OPAT Bitter Kvasničák

Tap to rate

OPAT Bitter Kvasničák is an unfiltered pale výčepní, extra hopped for a more pronounced bitterness and aroma. Live yeast gives it a light haze and a full, authentic taste. It is brewed the traditional way from drinking water, barley malt and processed hops; kvasničák is the Czech word for a beer that keeps its live yeast.

◐ Taste

The palate opens with a crisp, malty foundation before pronounced hop bitterness takes hold in the mid-palate. The 25 IBUs are well-balanced and structured, delivering sustained rather than sharp bite. Bread-like malt flavors remain present throughout, while the live yeast adds a slightly tangy, full-bodied texture that feels authentic and unpolished.
