Thanks for the video, Francisco.
I've already read, a few months ago, the handwritten dissertation of Manuel Weinholtz - "A Cultura da Figueira no Algarve - Growing Figtrees in Algarve". Very interesting descriptions of fig cultivars and practices, particularly the chapter about caprification and the myths and misconceptions about that practice. Sometimes, it seems we haven't evolved much on that respect.
Regarding Cótio - being one of the most cultivated varieties for such a long time, we would expect several strains with different characteristics. To give it such a low mark, they probably didn't evaluate one of the best strains and, most likely, sampled a non pollinated crop.
