“Coffee is not my cup of tea”

Someone’s “cup of tea” (what someone likes or prefers) has been an idiom since at least the 1920s. “Coffee is not my cup of tea” is a jocular one-line saying that has been printed on many gift items—especially cups.
 
Movie producer Samuel Goldwyn (1879-1974) is sometimes credited for the line (along with many other language “Goldwynisms”), but there’s no evidence that he ever said it.  “Coffee is simply not my cup of tea” was cited in print in 1959 and “Getting up at 6 to fix your coffee is not my cup of tea” was cited in print in 1965.
