German start-up Cooleo has launched the world’s first double-layered wine bottle in a bid to provide a modern and functional bottle with longer drinking pleasure.  The crisp, clean lines of crystal clear Borosilicate glass presents the wine’s true colour, and even though it’s light in weight, the double layer keeps wine refreshingly chilled. The bottle is handmade by artisan glassblowers, the bottle’s elegant, multi-layered curves not only provide winemakers with the perfect vessel for their wine, but it also gives artists a unique place to showcase their art on both the inner or outer layers of the bottle. The natural cooling double layer means you don’t need the fuss of ice buckets or repeat trips to the fridge.
