I emailed Terrabianca to ask them about the changing of foil from black to red.
I inquired if it had anything to do with making the Wine Spectator Top 100.
Here is their reply by email:
Dear Campaccio friend
Thank you for appreciating the Campaccio 2007
We had decided to change to a red foil last july togheter with a small text change on the label to restil lightly the Campaccio outlook.
It has nothing to do with the ws top 100.
Hope to see you one day in Toscana.
