Microwave Coffee Maker Piamo Brews a Cup in 30 Seconds

If you've ever wanted a single cup of coffee—fast—and without a machine, a pod, or a long wait, there's now a device that does exactly that using your microwave. No electricity, no complex setup, just hot water, coffee grounds, and 30 seconds. But how does it actually work? And is the coffee any good?

Piamo is a four-piece microwave coffee system that brews a cup of coffee in around 30 seconds. Just add water, insert coffee grounds, and heat in the microwave. The steam forces water through the grounds, delivering a freshly brewed cup quickly and easily—all without a traditional coffee machine.

What Is Piamo?

Piamo is a compact, microwave-powered coffee maker developed jointly by German company Gemodo Coffee and design studio Lunar Europe. Unlike traditional electric coffee machines, Piamo doesn’t use electricity to heat or pump water. Instead, it’s made up of just four parts: a cup, a water tank, a filter, and a filter lid. Designed to fit inside a standard microwave, it uses the appliance’s heat to brew coffee in seconds.

How Does Microwave Coffee Brewing Work?

The brewing process is simple but effective. First, you fill the water tank with fresh water. Then, you place either loose coffee grounds or a coffee pod into the filter. After securing the filter lid, you stack all the parts together—the water tank sits atop the filter, with the cup at the bottom. Give it a gentle shake to ensure everything is seated properly, then place the entire assembly in the microwave.

When microwaved, the water in the tank heats up and turns to steam. The increasing pressure from the steam forces the hot water downward through the coffee grounds in the filter. This downward flow extracts the coffee, which drips into the cup below. The whole process takes approximately 30 seconds, depending on your microwave’s power.

Why Choose a Microwave Coffee Maker?

Piamo offers a few clear advantages:

• Speed: Coffee is ready in about 30 seconds.
• Simplicity: No plugs, no pumps, no filters other than the included one.
• Ease of Cleaning: All parts are removable and dishwasher-safe or easy to rinse by hand.
• Portability: Its compact, modular design makes it easy to store or take on trips.

How to Use Piamo Step by Step

Here’s the exact process for making coffee with Piamo:

1. Fill the water tank with the desired amount of fresh water.
2. Place your ground coffee or coffee pod into the filter.
3. Attach the filter lid securely.
4. Assemble the pieces: place the filter inside the cup, then stack the water tank on top.
5. Gently shake the assembled unit to help the coffee bed settle.
6. Place the full stack in your microwave.
7. Heat for around 30 seconds (timing may vary with microwave wattage).
8. Carefully remove the unit (it will be hot) and pour your freshly brewed coffee.

What Kind of Coffee Can You Use?

Piamo works with both loose coffee grounds and coffee pods. Since the brewing relies on hot water passing through the coffee under pressure from steam, you can use any standard grind suitable for filter or drip coffee—typically a medium grind similar to what you’d use in a pour-over or automatic drip machine. Avoid extra-fine espresso grinds, which may clog the filter or slow extraction too much.
