of the grapes for the Argentine sparkling wine industry are sourced from this area. Located more than south of Mendoza, the vineyards of Bodega Weinert are noted as the southernmost planted vineyards in the Americas. The most significant vineyards are located in the Rio Negro Valley, where some of the most prominent Pinot Noir red wines in Argentina are made, and in the upper Neuquen Valley, especially around the town of San Patricio del Chanar. Additionally, there are promising vineyards located in the La Pampa Province near the Colorado river, near the city of 25 de Mayo. These regions have shorter summers with longer daylight hours, and significantly colder winters than the main wine areas further north. Besides Pinot Noir, the area is known for producing good Merlot wines as well as white wines (mostly Chardonnay and Sauvignon Blanc). Recently, however, the area has gained traction because of its promising Cabernet Franc red wines, which have added to the diversity of Argentine wine with their hint of red fruit, elegant tannins and peppery taste. . Further south, the Province of Chubut is a mostly uncharted wine frontier. Traditionally considered too cold for plantings, there are micro-climates (e.g. the irrigated Chubut Valley area near the Atlantic coast, the Trevelin Valley where Pacific winds moderate the climate, and some steppe regions) which are promising for winemaking. Production started in the late 2000s, with a new Wine Route established in 2017. The main plantings have been, so far, Pinot Noir, Chardonnay, Sauvignon Blanc, Gewürztraminer, Merlot, Riesling and Pinot Gris. New developments Argentine winemakers have long held the belief that vines required hot and arid climates with large temperature variations to produce quality wines. This 'winning formula' led to a concentration of wineries in Mendoza, San Juan and La Rioja provinces in the west, as well as higher-altitude vineyards in Salta. More recently, there has been a shift towards slightly cooler and equally arid climates further south, in Neuquen and Rio Negro. Wineries there still benefit from windy and arid conditions, but with cooler temperatures and a shorter growing season. However, in the last decade, the potential for 'non-traditional' (or re-discovered) regions has become apparent, concentrated in several areas: (1) the Atlantic coast from Mar del Plata (Buenos Aires) south and including the hills in Southern Buenos Aires, and (2) the mountains in Cordoba Province, which had been significant growers in colonial times, but
