CULTIVATING AUTHENTICITY. A wine promotional agency established in 1996, Le Maître de Chai represents more than 200 wine producers, and serves both the Quebec and Ontario markets. For over 20 years, Le Maitre de Chai has been one of the most respected wine agencies in Quebec. But as we’ve grown, we have never faltered from our founding principle: to transmit the passion of those who make wines that are both authentic and exceptional, and at all price levels.
