Since 2002, I have spent 3 months of every year in Argentina, mostly in BsAs. During that time I have accumulated tasting notes, cost and other relative data on close to 400 Argentine wines. This is a hobby that dovetails with my professional life elsewhere. I have found a great number of acceptable local wines with good to excellent QPR's.
Champañas under $30ARS
Tamari Extra Brut Non-Vintage is usually available at Jumbo for under $25ARS. Yeasty, medium fine bubbles using the Charmant method; nicely balanced, but not bone dry; Produced by a subsidiary of Chilean Concha y Toro.
Nieto Senetiner Extra Brut Non-Vintage is widely available at prices hovering around the $30ARS range. This is a well balanced pinkish sparkler that is dry without a bitter finish; no cloying fruit.
Federico de Alvear Extra Brut Non-Vintage is similar to sparklers common to European countries other than France. Not as dry as a true Extra Brut, but perfectly acceptable for a pleasant afternoon luncheon. It has a good level of Charmant carbonation with a slight pear nuance. Quality varies somewhat from year to year, but you certainly cannot fault its value at 2010 prices hovering around $12ARS.
Red Wines under $20ARS
JS by Suter 2007 Malbec and 2007 Cabernet-Sauvignon varietals. Both offer a level of structure and sophistication the belie their $20ARS price tag. They are suitably oaked with soft tannins and a smooth finish that will be agreeable to both casual and serious wine drinkers. Available at Jumbo and Carrefour stores among others.
Pacheco Pareda Cabernet/Malbec 2008. Widely available for under $17ARS, this blend is well rounded with nicely integrated oak and soft tannins and a rich plum butter bouquet. It has a decent level of structure and depth given its price.
Familia Gascon Cabernet-Sauvignon 2006. If you can still find some bottles of this particular vintage, you'll find a yeasty, lightly oaked, smooth wine with a pleasant rich plum nuance. Widely available at prices hovering around or under the $20ARS level.
White Wines under $20ARS
Quara Torrontes 2008 is pressed from the varietal unique to Argentina. If you do not like perfumy or spicy wines in the Muscat or Gewurztraminer style, you will probably not like Torrentes. However, the Quara version is particularly well balanced and elegant without succumbing to the cloying perfume that can be evident in less refined samples. At the $16ARS or so price mark, it is well worth a try.
Ampakama Vignier 2008 offers a herbaceous pear bouquet with citrus notes It is well balanced and has a rich honey finish as it begins to warm. At $15ARS, it is an excellent value.
Estiba 1 Chardonnay 2008 is not the typical over oaked vanilla California version. It is dry, with nuances more common to Sauvignon-Blanc's. It is less fruity than most Chardonnays and as such is a very pleasant as an accompaniment to seafood or poultry. At around $14ARS, it has a very good QPR and is one of Bodega Esmerelda's best values.
