Just short of perfection in 2020, but this is still a world class wine from the brilliant Sebastián Zuccardi, sourced from a 0.74-hectare parcel on gravel and limestone soils within the Piedra Infinita estate. Scented, ethereal and energetic, this is a detailed, complex,unwooded Malbec with blood orange and blackberry flavours and some underlying grip andbackbone. The essence of the new Argentina, it's a wine that inspires and delights. Drink date: 2026-2035. Score - 99. (timatkin.com, Argentina Special Report 2023)

Quiet complexity that needs time in the glass. While it is brooding and deep, there is also a perfumed, floral and herbal aspect that makes it so attractive and unforgettable, even at such an embryonic stage. Freshly crushed blueberries, dried licorice, decadent violets, crushed stones and ash on the nose. Satin-textured tannins on the palate, which are tense, chalky and seamless. Powerful and juicy with impeccable balance. A great, cerebral and intrinsic malbec from Argentina. You can drink now, if you want, but it is a wine that you'd want to keep for the next two decades. A real charmer, especially for the wine nerds. Buy this and try! [Drink through mid-2030s.] Score - 99. (jamessuckling.com, Dec. 28, 2022)

Zuccardi has 38 hectares of vineyards surrounding the Piedra Infinita winery in Altamira that provide the grapes for several of its wines, including the outstanding Concreto, Finca Piedra Infinita, and Canal Uco. To a certain extent, those labels are the predecessors of this Supercal, a wine from a single block, the smallest unit in the vineyard so far. This year they made 1,800 bottles from that barely half-hectare block of limestone-rich soil, and the result is an enveloping wine with generous fruit as well as generous structure. The lime seems to leave its mark on the tannins, making them sharp and vertical. This is a very crisp malbec with great depth and length. A wine to drink immediately to taste the soil, or to open years from now to see how far that expression of place can go. [Will evolve for 15+ years from vintage.] Score - 99.

'If you'd told me I'd be selling an Argentinian wine at this price when I started, I would have laughed at you,' says Sebastián Zuccardi, but this remarkable red is worth every peso and more. Reflecting the hard work and talent of two complementary generations of Zuccardis, Gravascal is as brilliant as it is daring. Entirely concrete-fermented and aged, it's hauntingly complex stuff, with tangerine and dark berry fruit, thrilling minerality and precision, filigree tannins and a finish that lasts for over a minute. Truly world class, this is one of the two greatest young Argentinian wines I've ever tasted. Drink date: 2025-2040. Score - 100. (timatkin.com, Argentina Special Report 2022)

They used more grapes from places with a little more soil and resistance to heat and dry conditions in a warmer year like 2020 for the 2020 Finca Piedra Infinita, which feels very young, primary and undeveloped. They have 46 separate plots in the vineyard, and in this early harvest, they started picking earlier than ever but during the harvest still felt they were too late; but the wines show much better than anticipated. Having the palette of wines to choose from helps in warmer years, when it's more difficult to keep the freshness in the wine, which for them is one of the most important things. It really feels very young and better than expected. They told me they learned a lot from 2017 to manage a year like 2020, when they do a shorter maceration (and in cooler years, they might do a longer maceration). This is gentler than the 2019, with rounder tannins. Drink date: 2024-2032. Score - 98. (Luis Gutiérrez, robertparker.com, Nov. 30, 2022)

The grapes for the 2020 Finca Piedra Infinita Supercal were the first to be picked from the Piedra Infinita vineyard in the warm 2020 vintage, and the wine is built more around the fruit. It is juicy and pure and has similar levels of alcohol and acidity/freshness as the 2019, but of the two vintages, which I tasted side by side, this feels gentler and rounder. It has complexity despite its young age and has notes of orange peel, iron and blood, with the fine limestone sensation. The vintages are always very marked in this wine because the soil is very extreme and shallow and the vines can suffer in dry and warm conditions. Drink date: 2023-2030. Score - 98.

I'm splitting hairs here, because the level is so high in the Malbecs from the Piedra Infinita vineyard that it's difficult to say, but the coup de coeur is the 2019 Finca Piedra Infinita Supercal, the single-plot bottling from the shallower soils with lots of rocks covered in calcium carbonate (hence the name: 'superlime'). In a cooler year like 2019, this wine achieved a level of precision, austerity, elegance and balance that is amazing. The wine floats in the mouth, with an ethereal quality but with the clout and power from the place. The wine is juicy and fresh with a saline twist in the finish. This is approachable now because of its gobsmacking balance and elegance, but it has all the components and the balance between them to age for a long time in bottle. Bravo! 1,400 bottles were filled in June 2020. They told me that it's always a challenge to decide the picking date for this plot, and they feel they hit the bull's eye in 2019. And rightly so. Drink date: 2023-2035. Score - 100. (Luis Gutiérrez, robertparker.com, Nov. 30, 2022)

The one single-vineyard wine that is very different from the others is the 2019 Finca Los Membrillos, as it comes from a vineyard planted with Cabernet Sauvignon in Altamira two kilometers from the Piedra Infinita property planted 25 years ago. It keeps the herbal, spicy and peppery varietal character and the fine-grained tannins from the property and the chalkiness from the soils. It has 14% alcohol and good freshness, acidity and balance. This comes from four different soils and was co-fermented with some 10% Malbec from the same property, as they feel like that amount of Malbec gives it some lubrication/juiciness. This matured in used 500-liter French oak barrels (the last year they bought barrels was 2013). Drink date: 2022-2030. Score - 96. (Luis Gutiérrez, robertparker.com, Nov. 30, 2022)

Unlike Finca Piedra, Canal Uco comes from much deeper soils that may be giving the aromas and flavors a bit more exuberance?and those aromas and flavors are blue. Sebastian Zuccardi doesn't know why, but he relates it to the depth of the soils. In terms of winemaking, there are no differences. Both are made in concrete with some aging (less than 30% of the total) in used 500-liter barrels. There's an exuberance here that isn't common in the wines from Altamira, but beware, the tannins and imposing structure are felt almost as much as in the best examples from the area. But wait for it, because this is a wine for drinking in a decade, maybe more... Score - 97. (Patricio Tapia, guiadescorchados.cl, 2018)
