Opener Bier is a Dutch microbrewery based in Dongen, a small town in the province of North Brabant in the Netherlands. The brewery traces its origins to 2015, when founder Frank Wouters purchased a Speidl Braumeister homebrew system and began developing a range of beers. What started as a passion project grew into a fully-fledged microbrewery that has since established itself as a local craft beer producer in the Dongen area. The brewery is also listed among the broader portfolio of Royal Swinkels Family Brewers, the Dutch brewing group known for its diverse stable of beer brands. Opener Bier focuses on craft and specialty beers, with a hands-on approach typical of smaller microbreweries. The brewery engages closely with its local community, participating in regional events such as the Dongense Lentebiertocht, a springtime beer tour in Dongen where each location pairs a unique dish with a fitting Opener beer. This food-and-beer pairing philosophy reflects the brewery's dedication to craftsmanship and local hospitality. The brewery maintains an active presence on social media and takes part in initiatives such as the Week van het Nederlandse Bier, showcasing its beers alongside other Dutch craft producers. With its roots firmly planted in Dongen and a growing reputation in the regional craft beer scene, Opener Bier represents the spirit of small-batch, community-driven brewing in the Netherlands.
