World’s First Disposable Mobile Coffee Maker Lets You Brew On the Go

You’re traveling, hiking, or just away from home when the craving hits: a clean, properly extracted cup of coffee. But there’s no café, no kettle, no grinder—and certainly no way to carry a full coffee setup with you. What do you do when you need a proper brew and all you have is hot water and a few minutes?

The answer is Grower’s Cup: a single-use, portable coffee brewer that works like a tea bag and makes filtered coffee in minutes. One pouch costs between $1.70 and $2.50, holds 18 grams of coffee, and makes two cups with 300ml of hot water. No machine. No mess. Just pour and drink.

What Is Grower’s Cup?

Grower’s Cup looks nothing like a traditional coffee machine. In fact, calling it a “mobile coffee bag” might be more accurate. It’s a single-use pouch that works similarly to a tea bag. You pour hot water over the coffee grounds inside, let it steep, and filtered coffee flows through a built-in filter into your cup. It’s designed to deliver a clean cup without any sediment or sludge—just like a proper filter brew.

Why Was It Invented?

The idea came to Ulrik Rasmussen, a 46-year-old from Middelfart, Denmark, during a very relatable coffee emergency. One morning, he went to make coffee only to find he had no filter left. Frustrated and desperate for his morning brew, he spotted some tea bags and wondered: why not brew coffee the same way? He emptied a tea bag, filled it with coffee grounds, and the concept for Grower’s Cup was born. That moment of inspiration led to nine years of research and development.

Ulrik’s goal was simple yet ambitious: create a single solution that combines the convenience of a tea bag with the quality of a French press-style filtered coffee. The result is a product that feels as easy as making tea but delivers a clean, filtered cup every time.

How Does It Work?

Each Grower’s Cup pouch contains 18 grams of ground coffee. To brew, you simply:

• Add approximately 300ml of hot water (ideal brewing temperature not specified, but typical for filter coffee is 90–96°C)
• Let it steep for a few minutes (exact brew time not stated, but similar to tea or pour-over methods)
• Watch as filtered coffee flows through the integrated filter into your cup

The design allows for a clean extraction, separating the coffee grounds from the brewed liquid—so there’s no need for a separate filter or complex setup. Each pouch makes roughly two standard servings. The entire process is meant to be as intuitive as brewing tea, but the output is a proper filtered coffee experience.

How Many Varieties Are Available?

Grower’s Cup is available in 12 different coffee varieties. While the source doesn’t specify exact origins or roast levels, the range suggests options for different taste preferences—from light to darker roasts. Each pouch is priced between $1.70 and $2.50, aiming to offer both convenience and choice for coffee drinkers on the move.

Frequently Asked Questions

How does Grower’s Cup compare to other portable coffee options like instant or capsules?

Unlike instant coffee, Grower’s Cup uses real ground coffee and filters it through an integrated system, delivering a filtered brew rather than a dissolved powder. It’s also not a capsule system like Nespresso—you don’t need a machine. It’s more comparable to a single-serve pour-over in a bag, but without requiring any additional equipment.

How much coffee is in each pouch and how many cups does it make?

Each Grower’s Cup pouch contains 18 grams of coffee and makes approximately two cups when brewed with 300ml of hot water. The exact yield may vary slightly based on your pour technique and water volume.

What’s the brewing process like? Do you need special equipment or skills?

No special equipment or barista skills are needed. You pour hot water into the pouch, let it steep, and filtered coffee comes out the bottom. It works similarly to a tea bag but is designed to mimic a filtered coffee experience. No mug, filter, or machine is required.

How long did it take to develop Grower’s Cup?

The product took Ulrik Rasmussen nine years to develop, starting from the initial idea inspired by a tea bag. It has just been launched in the UK and sold out quickly after release.
