‘World’s first’ double-layered wine bottle launched

A German design company has launched what is claims is the “world’s first double-layer wine bottle” which keeps wine cold without the need to put it back in the cooler.

Called Cooleo, the bottle has already been adopted by German winery Wasem, which has ordered 6,000 bottles to house its Pinot Noir rosé and dry Riesling.

The double-walled bottle provides an insulating layer which helps to keep drinks cold, removing the need to put the bottle back in the fridge, the brand claims. It is made from hand-blown Borosilicate glass, which “has outstanding clarity and scratch-resistant durability”.

It is sealed with a glass Vinolok closure meaning that the bottle can be up-cycled and reused.

Kim Soohee, founder and CEO of the design company Our Wonderful World, which has launched the product, hopes that people will also customise the bottle using different designs, graphics, artwork and wines.

She said: “We are so excited to be launching this bottle that is beautiful to behold, shows the colour of the wine at its best and keeps it chilled in a natural, clean and sustainable way. We have spent the last three years selecting the suitable glass materials, developing the design and style that fits rosé and white wine and to engineer a double layer, insulating glass bottle that can be machine filled at high volume by wineries, or enjoyed by individual consumers”.

An experienced design professional who has lived and worked in London, Vienna and Seoul, Soohee became interested in wine and through visiting wineries believed there was a need for an insulated bottle.

Speaking in a Youtube video on the company’s website, she explained the design and production process.

“It has taken three years to develop. This started off with an idea, followed by intensive research, sourcing materials, finding out how we could produce the bottle and also make it stable enough to serve the function. We also then needed to find a manufacturer and they had a lot of challenges during the process.

“The bottle looks perfect as it is, but it’s very difficult to produce. It has four different parts and in every process, they need to make sure it’s perfect. They have to combine all the different parts and whenever there is an imperfection, they have to do it again.

“I hope people will find more use for the bottle instead of just buying it, drinking it and throwing it away. They can use it for wine, water or their favourite lemonade”.

Soohee enlisted the help of award-winning designer Oliver Conrad who drew up the initial sketches.

Conrad commented: “The Cooleo bottle is one of our most exciting product innovations. Our intention was to create a concept that combines traditional glassblowing with elegant, modern design. The result is a functional and beautiful product will bring a step change in wine marketing.”

“It is not just a form, it is an innovation. It helps people with something,” he added.

The bottle is available to pre-order via Cooleo’s website, starting from £22. It will be launching on Kickstarter on 22 July with a range of investment packages available.

Cooleo must be chilled in the fridge until it achieves the desired temperature. After that time, it says cooler for longer than a normal bottle, according to tests carried out by the brand.

Borosilicate, formed by the addition of boron oxide to soda-lime glass, is chemical and heat resident and is inert. While the stem at the bottom of the bottle mimics a wine glass, it is also necessary for the stability of the structure, according to the brand.
