The World’s First Disposable Mobile Coffee Maker

You’re out hiking, commuting, or just away from home when a strong craving for a clean, smooth cup of brewed coffee hits. You don’t have a cafetière, no café is in sight, and carrying a full brewing setup is out of the question. What if there were a way to make proper filter coffee without any equipment—just like you’d steep a tea bag?

The answer is the Grower’s Cup: the world’s first truly portable, single-use coffee brewer. One pouch, hot water, and a couple of minutes is all you need to make two cups of filtered coffee, wherever you are.

What Is Grower’s Cup?

Grower’s Cup looks nothing like a traditional coffee machine. In fact, designer Ulrik Rasmussen calls it more of a “mobile coffee bag.” It works similarly to a tea bag: you pour hot water over the pouch, let it brew, and filtered coffee drips directly into your cup. No machines. No filters. No mess.

Why Was It Invented?

Ulrik Rasmussen, a 46-year-old from Middelfart, Denmark, came up with the idea one morning when he wanted coffee but had no filter left in his machine. Frustrated, he spotted some tea bags and wondered: why not brew coffee the same way? That moment sparked nine years of research and development, culminating in the launch of Grower’s Cup in the UK, where it quickly sold out.

How Does It Work?

Each Grower’s Cup pouch contains 18 grams of ground coffee. You add 300 ml of hot water, let it brew, and the dual-layer design filters the grounds, delivering two servings of filtered coffee. The whole process mimics a French press-style immersion combined with a built-in paper filter, all wrapped up in a tea-bag-like format.

The coffee is pre-measured and pre-packaged, making it effortless to use. Just pour, wait, and drink. The special filter inside ensures no grounds escape into your cup, giving you a clean, café-quality extraction experience, even on the move.

Flavor & Variety

Grower’s Cup offers 12 different coffee varieties. Each pouch is designed to deliver a balanced cup similar to what you'd expect from a good drip or French press brew. While the article doesn't specify exact roast levels or origins, the design targets clarity and smoothness, ideal for on-the-go palates.

Prices range from $1.70 to $2.50 per pouch, making it an affordable alternative to café coffee when you're away from home. The focus is on convenience without sacrificing flavor integrity.
