It is reminiscent of the traditional wine bottle made of glass but a crystalline pattern gives it quite a different visual appeal. The Bordeaux bottle’s design marries the traditional shape with the indentation in the base to contemporary elements. The new design also features a concave base (punt), just like the traditional Bordeaux bottles. That shape has proven its worth ever since it was developed: When wine is stored, tannins and colourants polymerise over time, resulting in a sediment (or deposit) which can be detected in the liquid either as solid or turbid matter. The indentation in the bottle’s base produces a groove where such matter can settle, so it is not swirling around in the wine when it is poured. Prize-winning design Cornelia Braun was awarded the 2023 Prize of the Association of German Engineers (VDI) for the design she developed. What particularly impressed the jury was the technical and design-related solution she found in answer to the multifaceted challenges involved, not least the consummate combination of high-quality wine with a container material that may seem a bit unusual at first glance. www.krones.com
