hopIQ found 10 beers with the same wheat and hazy character as Hachenburger Weizen. A wheat from the Westerwald — top-fermented, yeast-hazy, with a fresh-fruity nose. Cream-fine foam and a light amber-gold under the haze. At 12.5° Stammwürze the body is where a Hefeweizen should be, and the finish stays refreshing rather than sweet. Ranked by flavour match rather than popularity.
