Beautifully Made, Brilliantly Simple

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 favorite lid style. Then make your coffee, your way. Because when sustainability looks and feels this good, reuse becomes second nature.

Do glass reusable coffee cups keep drinks hot?

Glass retains heat well for shorter coffee styles like flat whites and cappuccinos. For longer-lasting warmth, choose the KeepCup Longplay with a double-wall design that insulates without adding bulk.

Can I put my reusable glass coffee cup in the dishwasher?

The glass and silicone components are dishwasher safe (top rack only). If your cup has a cork band, handwash it gently to protect its shape and finish. Designed for daily use, each KeepCup glass cup is easy to clean and even easier to love.

Is the lid on a KeepCup glass coffee cup leakproof?

KeepCup lids are splashproof, not fully leakproof — perfect for sipping on the go, not for tossing in a bag. The press-fit design with sipper plug prevents spills while giving you that café-style drinking feel.

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.

Are reusable glass coffee cups safe for hot drinks?

Yes — KeepCup glass cups are made from heat-resistant, toughened soda-lime glass that’s designed to handle both hot and cold drinks. Paired with a cork or silicone band, they protect your hands while keeping the warmth where it belongs — in your coffee.

What’s the best reusable glass coffee cup with a lid?

The KeepCup Brew Cork and Brew Glass ranges are made from durable tempered glass and come with splashproof, press-fit lids that make drinking easy on the move. Designed for coffee purists who want clarity, quality, and comfort, they’re barista-standard and made to last.
