Hi, I have some bottles of various alcohol beverages from the 90s but I don’t know if I can drink them

Hi everyone, I’m 25 and I found some alcohol bottles in a cupboard in my kitchen that are from the late 90s. Nothing too fancy, most of them are various types of whiskey, but I have this bottle of Porto wine that seems interesting… Is it safe to drink? It’s sealed but it was not always conserved in a dry environment, at least for the last 10 years (my new house is kinda humid). I don’t drink lol, I just do it socially sometimes and I would like to share the bottle for free with friends (usually our group is about 13+ ppl) so I don’t wanna poison anyone 😂😂 Thanks everyone, I’m a total newbie when it comes to alcohol.

Also most likely it’s not like a super rare bottle, it was probably something cheap/entry level at the time, nothing fancy
