Pure taste, clean lines. Comes apart by hand. Not because it breaks — because it's built to last. The lid seal lifts out and swaps in seconds. The band separates for a proper clean, not a rinse and hope. Every part that wears is a part you can replace.

What makes KeepCup reusable glass cups sustainable?

The tempered glass range launched in 2014, pairing break-resistant tempered glass with a silicone or cork grip. It needs just 24 uses to beat the environmental impact of 1,000 disposable cup uses.

  • Break-resistant tempered glass: High-quality tempered glass containing 25% recycled material, paired with a silicone or cork grip.
  • Environmental payoff in 24 uses: The lowest break-even point in our range — glass carries nothing forward, so there is no taint and no transfer.
  • Australian-designed, UK-assembled: Hand-assembled in the UK since 2011 by an accredited Living Wage employer, and tested for food safety.

The 24-use figure comes from our independent peer reviewed 2018 Life Cycle Analysis.

Across the range: modular parts you can replace individually, single-material components that separate at end of life, independent food-safety testing, 100% recycled paperboard packaging, and made by a certified B Corp that gives 1% of global revenue to environmental causes.

What makes KeepCup glass cups worth choosing?

From the world’s original reuse pioneers, KeepCup’s glass range combines premium materials, clean lines, and daily practicality. Every cup replaces hundreds of single-use cups — proof that small steps make a big difference.

With splashproof lids and sleek, barista-standard design, these cups are as practical as they are beautiful. Whether you choose the timeless Brew Cork or the classic Brew Glass, you’ll taste coffee the way it was meant to be — pure, balanced, and waste-free.

Choose your finish — cork or silicone — and your favourite lid style. Then make your coffee, your way. Because when sustainability looks and feels this good, reuse becomes second nature.

What is the KeepCup Brew Cork?

The KeepCup Brew Cork is the reusable glass coffee cup that started a movement. Hand-assembled in the UK 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 café-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 café-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 favourite 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.
