Did you know that since 2010, the average weight of wine bottles sold at the SAQ has decreased thanks to concerted efforts with our suppliers?
And further weight reductions are in store as we continue promoting this solution for
the products on our shelves!
Why are we big on lightweight glass?
This issue deserves our attention because it’s one way of reducing the environmental footprint of the products we sell. And it does so through reduction at source. Here are the benefits:
- Uses less raw material, specifically less sand, which is a non-renewable resource.
- Reduces (by tons) the amount of residual materials to be managed.
- Lowers freight charges, which are based on weight.
- In addition, lighter bottles decrease the risk of injury for our employees.

In 2022 alone, the use of lightweight glass
resulted in a reduction of 6000 tons of GHG emissions.
That's the equivalent of about 6000 roadtrips between Montréal and Vancouver*.

How to recognize a lightweight glass bottle?
You can tell by the weight, of course. But there are other clues too: the bottles are usually flat-bottomed and sometimes have shorter necks and narrower shoulders.
An international agreement
to reduce the environmental impact of wine bottles
In 2025, the SAQ joined the Sustainable Wine Roundtable’s (SWR) Bottle Weight Accord to reaffirm its commitment to reducing the environmental footprint of the industry through lightweight glass and eco‑friendly alternative containers.
“It is with great enthusiasm that we take part in this accord because it allows us to continue exchanging and collaborating with the industry in achieving common goals to which we have been committed for several years,” said Marie-Hélène Lagacé, Vice-President, Public Affairs, Communications and Social Responsibility.
A little background…
In the fourth century, punts kept bottles standing
Have you ever wondered why some wine bottles have a dimple in their base? Called the “punt” or “kick-up,” the indentation is thought to have been invented by glassblowers in the fourth century to help bottles stand on their own without tipping over. Today, 17 centuries later, manufacturing techniques have eliminated the need for punts. Making a bottle with a dimple in their base requires more glass than is needed for a flat-bottomed bottle. Also, bottles with deep punts weigh more, adding to their environmental footprint.
Why aren’t all the SAQ’s bottles
already lightweight glass?
90% of targeted wines retailing for $30 or less at the SAQ already come in lightweight glass bottles. All told, they account for 40% of bottles sold. Did you know that since 2024-2025, sparkling wine bottles must also be lighter? And we're continuing the work for spirits bottles!
But let’s be honest: this is a long-term process. With some 6,026 suppliers in 77 countries, we have our work cut out for us. Because even though our partners want to modernize, they can’t until lightweight glass becomes available in their country!
