De Moersleutel Four Years Aperitif is a sour fruit ale from Dutch craft brewery Moersleutel in Alkmaar, brewed to mark their four-year milestone. At 7% ABV, this beer balances tartness with fruity character, true to its aperitif intent.

Founded by four brothers in 2016, Moersleutel has built a reputation for bold, fearless brewing across IPAs, stouts and experimental styles. This anniversary release reflects that spirit: a complex sour ale that combines sophistication with character.
