Myths and facts


Some myths are hard to dispel... especially when they concern the quality, fragility or aging of the wine. Test your knowledge!

The heavier the bottle, the better the wine.

MYTH
The container is primarily used to protect the product and to facilitate the transport of the liquid. Glass is an inert material that adds nothing to the wine’s quality.

Lightweight glass bottles are more fragile and have an increased risk of breakage.

MYTH
Lightweight glass bottles meet all usage requirements for still wines. Thicker bottles remain preferable for sparkling products so they can maintain, as they need to contain the higher pressure (CO2) and not explode when being transported or opened. That said, even if sparkling wine bottles have to be thicker, they also exist in a lighter version!

Lightweight glass bottles are fine for everyday wines but not for ageable wines Thicker bottles provide better ageing conditions.

MYTH
Glass thickness has no impact on a wine’s ageability. It can matter in one situation: when bottles containing ageable wines are stacked on their sides for storage.
