Kingfisher Beer, in the northeast US (according to the below linked webpage), is a contract-brew from Olde Saratoga in upstate New York. http://www.oldesaratogabrew.com/brewlistKF.html
In a confusing ownership web, Olde Saratoga is owned by the Mendocino Brewing Co., which is in turned owned by Vijay Mallya, the head of the "UB Group" which claims to be one of the largest beverage companies in the world. http://www.mendobrew.com/company/history.html
It's relatively unusual for a beer to exist in a country as both an import AND a locally-brewed contract beer, if by "Northeast US" it means other parts of the US still get Indian-brewed Kingfisher- or possibly Mendocino-brewed Kingfisher? Any label readers know?
Contract-brews in the US have a mixed history- with the long-lived but now discontinued Miller's Lowenbrau the most notorious, of course. They currently started brewing Foster's domestically (after a stint as a Canadian-brewed "Australian" beer), even using the ridiculous dba "Oil Can Brewing Company". Granted, Foster's hardly has the reputation Lowenbrau had/has.
But the interesting trivia about Kingfisher is that, with the shared ownership of Kingfisher and Saratoga, it might be the first time a beer in the US exists in *both* a domestically brewed version and imported version from the same brewing company since Guinness' short-lived NYC area brewery in the late 40's-early 50's. http://jesskidden.googlepages.com/guinnessinamerica
