Ottakringer Bio-Zwickl Dunkel

Tap to rate

Chocolate leads, with a hint of cocoa and a hint of coffee behind it and a malty backbone. Four carefully selected special malts give this dark Zwickl its aroma, and it is poured unfiltered, in the manner of a dark Zwickl. 4.9% ABV, 12.1° Plato and 30 IBU, brewed by Ottakringer in Vienna from water, barley malt, hops and yeast.

Tasting Notes

AI-generated sensory profile for Ottakringer Bio-Zwickl Dunkel

◎ Appearance

Deep mahogany brown with a warm copper undertone, held at SRM 16. The unfiltered nature produces visible cloudiness from yeast suspension, giving the beer a naturally hazy appearance. A tan head forms with moderate retention and fine lacing along the glass.

◌ Aroma

Chocolate dominates the nose with supporting notes of cocoa and subtle coffee. The four specialty malts contribute layered depth—toasted grain and a faint bready sweetness emerge beneath the chocolate character. The aroma remains clean and inviting, without sharp edges or harsh roast notes.

◐ Taste

Chocolate and malt form the core of the palate, arriving smooth and full on entry. Mid-palate shows soft coffee notes and a gentle roasted character that complements rather than dominates. Bitterness sits at 30 IBU—restrained and balanced, allowing the malt backbone to remain the focal point without becoming cloying.

◑ Finish

The finish is crisp and clean, with residual malt sweetness fading into a subtle dry aftertaste. The moderate carbonation supports a brief, pleasant fade without lingering heaviness.
