The youngest I've tried from this brand name is the 1970 Don PX Convento Selección, the only one I tasted this time that fit into the classical canon, dense and serious with textbook aromas of carob beans, dark chocolate, tar and coffee and a relatively fresh palate with not so much alcohol and integrated sweetness considering it's supposed to have 510 grams of residual sugar.
