hi, after a recent attic clearance we stumbled upon an unopened bottle of haig blended whisky, it seems to be approx. 30 years old.

1. is it worth anything ?
2. to anybody ?
3. is it drinkable ?
4. should it be decantered ( as per wine ) " to clean" ?

all help greatly appreciated. thanks.

p.s. also have home-made wine from 1950's ,
does anyone know the drinkability of this also ?
