Spotted Cow Grand Cru is a ramped-up version of Spotted Cow with malts that include Czech pilsner, pale, caramel and white wheat. An extra local touch is Wisconsin-grown barley from Buffalo County.
The “grand cru” title is common in wine as a way to note the high quality of a given vineyard and its terroir. Some breweries, too, like to use grand cru to designate a beer of highest quality, a special product, maybe even their best product.
