Quintessentially Wine is available on any World Elite Mastercard. I am a member and have never received any exciting deals - you get the odd email offering you 10% off certain stock and the odd invite to tasting which come with disproportionately high price tags.
There are other World Elite travel deals that would come with the card - visit the Priceless London website, look under Travel and see which deals are marked as 'World Elite'. Again, nothing life changing.
