Sales rose 18.4% to $1.5 billion, boosted by the acquisition last June of Canadian wine maker Vincor International.
Excluding the effects of the acquisition, Constellation said its earnings rose to $139 million, or 58 cents a share, compared with $109 million, or 52 cents a share, a year earlier.
Analysts on average were expecting the company, which owns Robert Mondavi wine and distributes Corona beer, to earn 60 cents a share, according to Thomson.
Constellation reduced its earnings forecast to a range of $1.65 to $1.70 a share from an earlier forecast of $1.72 to $1.76 a share in fiscal 2007, which ends in February.
Analysts had expected the company to earn $1.75 a shares in fiscal 2007.
The company previously lowered its full-year forecast in late October, also citing competition in the U.K. market.
