Bias Winery/Gruhlke's Microbrewery is situated on 64 acres overlooking the Missouri River bluffs and rich bottomland. The Winery offers a wide variety of spectacular views. Our 9 acre vineyard is visible from the tasting room, as well as from the indoor and outdoor seating areas. Weather permitting, our tram is available during most festivals for complimentary tours of the vineyard and estate. Come visit for an afternoon and picnic at one of the shaded picnic tables, or sit under the grape arbor or covered veranda right outside the Winery. During the winter, you can sit fireside in our large and accomodating Hearth Room.
