These will keep a few years yet, especially the white Rioja (on the left). I first tried it in the '80s and thought it was horrid (like drinking solid oak, if such a thing were possible!) but a student of mine (he is also a wine merchant here in Madrid) changed my attitude towards it by serving me a glass from half a bottle that was left over from a wine-tasting he did 3 months earlier (thank you Andreas!), and the bottle had been open and out of the fridge that long. It was sensational!
These will be familiar to some of our (wealthier and/or aspirational) Iberian membership, I'm sure. They are not my day-to-day regular drinking! The middle one would retail today at well over 100€ a bottle (I just checked; the cheapest on line offer is currently 153€ for the '95 - I used to buy the '68 in 1981 in the UK for £4.50 or thereabouts!)
OK, in for a penny in for a pound, best buys for the others; Muga Prado Enea '06: 45,60€ and the white Tondonia '07; 72,00€. My average bottle spend these days: 4,00€.
