Haig Blended Scotch & Homemade Wine
The big questions are: How hot does your attic get in the summer? If it gets blistering hot like ours (seriously, ours gets well over 100 degrees!) - it doesn't look too good for you. Whisky should be kept in 'cellar like' temperatures, so if it was freezing cold in the winter and steamy hot in the summer - YIKES! Not good.
Other question....was it stored upright? It's not supposed to be in contact with the cork.
Can't help you with the wine - there are so many variables - what kinds of grapes were used, how was it made, etc. Was it exposed to extreme temps and was it sealed properly???? Open it up and smell - go from there!
