Unless you are very wealthy Scotch from years back becomes highly collectable and expensive . Thing is they don't really taste any better than current offerings as it doesn't age like wine due to the high alcohol content so unless you plan to invest and collect that's not the route to go .
Best to read some of the discussions on here or ask some questions about what you may like and I'm sure you'll get lots of great advice from members on here .
Scotch is an interesting and never ending journey with a new one beginning at the opening of one you have not tasted before.....enjoy !
BTW , my oldest son is a Lt. in the Army (CDN)
