Itche: Just for you I pulled up my handy dandy bar ilan and looked it up.
Here are my results:
The following poskim speak on this halacha, and don’t say that any sort of alcohol is preferable to any other:
Mechaber
Rema
Mishna berura (and beur halacha)
Taz
Magen Avraham
Shaarei Teshuva
Chayei adom (explains it is because nes was with drinking wine, but doesn’t say that the only mitzva is davka grape wine as opposed to apple wine or barleywine or beer.)
Levush
Elya rabba (elya zuta says to eat and drink the first night also)
aruch hashulchan
I haven’t found anyone yet who insists it must be grape wine only.
