Naparbier is a Spanish craft brewery founded in 2009, located in Noáin, in the autonomous community of Navarra. The brewery was established under remarkable circumstances: its founders had all lost their jobs and decided to channel their passion into building a craft beer venture from the ground up. From its very beginnings, Naparbier set out to produce high-quality beers using natural ingredients, positioning itself as one of the pioneering forces in Spain's evolving craft beer scene. Naparbier has built a reputation for brewing a diverse and adventurous portfolio, ranging from hop-forward styles to complex barrel-aged beers. Among their releases is the Gentleman Sour, an oak-aged Flanders Oud Bruin, which showcases their willingness to explore traditional European sour styles with a craft twist. Their use of natural ingredients and commitment to quality craftsmanship has made them a recognisable name not only in Spain but across the broader European craft beer community. Naparbier has been cited as one of the most important craft breweries in Europe, and their beers have gained international distribution, reaching markets as far as Romania and Belgium. The brewery has also participated in notable multi-brewery collaborations, including a nine-brewery project at De Struise Brouwers in Belgium, underscoring their standing within the global craft brewing network.
