Aoltbeer

Tap to rate

Aoltbeer is the brewery's revival of Münstersch Alt, the historic sour beer of Münster, and its main product. Each release is a numbered blend from red wine and cognac barrels, fermented with the house culture of wild yeasts and lactic bacteria. The latest comes from a single barrique left undisturbed for four years: pronounced acidity carries notes of oak leaf and elderflower. Earlier blends showed orange, flint, green apple and light oxidation, and the line as a whole is fruity, dry and distinctly vinous.

Tasting Notes

AI-generated sensory profile for Aoltbeer

◎ Appearance

Pale gold to light amber, transparent with excellent clarity. The head is delicate but persistent, leaving fine lacing down the glass. Carbonation is gentle and refined, appropriate to the beer's vinous character.

◌ Aroma

The nose opens with bright acidity and floral notes—oak leaf and elderflower dominate, underpinned by subtle stone fruit. Four years in the barrel have layered in complexity: hints of wine wood, dried citrus peel, and a whisper of oxidative sherry-like development. The wild fermentation contributes a refined funkiness without harsh phenolics.

◐ Taste

Entry is bone-dry and intensely tart; acidity is the structural pillar here, bright and persistent on the palate. Mid-palate reveals green apple, flint minerality, and subtle dark berry notes, with the oak providing gentle tannin texture. The 6% ABV remains wholly transparent—no heat, only graceful wine-like body.

◑ Finish

The finish is long and sustained, driven by acidity rather than bitterness; the aftertaste moves toward citrus pith and dried stone fruit. A pleasant astringency lingers, inviting another sip.
