As others have put down the Treana before, I actually was feeling quite vindicated when I read the article. I've always enjoyed it. I also agree that the Oregon Pinot was quite good, but haven't seen it as much as the Treana.
Now they just need to get more of the bottles on the plane and get the FAs to acknowledge they have it when they do. On a YYZ-LHR flight we asked twice if they had any wines not featured on the printed menu, with repeated confirmation that that was the full list, only to see the Treana wheeled out on the dinnner trolly 30 minutes later... still enjoyed it.
