hopIQ take
3 Fonteinen Oude Gueuze if you want pure, laser-focused sourness and complexity, Boon Oude Geuze if you want slightly more body and a rounder finish.
Both are lambic blends aged in wood, but 3 Fonteinen leans into that austere, funky precision—it's like biting into a green apple that's been thinking about it for years. Boon softens the edges just enough that the alcohol (7% vs 6.3%) becomes noticeable as warmth, not just fuel.

Tasting notes
3 Fonteinen Oude Gueuze
3 Fonteinen hits you with immediate tartness and a prickle of wild yeast funk—it's dry without being austere, almost mineral in the finish. The sourness doesn't scream; it whispers aggressively. There's a faint orchard note underneath, like stone fruit that's been left in the sun too long. It's the kind of beer that makes you sit up straighter.
Boon Oude Geuze
Boon Oude Geuze feels rounder on your palate, less knife-edge than 3 Fonteinen. The sourness is there but it's cushioned by a touch more residual sweetness and a slightly fuller mouthfeel. You get that same funky, barnyard complexity, but with a softer landing. The extra point of alcohol gives it a gentle warmth that lingers.
