The WHISKYBASE is one of the mono-shops I love. They only sell whiskeys, but these whiskeys are from all over the world.
The two owners are on a mission and that is to share their love for whiskey with you. Even if you don’t drink whiskey yourself it’s worth paying them a visit as they love talking about what they have on offer and the shop is located at the interesting Zwaanshals quarter. Zwaanshals is one of the nicest shopping streets in the North with more specialised cool shops dedicated to for example Dutch design, 100% felt, wool for knitting, everything for cooking, perfect Hopper coffee and some nice restaurants.
Wishkybase has an online community where you can upload your own whiskey collection and share your thoughts.
I am not a whiskey drinker myself but I always go here to buy whiskey to give away as a present and each time I am here they suggest a different kind, all depending on the person I am buying it for :). They even sell small sample bottles for you to try.
