Myth or reality: Are wines from heavier bottles better?

class=”sc-29f61514-0 dXbCZE”>

You’ve probably noticed that some wine bottles, whether full or empty, are heavier than others. They are usually slightly larger than normal or have darker glass than other bottles.

Heavy bottles make a positive impression on many people. “Wow, that’s a heavy bottle!” This is the most common reaction if a person is given such a bottle. It is automatically assumed that wine in a heavy bottle must be particularly good. But is this really true?

Partly just a marketing tactic

The positive thing that can be said about a heavy wine bottle is that it has slightly increased resistance to breakage. Sparkling wines also benefit from slightly heavier and more durable glass: The glass walls of sparkling wine bottles must have a certain thickness to withstand the pressure of up to six bars prevailing in the bottle.

However, the weight of the glass bottle has no connection with the quality of the wine. Even the bottles of the world’s best and rarest wines are no heavier than usual. Heavy bottles are only intended to create the impression of superior quality, and this often succeeds.

But heavy wine bottles have a very significant drawback: Their ecological footprint is larger than standard bottles. More weight has to be moved per liter of wine, leading to more emissions. And this has a negative impact on the environment.
