This is becoming very interesting!
First of all, Springwise has selected this event to be featured on its site for trend spotters and entrepreneurs everywhere.
Second, the little dinner alongside the tasting that Andrew and I were going to hold, is turning into a 5 course banquet of delicacies for a group of 5 or 6 "movers and shakers" in London's digital world. Identities are currently being protected to stop the groupies, other than mine, mobbing my front door :)
Lastly, I have found a few more sites that you might want to check out if you are thinking of joining in at all:
http://twittertastelive.com: set up by binendswine as the home of the events, presumably
Twitzu Event page: register your twitter ID here so we all know you will be taking part
1 Wine Dude's Yahoo Live! Broadcast: unlike my event, Joe Roberts will be broadcasting his dinner party and tasting live (assuming all this twittering activity does not crash the whole internet)!
