Calcu Tiny Blocks Gran Reserva Cabernet Sauvignon 2020 (Chile) - Wine Review

Tonight's red wine review is a lovely, sustainable and vegan Cabernet Sauvignon (blend) that made its debut at the LCBO last month as part of the October 5th LCBO VINTAGES New Release Collection.

It is produced by Calcu Vineyards, a winery that began its life in 2003 as the unique project of the Hurtado family who have over a century's worth of winemaking experience making quality wines in the Colchagua Valley. The Hurtado family found a unique place in Marchigüe, in western Colchagua Valley, that is marked by granite stone hills which are the inspiration for the name of the winery - "CAL: Hill" and "CUrá: Stone".

The vineyards in Marchigüe have granite hills with clay seams, and are situated at altitude just 26 kilometres from the Pacific Ocean. The blend of differing orientations of the slopes makes the perfect blend which reflects the personality of the vineyard, and enables each variety to showcase the characteristic freshness, structure, verve, and depth in each Calcu wine.

With the core values of excellence, perseverance, honesty, and sustainability, Calcu is seeking to redefine Colchagua through the architecture of its vineyards. Excellence is reflected in the crafting of world-class wines by using high standards throughout each process and precision winemaking. With perseverance and determination, Calcu is continuously searching to improve their wine by taking action to achieve their proposed objectives. Honesty is the intention of their wines to naturally reflect their origin, and by scarcely intervening in the vineyards, the environment, and winery management. By adopting sustainable practices, Calcu is constantly implementing new measures and technologies to be more energy efficient, reducing waste and water consumption, while also becoming more environmentally-friendly. One of Calcu's sustainable initiatives was to design their vineyards in small blocks with short rows that minimize soil erosion, while the sloping rows are intended to reduce the risk of accidents for farmworkers.

Today, the passion for the pursuit of excellence is one of the fundamental pillars of the Hurtado family business and is reflected in each of their wines. This pursuit of excellence is implemented through precision viticulture and winemaking to accurately reflect the character of Calcu Vineyards in Marchigüe. Calcu Vineyards shares a winery with its sister company, Viña Maquis, in Palmilla in the Colchagua Valley, where they make and age their wines. This winery was built in 2002 under a sustainable concept and uses gravity technology to gently move the grapes, must, and wine throughout the winery in order to preserve the aromas and flavours of each of its wines. The winery is also innovative in that it is the only winery in Chile with a geothermal plant to generate energy, which is then used for wine production, thereby reducing its consumption of gas by 90%, and electricity by 40% per litre of wine produced.

Like the 2020 Calcu Tiny Blocks Gran Reserva Cabernet Franc, which I enjoyed earlier this year and included small amounts of other grape varieties to complete the blend, this Cabernet Sauvignon includes 7% Cabernet Franc, and 3% Petit Verdot. The grapes were grown at their vineyard in Marchigüe, 25 km from the Pacific Ocean, in the gentle hills of the coastal mountains where the soft breezes coming from the ocean moderate temperatures and allow the grapes to obtain freshness, aromatics, and excellent concentration. The vineyard is planted on granitic soils with important clay content that helps develop persistent aromas and increases concentration in the wine. The tiny blocks selected for this Cabernet Sauvignon have a high clay content, but are poor in organic matter, which helps to obtain lower yields, while also allowing the wines to have fantastic power, structure, and elegance.

To craft this red wine, the grapes were hand-picked, followed by hand-sorting of clusters and berries. It underwent alcoholic fermentation between 20-24°C, maceration for 18 days, and then malolactic fermentation, all in stainless steel tanks. The wine was aged for 12 months in French oak barrels.

The 2020 growing season experienced by Calcu in the Colchagua Valley was marked by a dry and warm climate, which challenged the team to be on high alert in order to identify the right moment of harvest for each block. The time of harvest is very important because this is what allows winemakers to maintain elegance and balance, characteristics which have embodied the wines of Calcu from this terroir. From a good vintage that produced high quality wines with excellent colour intensity and high concentration, which resulted in excellent complexity and very good ageing capability, let's see how this 2020 Cabernet Sauvignon from Chile is tasting tonight...

Tasting Note:

CALCU TINY BLOCKS GRAN RESERVA CABERNET SAUVIGNON 2020 - Sustainable, Vegan, Valle de Colchagua, Chile (#37867) (XD) - $17.95
This blend of 90% Cabernet Sauvignon, 7% Cabernet Franc, and 3% Petit Verdot has a whiff of reduction off the top, giving way to reveal fresh layers of ripe red and some black fruits, currant, cassis, and fine wood spice aromas of medium-high intensity, along with touches of dried herbs. On the dry, medium-full bodied palate it offers delicious red and some black fruit, currant, cassis, and dried herb flavour replays with smoky oak spice accents. Touch spicy on the mid-palate. Acids are fresh and juicy, while the ripe tannins are smooth and well-structured, with some grip on the back-palate. Minerally and savoury on the long, slightly chalky textured, and youthful finish. Should drink nicely to the end of the decade and is a highly recommended buy! Score: 90 pts
