==Zwanze Day 2011==
Zwanze Day 2011 marked the first major change in the Zwanze Day tradition. Starting with [[Cantillon_Zwanze_2011|Zwanze 2011]], a lambic with Pineau D'aunis grapes added, a simultaneous worldwide release party and tapping would happen on Saturday September 17, 2011. As a reaction to the commoditization of previous Zwanze beers, the brewery decided to not sell any bottles of Zwanze 2011 and instead release it at a worldwide party.
The press release for Zwanze 2011 stated: ''"In keeping with our approach to brewing and selling beer, as well as out of respect for the product and the attitude implied with the name Zwanze, we don't want these vintages to become marketing tools designed exclusively to make a few bucks. A case in point: Zwanze 2010 was bottled with numbered stickers, and after one bottle had been sold at the brewery for 6 euros another one ended up on eBay less than a week later with a price tag of 80 euros. Because of my dedication to my work as a brewer and out of respect for the product itself, it is very important to me for prices to stay reasonable. Unfortunately, there are those out there who couldn't care less about spontaneous fermentation beer but who do care a lot about making easy money. For this reason, it has been decided that not a single bottle of Zwanze 2011 will be sold by Cantillon Brewery"''
