Shock horror! Found my first “plastic cork” yesterday, fitted to a bottle of Alentejano purchased purchased from Continente as it is referred to nowadays (what happened to Modelo?). From my (extensive!) experience this is a first on the island – back in the UK of course 9 out of 10 are plastic nowadays. I would guess that this is another nail in the coffin for the traditional Portuguese cork industry.
A quick “Google” revealed a fascinating web site http://www.cork.pt/cork-industry-in-portugal.html
Apparently Portugal accounts for 50% of the world’s total cork production and about 720,000 hectares of land are dedicated to the cultivation of cork oak trees on the mainland . I had no idea how many different kinds of cork stoppers there are – from “multi-piece” to “colmated”, “agglomerated” and “capsulated”
