Introducing the Orb One, a coffee maker that redefines the art of brewing. This sleek, minimalist device is a coffee maker and a statement piece for your kitchen. Its unique, orb-shaped design is a fusion of aesthetics and functionality, promising to be a conversation starter at any gathering. This post is an update on a great little coffee maker.

The Orb One is engineered for precision, always delivering a perfect cup of coffee. Its patented brewing system ensures optimal extraction of coffee flavors, while the adjustable settings let you customize your brew strength to your liking. Whether you prefer a robust espresso or a mellow Americano, the Orb One has you covered.

But the Orb One isn’t just about great coffee. It’s also about sustainability. Made from high-quality, durable materials, it’s designed to last, reducing the need for disposable coffee pods and filters. Plus, its energy-efficient design uses less power than traditional coffee makers, helping you reduce your carbon footprint.

Experience the future of coffee brewing with the Orb One. It’s more than a coffee maker – it’s a revolution in your cup.

The Orb One coffee maker is a  uniquely designed, single-serve (8oz) stovetop coffeemaker that the designers say can change the coffee type by using a different coffee grind and water ratio.

You can make your favorite cup of coffee from drip to espresso and keep each style’s characteristic richness and flavor.

The Orb One was initially only available on Kickstarter. The design team had a goal to raise $250,000 for the project but actually received over $388,000. This is the mark of a good start-up!

This unusual-looking coffee maker is now in production and available from Crucial Detail.

Orb One: Stovetop Coffeemaker

How does the Orb One Work?

The Orb One works like a Moka pot where vapor pressure forces hot water up through ground coffee. The designers don’t mention the pressure generated during brewing, but I guess it would be about 1 to 2 Bar like a Moka pot.

The Orb One has a squat hemispherical shape and was designed by Chicago-based Crucial Detail. It looks weird but smart.

It can be used on a traditional stovetop, including a gas burner, electric stove, induction stove, ceramic plate, or camping stove.

The brew chamber can take 14 to 16 g of ground coffee, and the boiler holds at least 8 oz of water.

Consequently, you can adjust the coffee grind and the ratio of coffee to water to experiment with different brewing styles.

The Orb One coffee maker is not an espresso machine and can’t generate a pressure of 7 to 10 Bar to make an espresso. However, the designers say that it can make a coffee with the flavor characteristics of espresso.

Temperature, Turbulence, and Time  Regulation

Controlling variables is key to consistency. In the case of coffee, the critical variables are often described as the “three Ts”: Temperature, Turbulence, and Time.

Temperature Regulation

The designers say its internal structure prevents over-extraction by coupling a temperature-regulating solid stainless steel shower head with a ‘laser-pulse-drilled filter’ that allows for ‘perfect infusion’.

What the heck does this mean?

The stainless steel shower head was designed to be a heat sink and cools the boiling water to the ideal temperature of about 91ºC (195ºF) before it enters the ground coffee.

Agitation by flowing water, stirring, and outgassing creates turbulence within the coffee grounds. This improves the extraction of flavor characteristics of the coffee. Essentially, turbulence separates the coffee grounds to make them more accessible for water extraction.

The Orb One’s showerhead was designed with hole size and geometry to avoid channeling, avoid dry spots, and create maximum turbulence.


Extraction of coffee depends on the contact time of hot water with the coffee grounds. You have full control of the brew time with the Orb One. You simply leave it brewing for as long as you desire.

The coffee grind size and the brew time determine the type of coffee you want to make.

A coarse coffee grind with a large volume of water will give you a large volume similar to drip coffee. In contrast, a fine grind with a small volume of water will yield an intense, viscous coffee, similar to espresso.

You can adjust and experiment with grind size and brew time to give you the desired taste.

The secret is in the grind!

Easy to use & High Precision

It is very easy to clean the Orb One. Simply knock out the coffee cake and rinse!

The Orb One has a unique permanent stainless steel filter. This holds coffee solids in place during extraction.

The designers worked with a Swiss laser manufacturer to develop a specialized technique to make the filter extremely precise and cost-effective. The laser-pulse-drilled stainless steel contains holes that are 250 microns in diameter, held to a 10 micron tolerance.

Pros and Cons of Orb One Coffee Maker


  • Flexibility: The Orb One offers the ability to change the coffee type by simply adjusting the grind, allowing you to brew anything from a pour-over to an espresso
  • Unique Design: The orb-shaped design is not only aesthetically pleasing but also functional, preventing over-extraction or burnt-tasting coffee
  • Precision: The device includes a solid stainless steel “shower head” that regulates brew water to the perfect temperature and a laser-drilled filter that controls water flow with unrivaled consistency.
  • Versatility: It works well on various heat sources, including gas burners, electric stoves, induction, ceramic plates, and camping stoves.
  • Control: The Orb One allows you to control the “three Ts” of coffee brewing: Temperature, Turbulence, and Time, enabling you to tailor your coffee to your exact preferences.


  • Single-Serve: The Orb One is a single-serve coffee maker, which may not be ideal for those who want to brew multiple cups simultaneously.
  • Learning Curve: Given its unique design and features, there may be a learning curve in understanding how to adjust the grind and settings to achieve the desired coffee type and strength.
  • Time-Consuming: As a stovetop coffee maker, it may take longer to brew coffee than electric drip coffee makers or pod-based systems.
