De Proef Brewery has a very different story than many other breweries in the world. Dirk Naudt and his wife Saskia Waerniers started De Proefbrouwerij in 1996. Dirk, a former professor of brewing science, started the brewery with the idea of being the ‘cleanest brewery in the world’. By all accounts he has succeeded in this endeavor. When you ferment a brettanomyces infused beer in a tank between a Czech pilsner and an imperial stout cleanliness needs to be at the top of your priorities. De Proef does all this and much more.
De Proef has specifically outfitted itself as a developer and producer of beers for third parties. With brewing systems ranging in size from about 6 barrels to 90 barrels, Dirk is able to offer his expertise to both large and small breweries. Many of the smaller and start-up breweries that come to Dirk either don’t have the money to produce the beer on their own, or are looking for an amazing or different product out of the gate. The larger breweries that approach De Proef may be looking to make a beer that is very different from their normal product lines, they may be contracting De Proef to help them meet demand on their normal products, or they may just be looking to collaborate on something special.
Each of the breweries that approach De Proef have a consultation with Dirk to figure out whether or not the beers and companies are a good fit for one another. Dirk frequently collaborates with the head brewers of these companies in creating the recipe, selecting raw materials, and adapting the technology of the brewery to meet the customer’s needs. Three brew houses, 58 fermenters, two bottling lines, two kegging lines, and a very committed team of beer geeks lends De Proefbrouwerij flexibility and integrity in everything they do.
This month we are featuring a beer of Dirk’s that hasn’t been brewed for another company. The K-O, or Knockout, is all De Proef. Brewed with pure malt, loads of hops, and tons of candi sugar, the Knockout tends to live up to its name. A very malty profile with honey, yeast, and caramel on the nose, K-O opens up with ripe apricot and a touch of vanilla. A large hop profile, mainly pine and citrus, help hide the high alcohol like a sucker punch. This one will sneak up on you if you let it. In the blue corner weighing in at 10% alcohol by volume, the commander from Flanders, the muscle out of Brussels, the Knockout!







In case you missed it, The Monk’s Kettle now offers a rare List of Vintage beers. We have unveiled a menu of beers that have been aging in our climate controlled beer cellar, most since our opening in December of 2007. This list will change over time and grow, as beers peak for consumption, and the seasons change. We now offer some of these bottles to you.
