My little tasting group ventured into these two varietals up on the suggestion of an attendee at our syrah tasting last month.  Not the easiest tasting to shop for, as many American wineries produce some nice tempranillo, but it's usually only sold at the winery.  Also, trying to ensure any wines from Spain I chose were predominantly tempranillo composed. 

I found one single vineyard carménère  at Total Wine and had another recommended by a wine shop owner which would satisfy the "reserve" portion.  Then I was between the Lapostolle Cuvée Alexandre and the Montes Purple Angel for the "top tier" choice.  The tempranillo wines were a bit easier with almost too many options. 

Our roster then became comprised of

Carménère

Anakena Single Vineyard (Plot: Malva) from Peumo, Chile 2009

Casa Silva Carménère Reserva from Colchagua Valley, Chile 2009

Purple Angel by Montes form Colchagua Valley, Chile 2008

Tempranillo

Burgo Viejo Rioja Crianza 2005

Volver Single Vineyard 2008

Condado de Oriza Crianza Ribera del Duero 2006

Montecillo Aniversario 130 Gran Reserva Edicion Limitada Rioja 1994

Bodegas Muga Prado Enea Gran Reserva Rioja 2001

Some surprises for sure!  We used the 100-point rating system and the average scores were

1. 88.6

2. 84

3. 83.8

4. 89.3

5. 90.3

6. 84.9

7. 88.4

8. 92

One of our guests also brought two lovely bottles to share. 

Paul Hobbs Napa Valley Cabernet Sauvignon 1998

Turley Zinfandel Pesenti VY (Paso Robles) 2000

Delicious!  Personally, my top wines were (scoring over 90) the Volver, Montecillo and Muga.  Both bonus wines as well.  All in all a fun night.  I'd see if you can find any of them locally and share your thoughts on them as well!
