A golden, cloudy Kellerbier with live yeast, light spice, a light fruitiness and a bitter finish. It is bottled straight from the maturation tank, unfiltered and unpasteurised, and the amount of yeast varies slightly from bottle to bottle.

◐ Taste

Entry is crisp and clean, with a light malty foundation and a faint bread-like note that grounds the palate. Mid-palate develops the noble-hop bitterness smoothly, complemented by that delicate fruitiness and spice. The finish carries a measured bitter snap that persists without harshness, leaving a refreshing, dry impression.

◑ Finish

The aftertaste is dry and lingering, with a noble-hop bitterness that fades gradually and pleasantly. A subtle yeasty complexity on the back palate adds depth without overwhelming the overall sensation of lightness and refreshment.
