De Struise Brouwers is a microbrewery located in Oostvleteren, Belgium.

Origin
Owners of a nearby ostrich-raising farm in Lo-Reninge with accommodations for vacationers, Urbain Coutteau and Philippe Driessens developed an interest in making distinctive regional beers to serve to their guests. In 2001 they began doing so with help from local wine maker Carlo Grootaert, and this project eventually developed into its own independent commercial concern.

Upon its inception in 2003, Struise produced beers at the Caulier brewery in northern Hainaut. Since 2006, they have been made at the Deca brewing facility in Woesten-Vleteren in West Flanders until 2014, after beers were brewed at their own brewhouse. The firm has reported that their own microbrewery and tasting room in Het Oud Schooltje (a renovated school building) located in Oostvleteren, is open and operational.

The company takes its name from the historic Flemish word for ostrich, which also is a contemporary slang term meaning "tough". They render the name into English as "The Sturdy Brewers", and many of their labels feature ostriches, a trait they share with Dutch brewery Brouwerij 't IJ.

Following industry trends made popular by American craft brewers, the brewery has recently ventured into stronger, more flavorful beers and also barrel-aging.

They have also collaborated with other European artisan beer scene such as Denmark's Mikkeller, Estonia's Põhjala, fellow Belgians Picobrouwerij Alvinne and Brouwerij De Molen of the Netherlands, as well as American brewers. While their Black Albert was originally conceived in concert with United States-based Ebenezer's Pub, a joint effort to create a "Pannepot Cafe" in Brunswick, Maine was abandoned in May 2009.

Awards and recognition
Craft beer fan rating website Ratebeer selected beers from DSB for 9 of their Top 100 Best Beers of Belgium in 2009. Struise was edged out for the #1 slot only by the venerable Trappist brewers of Westvleteren.

In 2008, RateBeer declared Struise to be the best brewers in the world per their annual members' poll. This was met with mixed opinions in the world of beer enthusiasts. Many of those critical of the award cited the recent founding of the company as well as the fact that DSB did not own a brewing facility at the time.

DSB also received 7 separate awards from Ratebeer in 2007, including accolades for the Aardmonnik and Pannepot.

The "Black Damnation" project
This project was conceived by the brewmaster at Struise. Their dark Russian imperial stout beer Black Albert serves as the base for a number of experimental brews that are to be released over a period of two years (2010-2012). As of June 2011, the following six brews have been released to the public:

Black Damnation (13.0% ABV): a bottled blend of the Black Albert with the Hel & Verdoemenis (Hell and Damnation) of Brouwerij De Molen.
Black Damnation II: Mocha Bomb (12.0% ABV): a blend of 50% Black Albert matured on coffee beans, 25% of the Dutch-brewed Hel & Verdoemenis matured in JD barrels for 6 months, and 25% Cuvée Delphine.
Black Damnation III: Black Mes (13.0% ABV): a version of Black Albert aged for 3 months in whisky barrels.
Black Damnation IV: Coffee Club (13.0% ABV): Black Albert, matured for 6 months on very old rum barrels.
Black Damnation V: Double Black (26.0% ABV): aged Black Albert (Cuvée Delphine) of which the contents have been concentrated through the Eisbock process.
Black Damnation XI: Special Kay (22.0% ABV): a mix of Black Albert and Kate the Great (Russian imperial stouts) aged on Noval Port barrels for 10 months, then put through the Eisbock process.

These brews have been completed, but are yet to be commercially released and have only been available for tasting at the brewery or at various beer festivals or other occasions:
Black Damnation VI: Messy (39.0% ABV): Black Mes put through the Eisbock process twice, ending up with 39% ABV. Brewed in honor of the wedding celebration of the man that inspired the original brew.
Black Damnation VII: Single Black (2.0% ABV): with only 2% ABV, this very light stout beer is called a BOB stout by Struise, meaning it can also be enjoyed (in moderation) by designated drivers.
Black Damnation VIII: S.H.I.T. (12.0% ABV): a blend of Black Albert and Shark Pants. S.H.I.T. stands for Super High Intensive Taste. This blend of a Russian imperial stout and an IPA results in a black IPA.
Black Damnation IX. Beggars' Art (18.1% ABV): Black Damnation aged on Ardbeg cask.
Black Damnation X: Double Wood (15.0% ABV): after adding fresh yeast during aging, it ages on Balvenie sherry casks.
