While I was purchasing some beers, including a bottle of Pierre Celis's Grottenbier, to drink with Easter dinner the shop owner asked if I intended to drink a toast to Pierre's life.

I had no idea he'd just passed away (9 April 2011). Pierre Celis was a true legend in the brewing world. Even if you don't know his name you have felt his influence.
Pierre Celis was born in Hoegaarden, Belgium where he spent much of his life. After the town's last brewery closed in the 1950s, Celis was singlehandedly responsible for reviving the witbier style in the '60s. By the time his brewery burned in 1985 its beer, Hoegaarden, was highly successful, attracting the attention of the large brewing companies. Celis was underinsured so had to partner with what soon became Interbrew (now InBev). The relationship soured, partly because of pressure to cheapen the brewing method, and Celis eventually ended up in Austin, Texas where he founded another brewery. Their beer, Celis White, was a beautiful interpretation of the witbier style. Again, financial issues forced him to partner with a megabrewery, this time Miller. And again, he left after feeling pressures to cut corners. Blue Moon, brewed by MillerCoors, illustrates what happens to a traditional style after a big brewer gets through with it.
Pierre Celis's respect for brewing traditions and local styles had great influence in this country. Many small brewers who were getting started in the late 1980s made pilgrimages to Austin to learn from the master. It would be difficult to find a beermaker from this period who didn't consider Celis a role model.
Of course the Pierre Celis story has local relevance with the acquisition of Goose Island by Anheuser-Busch InBev. The popularity of wild fermented and sour Belgian styles is exploding and the big boys want a piece of it. In recent years Goose Island has invested much time and effort into domesticating the microorganisms and improving production consistency for these beers—exactly the sort of preliminary work a huge brewer could make quick use of. Let's hope that all parties involved have learned something from the legacy of Pierre Celis.
