Kid Rock doesn't know how to drink wine

Kid Rock knows how to splurge on a fine glass of wine, but has no clue how to drink it properly.

The singer ordered the pricy $28/glass Cakebread Cabernet while eating dinner at midtown's Lexington Brass late last week, but specifically asked his server to pour it into a highball glass -- better suited for a cocktail -- instead of a wine glass, a source dished.

"He was talking about wine a lot, commenting on the vintage of his wine, but then went with that glass instead of the traditional one," the source said.

We also hear he left a "hefty" tip.
