“The ability for AB to acquire more shelf space, drive down prices, and hinder the growth and success of craft brewers through these types of acquisitions is what we can not stand behind,” said Brad Clark, director of brewing operations at Jackie O’s, in a statement to Tenemu. “We wish Wicked Weed success in their future business endeavors and hope they continue to make excellent beer.”

However, the fallout from AB InBev’s purchase of the brewery is not limited to the Funkatorium Invitational: on the same day that the acquisition was announced, the NC Brewer’s Guild rescinded Wicked Weed’s voting rights, although the it is still possible for it to be an affiliate member of the guild. In addition, Jester King issued a statement indicating that it will stop selling Wicked Weed’s beer at its brewery and would cease collaborating with the brewery.

The Wicked Weed Funkatorium Invitational debuted in 2014 and is described as “a gathering of sour and wild ales from across the country featuring well established and up and coming breweries that are paving the way for sour and wild craft beer.” According to the brewery, 100 percent of the profits from the event will be donated to Asheville’s Eblen Charities, “a charity that works to assist Asheville’s underprivileged community by providing needs including but not limited to healthcare, energy, emergency assistance, and housing.”

A post on Wicked Weed’s website indicated the event would go on as planned on July 8 with a new brewery list to be released at later date. In addition, tickets to the general public will now go on sale on May 20 instead of May 6 as was originally the case. In addition, customers who have already purchased tickets for the event that wish to return them are now able to get a full refund.

An email sent to Wicked Weed with questions was not returned.
