Mat Wadell

Head of Mixed Culture

In early 2019, we brought on established sour brewer Mat Waddell the former head brewer and co-owner of Wild Mind Artisan Ales, to take the reins as the head of mixed culture. Under Mat, we expect BlackStack’s new beers to push the boundaries of what is typically done with more concentrated and complex flavors.
