@Danny392 Officially - if you're selling alcohol to guests without the proper license, you might as well go ahead and offer them weed or cocaine or prostitutes while you're at it.
That said, if you happen to be in a very remote area with nowhere nearby to purchase wine or groceries, the possibility of an informal purchase might be worthwhile. You'd want to offer that strictly on a peer-to-peer basis, with no mention on your listing, and only after you've established some degree of trust with the guest.
If it turns out that you're actually close enough to shops that guests can supply themselves, this is a moot point. Guests would probably find it distasteful, as @Sarah977 says, if you made any hint of trying to sell them more stuff.
