Cellar Key

Tap to rate

Caramel, chocolate, vanilla and molasses come together over a brown sugar sweetness, thick and boozy. Boulevard's master blenders drew on a barrel library of over 5000 casks for this Grand Cru blend, led by 44% Whiskey Barrel Stout in Kentucky bourbon barrels, plus an imperial rye ale, rum-barrel stouts and an eisbock. 13.8% ABV, a collection of the brewery's most exceptional vintages.

Tasting Notes

AI-generated sensory profile for Cellar Key

◎ Appearance

Deep mahogany brown with garnet highlights when held to light, revealing excellent clarity despite its full-bodied character. A thick, tan head forms with impressive retention and fine lacing that clings to the glass walls with each sip. The beer displays moderate carbonation appropriate to its Belgian strong ale heritage.

◌ Aroma

The nose opens with rich dark chocolate and toasted caramel, followed by vanilla bean and subtle oak from extensive barrel maturation. Underlying notes of molasses and brown sugar create a warm, inviting sweetness, while hints of bourbon whiskey and rye spice emerge on deeper inspection. The alcohol warmth is present but well-integrated, suggesting careful blending across the 5000-cask library.

◐ Taste

The palate enters with pronounced chocolate and caramel sweetness balanced by restrained bitterness from the 25 IBU foundation. Mid-palate showcases layers of vanilla, oak, and subtle smoky character from barrel aging, with the imperial rye ale and rum-barrel components adding complexity and gentle spice. The finish is thick and warming, with lingering brown sugar and a faint whiskey-barrel dryness that persists without harshness.

◑ Finish

A long, evolving finish that gradually shifts from sweet caramel and molasses toward drier oak and bourbon notes. The 13.8% ABV provides a comfortable warmth rather than harsh alcohol bite, and the aftertaste remains pleasant and contemplative for several minutes.

Serve at 12–16°C

Warmer than most — 12–14°C. The fruity esters, spice and warming alcohol need room to breathe.

Goblet

The wide mouth and heavy base promote head formation and channel rich aromatics toward the nose. Traditional for Belgian strong ales.
