This new event emerged in 2015 when High Times canceled their Cannabis Cup* in Amsterdam at the last moment.
Local organizers in Amsterdam scrambled and quickly filled the void with their own event.
It follows the same basic format (music shows, cannabis competition, etc) but is done with an entirely new mindset.
Rather than go for big crowds and big money-grab, the local organizers decided on a more intimate gathering and low-key approach.
For example, a much smaller number of tickets (Judge's Passes) is made available.
Another characteristic is the lack of a vendor expo, which was the bane of High Times in the Dutch capital.
Most importantly The Amsterdam Cup has a much more local-flair about it without an American, mega-marketing feel to it.
These are two completely different events produced by two completely different organizers, who offer completely different experiences.
