Today i came across a litre bottle of Singleton - 10 Years Old (Auchroisk) at a whisky shop. I knew that this was a discontinued bottle but wasn't sure if this will be a good investment. The price at the shop was very good though. I'm not intending to drink it myself but sell it for profit. With the profit i could buy a nice bottle i like. On whiskyexchange i saw that the price is £89.50
So in short, is this a good investment?
Thanks!
