About this project
"Special Thanks to Patrick Calderon and Johanna Calderon-Dakin for providng us with their invaluable PR and crowdfunding expertise" - Curt and Vincent, inventors of the Nomad
"...this light-weight, hand crank-powered device means the best espresso is always right at your finger tips." - Beth Buczynski, EarthTechling, TreeHugger
"The Nomad is the Greenest Espresso Machine Ever" - Dennis Burger, Technology Tell
The Nomad™ is a revolutionary portable espresso machine. If you are a coffee lover you’ll love having the Nomad with you wherever you go. It makes the highest quality espresso, and it does this anywhere you have coffee and hot water. The Nomad is clean and green. It needs no electricity, batteries, or high pressure gas cartridges. There are no expensive wasteful coffee pods or capsules to be discarded.
The Nomad is perfect for everyday use at home in the kitchen or garden. It's the ideal espresso machine to use at work or in the field. The Nomad is a great companion for your RV, camping, and boating lifestyle. Whether you take it with you fishing, or hunting, or on a business trip the best espresso is right at your finger tips. The possibilities are endless.
The Nomad was inspired by the classic hand operated lever machines which remain the benchmark of quality espresso machines. We simplified and miniaturized the large, complex lever machines and created a portable device that’s very easy to use. The Nomad is the size of a 15 cm cube, weighs 1.1 kg, and requires no electricity. With very little effort the Nomad produces 9 bars of pressure and like the classic lever machines users have direct control over the water temperature, pressure, flow rate, and volume. Skilled coffee hobbyists and experts will enjoy playing with these variables. In addition, The Nomad is equipped with a proprietary True Crema Valve™ which compensates for coarser grounds and tamping variations. When used with the True Crema Valve anyone can make great espresso and coffee without having expensive grinding equipment and extensive training.
Just pack ground coffee, add hot water, and actuate the pump lever.
The following video shows that Nomad pulls great espresso when used without the True Crema Valve. In this way Nomad works like other high quality machines, requiring proper grinding and tamping to make perfect espresso. We use the Nomad prototype without the TCV on a daily basis, with well calibrated grounds out of a commercial Italian grinder or a hand-cranked German mill.
The following video shows, with the True Crema Valve, Nomad makes great espresso even with coarser grounds and imperfect tamping technique. This means that, users can make quality espresso with little effort the very first time they use the Nomad and every time thereafter. The True Crema Valve system is a proprietary technology researched, developed, and perfected by UniTerra Inc. It is not seen in any other espresso machine.

Risks and challenges
All elements of the Nomad have been implemented in working prototypes and tested thoroughly over the last two years. Literally thousands of shots of espresso have been made during these tests to verify materials, durability, pumps, valves, brew chambers, fluid flow and beverage quality. A complete CAD design by a professional industrial design firm has been completed and refined. From that final design a complete fully functioning prototype has been professionally machined and tested by us daily for months (shown in this video). We are now ready to create tooling and move into production. We have tooling and production quotations from leading contract manufacturing firms. The funds raised from this Kickstarter project will be used to create that tooling and produce the first production run (1,000 units). Based on these quotations and our two year experience with the technology we conservatively estimate 4-6 months from beginning tooling to first production run completion.Learn about accountability on Kickstarter
Output volume is controlled by user pumping action. You can pump a single shot (30 ml), a double shot (60 ml) or up to the full tank capacity of 300 ml (10 oz) for a full cup of coffee.
The best results will be achieved with very fine and precise grounds intended for espresso machines. However, great results can also be achieved with various grounds from any coffee grinder, or vacuum pack coffee widely available in super markets (Lavazza, Illy). The Nomad's True Crema Valve™ compensates for the variation of the fineness of coffee grounds and packing pressure, ensuring optimal emulsification of beneficial oils in coffee beans. Unlike the common double-walled pressurized filter basket, True Crema Valve™ does not aerate, or foam up the coffee.
We recognize that pods and capsule machines are convenient and easy to use. However, highest quality espresso can only be achieved by hand packing of fresh coffee grounds. The present Nomad aims at producing the best espresso possible, so it only works with ground coffee, the fresher the better. This provides the widest selection of coffee possible at much less cost than buying disposable pods and capsules.
The Nomad is manually powered. It requires no electricity, batteries, or CO2, N2O cartridges. Just add coffee, hot water, and actuate the pump lever.
Multiple patents are pending in both the U.S. and internationally.
What materials are used in the construction of the Nomad? Are they safe in contact with hot water and food grade?
All materials that come in contact with hot water and coffee in Nomad are food grade and rated for high temperature applications. These include Polypropylene, Polyoxymethylene (POM), EPDM, silicon, stainless steel, and brass.
The basket size in Nomad is the same as the La Pavoni Europiccola two cup filter basket P-68. It is 49mm in spec but measures 50mm exact. It is enough for a crema rich double shot espresso.
Yes. The True Crema Valve can be easily removed. Without the True Crema Valve, like any other professional or commercial espresso machine the results will depend upon proper calibration of the grind and skilled tamping technique. The True Crema Valve reduces the requirements of expensive coffee mills and skilled technique. This means now everyone can pull a great shot of espresso with the Nomad.
To accommodate early adopters who desire a second coffee drawer shipped together with the Nomad in August, 2013, you can add $55.00 to your pledge amount and note the extra amount is for a second drawer when we communicate with you for shipping details. With two coffee drawers you can load and pack both drawers with coffee and then after making the first espresso swap the drawers and make a second. This allows you to make two high quality double shot espresso drinks in about two minutes. This coffee drawer is a complete assembly of drawer, pressure chamber, filter basket, and True Crema Valve™
With proper pumping technique it is easy to maintain the brew pressure within the optimal range of 8 to 10 bars, or higher if desired. The technique is easy to master due to ergonomic design elements which make the pump and lever easy and comfortable to operate.
Thermal requirements were at the center of our design considerations and we have engineered the Nomad to keep water hot enough for great espresso making. Guidelines from the Istituto Nazionale Espresso Italiano state that the entry water pressure is 9 ± 1 bar and the entry water temperature is 88 ± 2°C (67 ± 3°C in the cup). The Nomad's thermal design is based on two central concepts of low thermal mass and low thermal conductivity. The selection of materials that come in contact with the hot water in the Nomad minimize heat absorption and dissipation. The result is that, if filled with water at near boiling temperature (98 degrees C +/- 1) the entry temperature of water into the brewing chamber is 88 ± 2°C and the coffee temperature in the cup is 67 ± 3°C. These numbers depend on the ambient temperature. With a cold machine, we suggest pre-warming the Nomad by filling it with hot water and pump a blank shot. Tamp the coffee, dump the remaining water out first then fill it again with boiling water to start pulling the first shot. These measures of low conductivity design and insulation not only reduce the loss of heat, but also ensure that the exterior of the Nomad never becomes hot to touch during operation.
