Glass bottles are harder to find and much more expensive than they used to be. A wine maker buying glass bottles today could easily have to pay 30% more than they did last year.
The wine sector accounts for something like 45% of the market for glass bottles, which until recently was on a rapid rise – currently over 5 million tonnes, compared with 4 million tonnes in 2016, valued at over 2.4 billion euros. Sparkling wine producers probably paid much more for their bottles last year than they did in 2020.
A key part of the SIPA innovation is the bottle neck, which looks just like the glass version, meaning that it accepts the classical mushroom-shaped cork with its metal cage. The base also looks the same as the original. The design provides a top-load resistance of 3500N.
