The Torrontes and Riesling grapes were grown on the Finca San Isidoro vineyards. These are located in the Cafayate Valley in the very heart of the Calchaqui Valley, distinguished for being the highest wine region in the world. The climate here is very dry, with just 150mm of rain in an average year and a huge thermal amplitude of around 20°C. The soils here are rocky, poor and sandy so the roots of the vines are forced to dig deep to find the vital nutrients and water they need, which in turn results in a huge concentration of flavour within the fruit.
The temperatures recorded during the winter were lower than average, with heavy snow in July. The lower temperatures continued into September and October, which slowed down bud break. 2018 was the driest of the last four vintages. Temperatures increased, well above average, from February to April. The increase in the temperature increased the sugar levels and polyphenolic maturity, resulting in high concentration of aromas and flavours in the grapes.
The grapes went through a double selection process, firstly in the vineyard and then again on the sorting table at the winery. The grapes underwent cold maceration for four days, followed by a slow fermentation using selected yeasts, at low temperatures to retain the varietal fruit character. 80% of the wine was aged in stainless steel tanks with 20% aged in French oak for 10 months.
85% Torrontes, 15% Riesling.
