Barrel Project 20.01 represents Brouwerij Kees's commitment to experimental barrel aging, a strong brown ale from Middelburg that spends months maturing in wooden casks. At 10% ABV, this beer embodies the brewery's philosophy of craftsmanship with boldness and character.

The barrel maturation adds layers of complexity beyond the base beer, drawing out dark fruit, woody notes and subtle vanilla undertones that define this carefully aged expression.
