Samuel, I have been to all the VIp tastings, I do not think Costas was in anyway deceiving you or the group. He had shared wines with us a few times already with clear warning about its status. To be honest, I do not get a chance to taste those wines anyway, so to me it is a win-win. It is always an experience and one that helps me grow my palate and knowledge.
I think we should slow down on the accusations. Sure, it is fine to speculate and state that you would be too afraid to buy the wine. Still remember two things:
1) Bad wine (if there is any) from Gotham, would be happily received back from Costas - of that I am sure!
2) If you do not want to buy the wine from Costas - many stores will price match.
Finally, if you all think the wine is going bad and therefore do not want to drink it - send them to me
