It’s true, investors buy rare whiskeys as an investment.  The market for American Whiskey is newer than say the market for Scotch or Japanese whiskey, and as a result there’s opportunities for significant appreciation.  For instance buyers of the infamous 23 year old Pappy Van Winkle bourbon in 2010 have realized a 10 fold increase in their investment, assuming they haven’t drunk it.  Whisky Advocate magazine, which tracks the market, says overall price appreciation has been more modest, in the mid to high single digit numbers, a favorable comparison to the S&P 500 which over it’s lifetime has produced an average annual return of about 9.8%.  But if you dip your toes in the water on investing in spirits, be careful: counterfeits are a serious problem.
