Zwanze Day 2019 will be held on Sept. 28 and the custom creation being poured at events this year is very different than past incarnations.

As in years past, the annual event put on by Brasserie-Brouwerij Cantillon will be held in various locations around the globe on the same day, with each location pouring that year’s release brewed specifically for the festivities by the Brussels, Belgium-based brewery. Last year’s creation was 2018 Zwanze, a blend of lambic aged in three different types of wine barrels—Amarone, Chianti and Sangiovese—for two years; while 2017’s release was a two-year-old lambic brewed with Oolong (Wulong), a semi-fermented blue-green tea.

However, this year’s Zwanze beer is a “wholly unique brew” consisting of a smoked Lambic that incorporates a blend of classic pilsner malt and smoked malt that was brewed on March 1, 2016 and begged on Jan. 26, 2018.

“Rather than taking the beer to an extreme, we looked instead to find a balance between the acidic character of Lambic and the woodiness of the smoked malt,” reads a post on Cantillon’s Facebook page. “The result is a fine Gueuze with the classic notes of a Cantillon, complemented by an elegant smokiness in the nose and on the palate.”

According to Cantillon, the locations that the events are to be held at will be be announced “soon.”
