Lopez de Heredia, the venerable old Rioja produer, is, to most people, the foremost example of traditional Rioja. And, they're one of my absolute favorite producers.
Founded in 1877, and still in the hands of the same family, this is as special as traditional Rioja gets.
The Viña Bosconia 2003 isn't the current vintage anymore, as the 2004 has been released, but it isn't too far off current vintage. That's how long LdH ages their wines.
This has aged about 5 years in old oak barrels and another 4 years in bottle before release. That's about 9 years in the deep, dark, damp cellars of LdH. And keep in mind that this is only the reserva! The current releases of their gran reservas (Tondonia and Bosconia) are still in the mid 1990s!
There's some disagreement about the difference between LdH's Bosconia and Tondonia. To me, the difference is that Bosconia is more fruit-forward, rounder and more Burgundian in a sense.
