Hi Alex,
I'm sure you are aware of the Tesco offer (half price, at £5.00 a bottle) on the 2002 Marqués de Caranó Gran Reserva (see above posted 14.05.10), but I think I ought to draw it to your and other's attention.
When I posted, I had not actually tried either reds, but thought them good enough (at the price) to recommend. I have now tried both and my recommendation stands.
Tonight had a couple of glasses of the Marqués de Caranó with a boeuf bourguignon with boiled new potatoes, carrots, sugar-snap peas, fine green beans, asparagus and broccoli.
Now that Tesco no longer have the 2005 Berberana on offer, the above is a very acceptable alternative. Fortunately I bought another dozen bottles before the offer ended.
Regards
