Our Philosophy

Because we are convinced that high quality wine begins in the vineyard, we tend to the needs of every vine in the vineyard to ensure they deliver the best grapes, the best varietal expression, and the true identity of the Cachapoal Valley.

We believe in managing natural resources sustainably. We are grateful for the land and the bounty it provides us and practice viticulture with respect for the environment and the minimal use of agrochemicals.

Mindful of climate change and its impact on water resources, we monitor irrigation requirements regularly each season using our studies of soil conductivity and vineyard development to minimize water use.

Our viticulturists work side-by-side with our winemakers in the vineyards to discover the potential of each block, tasting the grapes, and determining the precise moment to harvest. Together we analyze the vineyard practices and activities to obtain the best from our lands and its fruit.

Because our own vineyards supply all of our needs, we can guarantee the quality and consistency of our work in the vineyard over time.

Cachapoal Valley

Our vineyards are located in Peumo, Cachapoal Valley, recognized as one of Chile’s traditional winegrowing zones, and date to 1824. Peumo is located between the 33rd and 34th parallels latitude south, 140 kilometers south of the Chilean capital of Santiago, and just 65 km (42 miles) from the Pacific coast.

Climate

The valley has a Mediterranean climate that is ideal for growing high quality Vitis vinifera (wine) grapes. The Coastal Range protects the vineyards by reducing the effects of the cold and moisture-laden winds from the Pacific Ocean to a level that allows the fruit to ripen effectively.

The valley has a very good weather during the growing season with no rainfall until May, which makes it the ideal place to grow the very late-ripening Carmenere.

The rainy winter (600 mm annually on average) is followed by a sunny spring with cooling breezes from the south. Summer brings a high average daytime-night time temperature oscillation of 20°C (68°F) with cold, relatively dry nights and days with high solar exposure, which helps keep pests to a minimum while promoting color and freshness in the wine. The autumn months are cool.

Soils

The valley has alluvial soils on the strip beside the Cachapoal River where our Riberas del Río Vineyard is located.

Our Viña Cerro Vineyards—where our best and most award-winning Carmenere is planted—are close to the mountains and have colluvial soils of granitic origin with a sandy-clay-loam texture and are very deep (2 m) with very good drainage and little stone content in the soil profile.

The soils in our Cornellana Vineyard are predominately of granitic origin and offer exception conditions for growing Cabernet Franc, Carmenere, and Syrah.

Our Palmería Vineyard is in the lower part of the property and has sandy-loam soils with good permeability as well as granitic soils in the foothills that produce very good expression in Cabernet Franc and Syrah.

We have Carmenere planted on the deep, porous, well-drained, stoneless clay-loam soil in the lower part of our Idahue Vineyard. We also have Petit Verdot there near the hillsides, where the soil becomes granitic with an abundance of stones.

The valley offers an almost limitless array of soils for the different varieties we grow and results in well-balanced, productive vines and grapes with intense aromas and flavors.

Wines from Cachapoal

Cachapoal is renowned for having one of Chile’s longest and most consistent ripening seasons, which allows us to obtain the exact level of ripeness required while preserving enough acidity to ensure the freshness of the fruit. This leads to excellent varietal character with round tannins, very good flavors, and balanced acidity.

Discovering Our Terroir

Viña La Rosa began in 1824 when the Ossa family acted on their dream of owning a winery and bought their first vineyards in the Peumo zone of the Cachapoal Valley. Today, 190 years and six generations later, the family remains convinced of the valley’s potential and continues to make its wines entirely from the best grapes the arrea has to offer.

Where is the best Carmenere?

As part of the ongoing goal of producing the best wines and convinced that quality is created in the vineyard, in 2011 we began a research project with Pedro Parra, an expert Chilean terroir consultant and close friend of the family who is dedicated to understanding the relationship between the grape variety, the soil, and the climate by mapping and describing the soils by means of multiple test pits.

Firm in our belief that Peumo produces some of Chile’s finest Carmeneres, we set out with Pedro to determine the best sectors of our Viña Cerro Vineyard for producing an exceptional wine. We studied the property comprehensively using electrical conductivity, aerial vigor images, and test pit analysis to divide the blocks into sub-blocks and select the best for this emblematic variety.

Our La Rosa Carmenère is the product of that project.

Eugenio Maffei, Head Viticulturist

Eugenio Maffei was born in Santiago in 1964 and enrolled at the Universidad Católica de Chile, where he earned his degree in agriculture with a specialization in fruiticulture and enology in 1989.

Eugenio officially became a winemaker in 1990 and obtained the award for best vitivinicultural thesis that year.

He began his career as viticulturist and winemaker at Viña Errázuriz Panquehue in the Aconcagua Valley, and then exclusively as a viticulturist at Viña Tarapacá ex Zavala, in Isla de Maipo. He later spent 11 years at Viñedos y Bodegas Córpora as the agricultural manager of vineyards from the Aconcagua Valley to the Biobío, and for the past six years has been agricultural manager at Viña La Rosa.

Eugenio’s hobbies include mountain biking, hiking, and tennis.

Jorge Espinoza, Vineyard Manager

Jorge Espinoza was born on February 5, 1983 in Peumo and grew up in Rapel Lake, always linked to the field by family tradition. He studied at the Agricultural School Las Garzas and later Agricultural Engineering at the University of Chile, specializing in fruit growing.

He began his career as a winegrower at Viña Concha y Toro in the valleys of Marchigüe and Cachapoal; and later he worked in Viña Casas del Bosque in the Casablanca Valley. Jorge joined Viña La Rosa team in December 2017, where he is the Vineyard Manager

His hobbies are football, enduro, mechanics and wood sculpture.
