Boon Oude Geuze Mariage Parfait

Tasting Notes
The aroma opens with sharp acidity, wet hay, lemon rind, and a barnyard funk from wild Brettanomyces fermentation. On the palate, expect a complex interplay of tart green apple, white wine vinegar, and earthy, musty oak — the blending of aged lambics gives it more depth and body than a standard gueuze. The carbonation is lively, which drives the acidity forward on the mid-palate. The finish is long, dry, and mouth-puckering, with lingering citrus and leather notes.
About the Brewery
Boon is based in Lembeek, in the Pajottenland region southwest of Brussels — the heartland of spontaneous lambic fermentation. Frank Boon founded the brewery in 1975 after rescuing the historic Mariage Parfait blend from obscurity, and he has long been considered one of the most technically rigorous and preservation-minded lambic producers in Belgium. The brewery is credited with helping revive serious interest in traditional gueuze during a period when the style was commercially endangered, and its blends are benchmarks for the category.
Food Pairings
Aged hard cheeses like Comté or Gruyère work well because their nutty, crystalline character stands up to the beer's acidity without being overwhelmed. Oysters are a classic match, the brine and minerality of the shellfish mirroring the beer's funky, citrus-edged tartness. Charcuterie — particularly cured pork or pâté — benefits from the acidity cutting through fat. A sharp lemon tart or citrus sorbet also pairs effectively, leaning into the sour notes rather than fighting them.
Style Guide
Gueuze is a blended, bottle-conditioned lambic beer originating in the Brussels and Pajottenland region of Belgium. It is made by blending young (one-year) and aged (two- to three-year) spontaneously fermented lambics, then bottle-conditioning the blend to produce natural carbonation. The result is characteristically tart to sour, dry, funky from wild yeast and bacteria, and notably more complex and carbonated than a still, unblended lambic. At 8%, this example sits on the higher end of the style's typical ABV range, giving it extra body and aging potential compared to most commercial gueuzes.
