Kasteelbrouwerij Ter Dolen is a Belgian brewery located in Houthalen-Helchteren, in the province of Limburg. It is situated on the grounds of a 16th-century castle estate with a history stretching back to the Middle Ages. The brewery opened its doors to the public in 1994, when the first beer — Ter Dolen Blond — was brewed, marking the beginning of a proud brewing tradition rooted in this historic setting. In 2024, the brewery celebrated its 30th anniversary with a special limited edition release. Ter Dolen specialises in abbey-style beers, drawing inspiration from the monastic brewing traditions long associated with Belgium. The portfolio includes classic Belgian styles such as a Blond, a Tripel, and specialty beers like the Ter Dolen Rouge — a beer brewed specifically to mark the brewery's 25th anniversary. The combination of a hypermodern brewing facility within a medieval castle domain gives Ter Dolen a distinctive character, blending heritage with contemporary craftsmanship. Beyond its core range, Ter Dolen has also ventured into more adventurous territory, including a Sour Red Ale brewed with cherry, coriander, and orange peel. The brewery is recognised as a regional pride of Limburg and is listed among the province's notable local producers. Visitors can explore both the scenic castle grounds and the modern brewery, making it a destination for beer lovers and history enthusiasts alike.
