Ocean Drift Cherry Sour is an alcohol-free cherry sour from JumpShip, brewed in Edinburgh. Part of the brand's Ocean Drift fruited sour series, it is made using lacto fermentation with whole cherries, taking its cue from Belgian Kriek. Lacto fermentation is driven by lactic acid bacteria, which creates the drink's sour character. As a seasonal release, it appears in limited runs rather than year-round.
