Tartopia from Eleven Brewery in Utrecht is a fruited sour ale at 6.6% ABV. This beer emerged from a creative brewing partnership: a single base recipe of 2000 litres was developed into five distinct fruited variants in collaboration with Brouwerij Brouwersnös in Groenlo. The result is a refreshing and fruity expression that showcases the collaborative vision of both breweries.

Tartopia represents Eleven's range of experimental styles—from brett beers to barrel-aged stouts. The beer balances tartness with fruity character, appealing to those seeking crisp, layered flavours.
