Don't Get Drunk On Constellation Brands Stock. Constellation Brands (STZ) is an international producer and marketer of more than 100 brands of beer, wine, and liquor. The company’s well-known brands include Corona, Robert Mondavi, Modelo, and Svedka Vodka. Constellation has grown largely through acquisition, a strategy that has looked good on the surface, but is a sham when it comes to profits. Recent improvements in revenue and EPS serve as cover for a cash flow black hole.
