I really doubt this info. Sake is popular in Japan and would be (or should be) categorized under wine, yet wine is at zero in southeast Asia. So either wine literally means "grape wine" or the data is fucked up.
Sidenote: Sake isnt actually popular on Japan, as it's seen as a "old man's drink". Saki sales locally have been dropping for decades. But the popularity of Saki internationally (thank you weebs!) gave it a major boost.
It could be categorized as "other" or "beer". "Wine" usually means grape, and when it isn't grape, it's usually fruit. Obviously, sake and other rice wines are called "rice wine", but if you are going to put them into a broader category, they probably fit better as a "beer". Non-distilled fermented grain
