Redefining the craft of espresso making

STRIETMAN, founded by Wouter Strietman, is a company developing and designing coffee related products for the household environment. These products excel in quality and craftsmanship. Simple and reliable engineering, built to last forever. The Strietman espresso machines are produced in The Netherlands using a small-scale industrial production line. The machines are carefully assembled and tested. The art of coffee making is brought back to its essential origin. The technology involved has been simplified and made visible in every detail. The machine is operated by hand and for full quality control you can rely on the judgement of your own senses.

Perfection, simplicity and transparency have been the leading principles during development. To safeguard reliability, security and sustainability, we prioritize CE certification and therefore our machines comply with the European standards for these devices. Strietman aims to appeal to users looking for the best possible taste from a machine that looks great because of its build quality and durable engineering. Celebrate the coffee ritual, the joy of a perfect espresso being a quality part of life. Focus on the pure simplicity, having a piece of solid traditional engineering to allow a sensory experience of coffee preparation.

The Strietman Brew-group

Most espresso machines carry quite complicated electromechanical systems but the Strietman brew group uses a simple and robust lever mechanism. This technology —developed in post-war Italy— gives you absolute control over the extraction process.

Controlling the extraction process.

The coffee bean is a natural product and as such it is subject to subtle changes over time.  Preparing the perfect espresso involves a continuous interplay between coffee bean, grinder and espresso machine. If during your extraction of an espresso you feel that the first coffee drops appear a little later and slower than expected, you can easily adapt the extraction process by pulling the lever down just a little bit harder. After finishing the shot, you will probably adjust the grinder to a slightly coarser setting but you just might also experience a new and deeper taste quality in the stronger brew.

Mastering the brew.

As the palm of your hand leans on the lever and the espresso starts to flow, you will find that there is no system offering you more direct control. Furthermore, the water temperature on the Strietman brew-group is easily adjustable. This is very convenient because an Ethiopian bean could be most delicious if brewed on 88ºC whereas a robust Brazilian may sometimes be best extracted at 94ºC. The temperature on the Strietman brew-group fluctuates within a 3ºC differential, so your ideal brew-temperature will never be more than -1.5c/+1.5 off.

Bimetal copper / stainless steel inside dome

The new bimetal stainless steel inside dome is a thrilling new feature which fits all Strietman espresso machines.

The dome is the upper part of the Strietman brew-group. The so-called open boiler.


Copper is the best metallic conductor apart from silver, which explains why electricity cables are made of copper. Copper is also excellent for maintaining heat, so it keeps the water inside the espresso machine very stable.

As long as your water has a normal PH level the all copper dome works fine. The downside however is that you need to keep an eye out on your water quality. When water has a high acidic level it will react with the copper, this can leave oxidation.
Next to that the copper inside the dome is also sensitive to stains.

 bimetal dome

The optional bimetal stainless steel inside dome is an excellent choice for those who prefer easy maintenance and care-free use.

The bimetal is developed by Falk Culinair, a Belgium copper pan manufacturer. The material consists of a heavy copper plate on which a 200 micron (0,2mm) fine layer of stainless steel is anchored using a pressure of 850 tons/cm². The result is a metallic “intercristalline” connection.

Furthermore we’ve increased the thickness of the bimetal dome wall which adds 0.5ºC to the thermal stability of the machine.
