Brouwerij Cattus is a Dutch craft brewery founded by brewmaster Misaël van Leeuwen, rooted in the West Frisian region of the Netherlands. The brewery grew organically from what van Leeuwen himself describes as a hobby that got out of hand — spending years perfecting recipes before turning his passion into a fully-fledged brewing operation. The name and identity of Cattus revolve around a feline theme, which is reflected not only in the brewery's branding but also in the character of its beers. Cattus specialises in artisanally brewed craft beers that stand out for their distinctive flavour profiles and striking label designs. The brewery's bottle labels have received recognition for their unique and eye-catching artwork, earning a place among notable Dutch beer label designs. Their portfolio spans multiple styles, including beers listed under various craft categories available through Dutch specialty retailers such as Holland Craft Beer. Beyond its core range, Cattus has demonstrated a collaborative spirit by partnering with external projects, including brewing a custom beer called Koerspret for the Dutch technology and science podcast Met Nerds om Tafel. This willingness to engage with communities beyond traditional beer culture underlines the brewery's creative and accessible approach to craft brewing.
