Cidre (cider) is not the most popular alcoholic beverage in France. Wine, beer and stronger liquors all outcompete that sweet fruity fizz.

Yet most French people agree that cider is the only right thing to drink with crêpes, the famous French pancakes.

But they don't agree on how to drink it.

Visit a crêperie in Brittany and they will serve cider from round bowls, une bolée, instead of glasses.

It's a longstanding tradition that few Bretons seem to question and just tacitly accept as the right way to go when serving cider. (Plus it's popular among tourists).

But in neighbouring Normandy cider is often served in a stemmed glass.

The sector is trying to push for more restaurants to opt for glasses instead of the bowl because, they say, it enhances the taste of the cider, which they hope could help their marketing and – ultimately – boost sales.

For now, producers struggle to get sales to go up outside big seasonal events such as la Chandeleur, the big crêpes day.
