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 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.

Is the Brew Cork dishwasher safe?

To protect the natural cork band, we recommend handwashing your Brew Cork. The glass is toughened and dishwasher safe, but the cork band can lose its shape with excess water or heat. A gentle rinse keeps it looking its best for years. If you do need to remove the band this is the best way to do it.

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.

Are reusable glass coffee cups safe for hot drinks?

Yes. KeepCup glass cups are made from heat-resistant toughened glass designed to handle both hot and cold drinks, and the cork or silicone band protects your hands while keeping the warmth in the coffee.

On how long it stays hot: glass holds heat well for shorter coffee styles like flat whites, cappuccinos and piccolos — the drinks it was designed around. For longer-lasting warmth, the Longplay adds a double wall and a removable sleeve, insulating without much extra bulk.

Avoid thermal shock: do not take glass from the freezer to boiling water, or the reverse.

What’s the difference between cork and silicone bands on KeepCup glass cups?

Both offer a secure grip and heat protection. The natural cork band is sourced sustainably and adds a soft, organic feel, while the silicone band is lightweight, flexible, and dishwasher safe. Choose cork for a warm, tactile experience or silicone for easy cleaning — either way, it’s reuse done right.

The Cork band has more thermal insulation and a wider grip so we offer with 16oz (450ml) glass. We only offer the silicone band in 12oz size with a glass base.
