Green, bio-logical, or bio-illogical glasses?

Following up to the post launched from my collegue from “Azienda Agricola Berti” about the green glasses assigned this year in the “Gambero Rosso” guide:

Yesterday, with a lot of delay, I discovered that this year Gambero Rosso, with the usual three transparent glasses, also assigned “green glasses” . Obviously I won’t go into details about the value of the wines who got the prize, but I did take a look at the rules you need to respect to obtain them…

The rules are confused and not credible, vague and quite contradictory as well. For example, low sulfites… what does it mean? How about giving some reference? And also: Don’t buy the grapes from third parties. Does this mean that the third party grapes are always bad quality ones?
