PORTO - Research by journalists Eelco van Wieringen (Buro Publieke Werken, Holland), Micael Pereira (Expresso Portugal) and Twan Kroon (researcher, Holland) shows that the age of port wines is often incorrect. They commissioned scientific research into the actual age of 10 and 20 year old Tawny ports. In more than half of the cases, the bottles appear to contain too young port.
