What is the KeepCup Brew Cork?

The KeepCup Brew Cork is the reusable glass coffee cup that set the standard. Hand-assembled and loved worldwide, it pairs durable, tempered glass with a natural cork band for comfort and grip. Sourced sustainably from Portugal’s wine industry, each cork band is unique — a nod to craftsmanship, not mass production.

Perfectly sized for barista espresso machines, Brew Cork delivers a cafe-quality experience with every pour. It’s beautiful to hold, easy to clean, and made to last. Since 2014 and counting, this cup has been the global benchmark for sustainable design and simple reuse — the original, and still the best.

Why is the Brew Cork Coffee Cup so popular?

Brew Cork is one of KeepCup's most iconic and best-selling products. Cork is a natural product, and the band is made from the offcuts of cork production from the wine industry. Its natural, insulating, biodegradable and feels lovely to hold and to use.

Why choose the Brew Cork over other reusable cups?

The Brew Cork combines cafe-quality glass with a soft cork band that feels great in your hand and keeps heat away from your fingers. It’s barista-standard, fits perfectly under espresso machines, and has been a customer favorite for over 10 years for its simplicity, style, and sustainability.

What is the KeepCup Brew Cork made from?

The KeepCup Brew Cork is made from durable, tempered soda-lime glass with a natural cork band for comfort and grip. The cork is sourced sustainably in Portugal and repurposed from wine industry by-products, making every cup uniquely textured and responsibly made.

How do I clean and care for my Brew Cork KeepCup?

Brew Cork is made from glass and natural cork, both renewable and recyclable materials. Each cup replaces hundreds of disposable coffee cups, helping you make a measurable difference with every brew.

Rinse the glass and lid after each use, and handwash the cork band gently with warm water. Avoid soaking the cork or exposing it to the dishwasher. With proper care, your Brew Cork will stay beautiful and functional for years.

Can I put my cork band in the microwave?

The cork band is a natural product made from the bark of the cork tree. Use in the microwave can dry out the band and cause it to crack and crumble. A quick rinse or gentle handwash is best.
