The label says its kosher — but not to one of the world’s biggest liquor producers.

The Absolut Co. is suing a Brooklyn Orthodox Jewish liquor distributor for selling a rabbi-approved knockoff of their famed non-kosher Kahlua coffee liqueur they say tries too hard to confuse consumers.

Lawyers for the Swedish vodka company claim that Happy Hearts Wine has been peddling the knockoff — named Kahfua — at Orthodox Jewish liquor stores, according to the Brooklyn federal lawsuit.

Except for the swapped ‘f’ for the ‘l’ in Kahlua, the labeling on the dueling liqueurs are nearly identical, and Absolut is demanding that the copycat products be pulled from shelves immediately.

“Defendant’s counterfeit Kahfua product is virtually identical to and substantially indistinguishable from the genuine Kahlua coffee liqueur product,” the suit states.

A man who answered the phone at Happy Wines confirmed that the Kahfua brand is in demand by pious Jews because Kahlua does not conform to their dietary restrictions. He would not comment on the lawsuit.

A Post reporter purchased a bottle of Kahfua at Liquors Galore in Midwood for $19.99 Tuesday and was lectured by a pair of Orthodox Jewish staffers after he asked if they also stocked Kahlua.

“Kahfua is much better,” one of them said. “The taste cannot compare.”

“Kahlua is a coffee liqueur,” his partner chimed in. “Kahfua is espresso. They’re totally different.”

The defensive duo explained that traditional Kahlua was not kosher and that Jewish consumers needed an religiously acceptable alternative.

The Liquors Galore employees even denied the clear similarities in labeling and logo designs, arguing that the fonts were totally different.

“You’re clearly not looking at it,” one of them insisted.

A lawyer for Absolut declined comment.
