A long time, 5 years at least unopened or opened provided you keep it cool and out of the sun.
As long as it is kept cold, indefinitely.

howlong you want just store it in the fridge!
2 years
If you open the bottle, you need to keep it refrigerated and it will last for a month. If it is an unopened bottle it should last for about a year :)
It should last indefinitely if kept in a cool, dark place.
.Who is with you?
I'd start getting nervous after three years, depending on the brand.
I have a bottle of Cointreau that was first opened 16 years ago and it still tastes fine!
Chardonnay is good for about 7 years unopened.
Cheap wines are made and sold to be drunk immediately. They will not improve with age. You could keep a bottle of cheap red or white in a drinkable condition for about three years, but it won't be as good as the day you bought it.
My research showed that an unopened bottle of Pimm's would last for a year or two. Once it is opened, it starts to lose flavor after a week or so.
