Despite sharing the same grape varietal (or blend thereof), wines may be very different depending on the area they come from and/or the style of wine that the winemaker wish to create them with in the first place.

It you favor bigger, more structured and concentrated wines, I suggest you look into the following:

Clos de los Siete (Mendoza)
Pura Sangre (Mendoza)
San Pedro de Yacochuya (Salta)
Yacochuya Rolland (Salta)

For wines that are not as "big", with a more old-world infuence, here are a few names to consider:

Benegas Blend (Mendoza)
Escorihuela Gascon Pequeñas Producciones (Mendoza)
Enrique Foster (Mendoza)
Phillip Schell Reserve (Mendoza)
Noemia A Lisa (Patagonia)
Marcus Gran Reserva Merlot (Patagonia)

In the sparkling wine department, here are a few names (all wines from Mendoza):

Baron B Rose
Baron B Nature
Alma Negra Blanc de Blancs
Eternum 1999
Baron B Unique

Please feel free to PM me should you have any additional questions.

Hope this helps,
