family of grapes, or wine made from them, 1833, from French. There seems to be no general agreement on the etymology; the word seems not very old in French and is from the Médoc dialect. Supposedly the best of them, cabernet sauvignon is attested in English from 1846.
kind of red-skinned eating apples, 1874, named for John McIntosh (b. 1777), Ontario farmer who found them in 1796 while clearing woodland on his farm and began to cultivate them. The surname is Gaelic Mac an toisich "son of the chieftain."
