4 Islands Brewing was a craft brewery based in Rotterdam, in the Dutch province of Zuid-Holland. The brewery drew its inspiration from South Brazilian roots, blending influences from both South America and the Netherlands into its brewing identity. The name and concept reflected a connection to island culture and the founders' heritage, giving the brewery a distinct character within the Dutch craft beer scene. The brewery specialised in artisanal beers inspired by its South Brazilian background, positioning itself as a unique voice among the growing number of craft breweries in the Netherlands. While specific details about the full beer portfolio are limited, the brewery was known for bringing a cross-cultural perspective to its craft, combining traditional brewing techniques with flavours and inspirations rooted in South American culture. 4 Islands Brewing ceased operations in 2020, when it was announced that the brewery had closed its doors. Though its run was relatively short, it contributed to the vibrant and diverse craft beer landscape of Rotterdam and Zuid-Holland during its active years.
