst. Dies ist besonders wichtig für Baristas, die höchste Präzision bei der Zubereitung ihrer Getränke verlangen.
Vorteile
Nachteile
Neben dem Boiler ist die Pumpe ein weiteres entscheidendes Element einer Espressomaschine. Moderne Maschinen setzen auf elektrisch betriebene Pumpen, die für eine konstante und präzise Wasserzufuhr sorgen, was für die Qualität des Espressos von entscheidender Bedeutung ist.
Vibrationspumpen sind die häufigste Wahl in Haushaltsmaschinen. Sie sind kompakt, preisgünstig und zuverlässig.
Die Pumpe erzeugt den notwendigen Druck durch schnelle, pulsierende Bewegungen, was jedoch zu einer höheren Geräuschentwicklung führt. Vibrationspumpen sind ideal für den Heimgebrauch, wo Platz und Kosten eine Rolle spielen. Sie bieten eine gute Leistung, haben jedoch nicht die Langlebigkeit und Laufruhe von Rotationspumpen.
Vorteile
Nachteile
Rotationspumpen sind das Nonplusultra unter den Pumpensystemen und finden sich hauptsächlich in professionellen Maschinen oder bei sehr anspruchsvollen Home-Baristi.
Diese Pumpen arbeiten leise und gleichmässig und bieten eine höhere Kapazität sowie eine längere Lebensdauer. Rotationspumpen können grössere Mengen Wasser mit konstanter Geschwindigkeit fördern, was sie zur bevorzugten Wahl in der Gastronomie macht, wo hohe Leistungsanforderungen und Zuverlässigkeit gefragt sind.
