(Adds details from conference call, analyst and CFO's comment; updates shares) By Nivedita Balu Oct 4 (Reuters) - Constellation Brands Inc raised its full-year profit forecast and reported better-than-expected quarterly sales and profit on Thursday, as it benefited from strong demand for Corona beers during the summer, sending its shares up as much as 7 percent. The company launched the first major addition to the Corona franchise in nearly three decades earlier this year, the low-carb, low-calorie Corona Premier, aimed at seducing millennial consumers as it battles competition from craft beers. Corona Premier and Corona Familiar, a product launched for Hispanic markets, have both continued to exceed expectations, Constellation said. These additions, and its slightly more expensive brand Modelo, drove beer sales up about 11 percent to $1.53 billion in the second quarter.
