There is no mention of the 'Vintner Court' anywhere in the canon. In fact, there's almost no mention of anything concerning Dorwinion at all, except for two namedrops in the Hobbit, and the location of the land, which does not appear in the canon proper but was confirmed by Tolkien to the illustrator Pauline Baynes.

Everything besides the name Dorwinion, its location, and the association with wine, are inventions by us to expand the world of Middle-earth for the Mod.

(A land named Dorwinion is also mentioned in the Lay of the Children of Húrin, an old poem from the earliest development of the Silmarillion Legendarium. Was that the same Dorwinion? Probably not, but such a question probably doesn't even make sense, given that 1) the poem dates from an early stage of the legendarium which has little in common with the published 'final' canon, and 2) Tolkien freely recycled many names and concepts from his legendarium into the Hobbit, which was originally a stand-alone tale, only retconned to belong to the same world as the Silmarillion Legendarium after he started writing LOTR.)
