Interesting, what do they mean by "rarities"?
Rarities can be defined as a variety of whisky bottles.
Yes, like Anzorchik777 said, it is about rare bottles that you can hardly find. WHYTOKEN GmbH defines this as a unique market opportunity, which are caused by special events. These include distill- eries such as Port Ellen, Brora and Karuizawa, which are now closed and no longer produce whisky.
