Product Description

We’ve had countless disappointing vacuum bottles. So in an attempt to find the very best, we transformed our kitchen into a lab and did some simple household testing. 

We preheated the bottles with boiling water for 10 minutes, then refilled them with fresh boiling water. We took measurements at random intervals and re-ran the test with the 3 best bottles. But even the best ones let the temperature drop to about 40ºC after 19 hours – the temperature that makes most people decide not to drink the coffee anymore.

The Shira bottle outperformed every bottle we had: after 48 hours, we still had a reasonably warm cup of coffee. Highly recommended!


Shira Vacuum Bottles keep beverages warm in the winter and cold in the summer. The highly durable bottle is made from double-walled 18/8 stainless steel with vacuum insulation and copper coating in between. The One-Piece Stopper prevents leaking. The large opening makes cleaning the bottle simple. The lid is lined with BPA-free plastic and can be used as a cup. With its powder-coated outer, the Shira looks absolutely stunning! The BPA-free Shira Vacuum Bottle is equipped with a unique getter to complete and maintain the vacuum over time.
