KRUX Brouwwerf is a small craft brewery located on Cruquiusweg 83D in Amsterdam, situated in the Noord-Holland province of the Netherlands. The brewery is housed on the historic Cruquiuseiland, a former shipyard district in the eastern harbour area of Amsterdam. The taproom was previously known as Proeflokaal Bruut before being renamed and rebranded as KRUX Brouwwerf. The brewery is independently owned and operated by brewer Ward Venstra, who both brews and runs the establishment. KRUX Brouwwerf operates as a compact, hands-on brewery with the brewing space located directly behind the bar, giving visitors an intimate look at the craft brewing process. The brewery produces a range of beers and has collaborated with other Amsterdam-based breweries, including Homeland and Brouwerij De Prael, as part of local multi-brewery collaborations. Ward Venstra brews four beers as part of the core lineup, reflecting a focused approach to the portfolio. The taproom, or proeflokaal, offers guided brewery experiences that double as informal talks on the history of the site and the brewing process. KRUX is recognised among the top Amsterdam breweries on platforms such as Tripadvisor, drawing both locals and visitors to its characterful location on the former Cruquiuseiland shipyard grounds.
