What Exactly is a Mustard Sommelier?

OLM chats with Maille mustard sommelier, Harry Lalousis

“Sommelier comes from the ancient Gaelic word for ‘someone who knows’ or ‘someone who has knowledge of,’” explains Harry Lalousis, Maille’s mustard sommelier. Although we usually associate the word with wine, Lalousis explains that the term can apply to a variety of areas of expertise—including mustard.

As it turns out, the mustard sommeliers of the world make up a very small group with an extensive history. The profession dates back as far as 1747, when Antoine Maille opened a mustard boutique in Paris with over 108 flavours.

“When he opened the boutique he knew that people would need to know about the mustard,” Lalousis says. Although mustard had been in Dijon since the 13th century, it hadn’t reached Paris in the same way, and customers needed someone to explain what they were tasting.

It was here that the mustard sommelier profession was born. People who ‘had the knowledge’ worked in Maille’s boutique and could discuss the mustard and suggest food pairings.

“Just like today we are faced with the challenge of trying to show people how to use mustard in a different way other than just on a steak or a hotdog. (Maille) faced the same challenge,” Lalousis says.

However, Lalousis adds that the last mention of a mustard sommelier in a Maille boutique was in 1876. The title didn’t reappear until he revived its history just last year.

“I was first approached by the company to start as a retailer and then very quickly I realized that I love this so much, I want to know as much as I can,” he says.

Lalousis opened the London boutique and then travelled to Dijon to learn as much as he could about the harvesting, flavours and history of Maille mustard—and he is still learning.

“It’s a journey that has not stopped to this day,” he says. “Every day you learn something different.”

Since then, Lalousis says interest in the career, the company and the condiment has blossomed.

Currently, there are three Maille mustard sommeliers in the world, including Lalousis as well as another in France and a third in the United States. In Canada, Maille recently opened pop-up shops in Mont-Tremblant and in Toronto at Pusateri’s Fine Foods. Lalousis says Ottawa will be added to that list in the future.

“It goes by demand. Everyone has been asking for it, so we just haven’t had time enough to open everywhere at once,” Lalousis explains. “I think the interest here that we have had is almost on the verge of ridiculous.”

Lalousis says it’s hard to pick his favourite Maille mustard. “It depends on my mood. I think the one that I really do enjoy more than the others is the honey and balsamic mustard. It’s a classic. It’s beautiful.”

You can use these mustards to enhance your everyday dish but there are also some really interesting and creative ways to use them, from mustard macarons to ice cream!

Lalousis says his love of mustard developed much like it does with his customers.

“I was pleasantly surprised by the availability of varieties,” he says. “And I think it was the shock that I got from how you can use it in your cooking that made me want to be a mustard sommelier.”

Now, he says, one of the best parts of his job is seeing that surprise on other people’s faces.

“I love converting people in food,” he says. “When I’m at the boutique or when I’m at the pop-up, I wait for that moment they put it in their mouth and the surprise that they get, that’s what I live for.”
