The Brew Flask genuinely looks after the planet. Every time you fill it, Ocean Bottle will take another plastic bottle from the ocean.
It'll keep your drink piping for 2 to 3 hours and warm for up to 6 hours.
At 350ml it'll fit into most rucksacks or office bags and it won't leak. What's not to love?
The New Peak Brew is for you.
The new and improved Peak Brew combines all that we love about the Brew Flask and mixes it up with the high end Peak range.
The result is a 590ml flask that can keep your hot drinks hot for up to 9 hours. It's still slim and can fit in a car cupholder or bag sleeve and carries the same environmental credentials as the original.
We think so if you want a reusable coffee flask that’s compact, dependable, leakproof and genuinely well designed for daily life. It isn’t the cheapest option, but the build quality and long-term durability are what make it worth it.
We think so. It's pretty neat making it ideal for external bag sleeves that take bottles. It's 170mm tall and 68mm wide. And it's anti-leak seal means you can safely tuck it inside a bag too.
Yes it is. 100% dishwasher safe at temperatures up to 60c. For day to day use we recommend just giving it a quick wash with warm soapy water.
BPA-Free plastic, Silicone Rubber, Ocean Bound Plastic and 90% recycled Stainless Steel.
All Brew Flasks are backed up with a 10 year repair or replacements scheme from Ocean Bottle. In case of manufacturing defect or accidently broken parts.
We get asked this a lot! So we made a video. Brew Flask Heat Test
Roughly talking it only loses about five degrees an hour. If you don't use milk it will stay hot for longer. We think it will keep your hot drinks piping hot for up to three hours. Then warm beyond that, up to six hours.
We think the design that has went into the Brew Flask sets it apart. From the 360 degree lid, the dappled exterior to help with moisture perspiration, a 90 degree twist lock cap to seal it properly and of course it's amazing green credentials completely set it apart from other coffee flasks in the market.
