Brasserie Cantillon’s next Zwanze Day will take place in 2026 on Saturday, April 25, 2026. Once again, the event is planned for a full global scale.

What is Zwanze Day?

Zwanze day is a biannual event that Cantillon holds, in which they brew a small batch of an experimental beer and offer it for sale in a select group of pubs around the world.  This beer is usually a different style each time, and is something other than a traditional Cantillon lambic.  This allows the brewers to experiment and take part in the fun, semi-sarcastic humor of Brussels, the true meaning of the word zwanze.

Change to Biannual

In 2023, Cantillon decided to change the timing of frequency and timing of Zwanze Day in order to focus on the increased requirements to manage the production of their lambics during the autumn harvest period. Instead of hosting Zwanze Day every year at the end of September, the event will now alternate with Quintessence in April, with either Quintessence or Zwanze Day occurring each year.

Zwanze Beers

In 2026, Cantillon will do something new for Zwanze Day, with two different Zwanze beers being released on tap for the event. Both beers are vermouth blends in collaboration with craft vermouth producer Vermouth Sullivan from Besançon, France. There will be both a Kriek-Vermouth blend as well as a Lambic-Vermouth blend.

The Kriek-Vermouth Blend is Artémis La Rouge, and is a blend of Cantillon Kriek and a maceration of wormwood, marjoram, verbena, rosebuds, curry plant, and other herbs and roots.

The Lambic-Vermouth blend is Artémis La Blance, a blend of Cantillon two-year-old lambic and a maceration of gentian, rhubarb root, wormwood, coriander, juniper, sage, and many other herbs/.

I visited the Cantillon brewery in Brussels a number of times throughout 2013, including a visit in September for their Zwanze Day event both at the brewery and at the Moeder Lambic pub in Brussels. One of the best benefits of visiting the brewery in person is that you can often sample beers that are not available for retail sale and take-home consumption, but only for sampling on site. You also have the opportunity to tour the working brewing facilities during your visit, which is quite a treat as this is a true visage of old-time brewing traditional methods.

Cantillon has seen a large amount of growth recently, including the use of Brussels’ old abandoned bomb shelter for cellaring their beers for up to thirty years and an expansion near their current brewing facility that doubled their brewing capacity.  They also recently purchased a large new addition of barrels in which to age their lambics.  This should lead to increased production of their current line of offerings, and hopefully new offerings in the future?

Cantillon Zwanze 2014 – Cuvee Florian

For 2014, the Zwanze beer was called “Cuvée Florian“, and is a blend of Cantillon Oude Kriek, with 40% less fruit, and Iris Grand Cru, aged for three years in a 400-liter cask, with no secondary fermentation.  This beer was initially made as a one-off for Jean van Roy’s son’s 18th birthday, and has now been elevated to Zwanze 2014.

Zwanze 2015 was a spontaneously fermented stout called Wild Brussels Stout.  The beer was initially brewed in March, 2013 and was a candidate for Zwanze 2014, but was held back in favor of the Cuvee Florian.

Zwanze 2016 was a fruity lambic blend of raspberry and blueberry, with the tartness offset by some natural vanilla. This beer seems to have been a predecessor of Magic Lambic.

Zwanze 2017 is going to be an Oolong Tea – Two-year-old Lambic blend, made in honor of the 18th birthday of Jean van Roy’s youngest son, Sylvain.

Zwanze 2018 – The 2018 Zwanze beer, Manneken Pise, is a blend of lambics aged for two years in Amarone, Chianti, and Sangiovese barrels. The barrels impart a woody, wine-like character, with flavors of mango and citrus. The beer is dedicated to the Italian friends of Cantillon who help them to protect the traditional Lambic heritage.

Zwanze 2019 – The 2019 Zwanze beer is a departure from prior years, and will be a unique new beer, a smoked lambic, made with a blend of classic pilsner malts and smoked malts. The beer was brewed in March, 2016 and kegged in January 2018.

Zwanze 2020 – The Zwanze 2020 beer is called Brettrave, which is a play on betterave, the French word for beet. This beetroot Lambic’s color is an intense, almost flourescent red, with a fruity yet quite earthy aroma. The palate is complex, balancing the acidity of the Lambic with the earthy roundness of the beetroot.

For 2021, the Zwanze beer was Parasol, a special blend of lambic and citrus, mostly oranges. This Zwanze is a throwback to a recipe attempted 70 years earlier by Paul Cantillon, the brewer of Cantillon in the 1950’s, and the great grandfather of the current brewing family. The beer will have a thirst-quenching mix of lambic acidity with fresh fruitiness from the citrus, contrasting with the bitterness of the citrus zest.

In 2022, Cantillon Zwanze was a blend of two-year-old lambic and Congolese black pepper. The pepper is called poivre de Gorilles and came from Misao: La Maison des Poivres in Brussels. The pepper is grown wild in the Likouala Forest in the northeastern region of the Republic of the Congo, The forest is home to a number of the endangered Lowland gorillas. As such, a portion of the profits from the year’s Zwanze event were donated to Gorilla, an organization dedicated to protecting the great apes. Poivre de Gorilles is aromatic, but not too spicy. The spice blends nicely with the acidity of the lambic. It will pair well with meat or fish dishes.

The 2022 Zwanze proved so popular that it has now become a regular release from Cantillon known as Ashanti Lambic, with a little more focus on the lambic than the 2022 Zwanze release.

The 2024 Zwanze was a new type of flavor profile for Cantillon. The primary addition to the Zwanze blend was a type of sea lettuce such as is used for abalone farming in Brittany in France. There is a special batch of a few dozen bottles of Cantillon Gueuze lying submerged, aging in the sea near Finistère. The beers are aging in harmony with the local mollusks, who feed on different sorts of algae. This sea lettuce is the best of these algae and seaweeds to bend well with a Lambic, resulting in a perfect reflection of the concept of Zwanze. The Cantillon Zwanze 2024 was a departure from normal lambics, offering more salinity and iodine reminiscent of oysters.
