Obertrumer Original Bio Zwickl

Tap to rate

A full-bodied organic Märzen Zwickl made the way it used to be: naturally cloudy with a discreet haze, mild and rich in layered flavour nuances. The unfiltered yeast stays in the beer as a carrier of flavour, the organic barley comes from regional Austrian farmers, and a longer Slow Brewing maturation clarifies it gently. Bottled in the small bulbous Euro bottle with a 1970s Trumer label and less carbonation.

Tasting Notes

AI-generated sensory profile for Obertrumer Original Bio Zwickl

◎ Appearance

Golden amber with a natural, fine haze that catches light softly—the hallmark of an unfiltered Zwickl. The head is modest and persistent, with delicate lacing that clings to the glass. Carbonation is restrained, allowing the suspended yeast to remain visible and contribute to the beer's tactile presence.

◌ Aroma

The nose unfolds with warm, bready notes from the living yeast, complemented by subtle earthy undertones. Soft malt sweetness suggests caramel and light grain character, while a faint herbal whisper from the noble hops sits in the background without demanding attention. The overall impression is gentle and approachable, with no sharp edges.

◐ Taste

The palate is full and voluptuous, with rich malt complexity that evolves across the mid-palate—hints of toast and grain depth without astringency. Mild bitterness from Edelhopfen remains discreet at 25 IBU, allowing the organic barley's layered character to dominate. The finish is smooth and dry, with the unfiltered yeast adding a silky mouthfeel that lingers pleasantly.

The aftertaste is clean and gently drying, with a whisper of grain and yeast that gradually fades. No harsh edges or metallic notes—just a warm, satisfying conclusion that invites another sip.
