Port, which is named after the city. (

producing wine since the
late 1600s and produces around 200 million gallons each year, with a number of its wine producers employing the
old tradition of
crushing grapes with their bare feet. The tradition of wine making in Oporto is passed on down through generations from father to son. In addition to its wine fame, its other
chief industries
