Clueless teetotal seeking advice on dessert wine, mulled wine and gin!

[UserThenLotsOfNumbers]

Please let me start by saying I'm really ignorant when it comes to alcohol.

I've had a sort out at home and found the following, which were bought as gifts (from friends who forgot I don't drink ). My question is, are they still ok to drink? I don't drink myself but if they are ok I could give them to a friend.

Chocolate dessert wine - about 3 years old, never opened
Mulled wine - from last Christmas, never opened
Gin - from Christmas, has been opened (to try)

All kept in a cool, dark environment.

Thanks!

Gin and mulled wine fine.

Chocolate one will have a best before date. It may have turned. You would need to get someone to open it and check, my dad would drink it!! Or turn it into a cheesecake.

Thanks moobar! Sorry to be thick, but how long would mulled wine and gin last for - or do they never really expire?

I had another look at the dessert wine, no use by date on it, just says "use within a month of opening".

They will all be absolutely fine.
