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.Robert Parker | 100 RPThe 2019 Malbec Finca Piedra Infinita Supercal from Paraje Altamira, Uco Valley was aged in concrete and made with grapes from a parcel of soils rich in calcium carbonate. It’s purple in hue. The 2019 has an austere aromatic profile in which clear fresh plum notes are accompanied by violets, lavender and bay leaf. It’s compact yet juicy in the mouth with a pure, chalky texture. The structure is linear for a Malbec, almost skeletal in fact, ensuring that the flavors at the back of the throat reverberate with a mixture of delicate aromas over the taut palate. This wine is a successfully executed statement about winemaking and the house style.Vinous Media | 98 VMDeep but scented nose of black cherries, blueberries, dried violets, graphite, ink and chalk. Very primary, and certainly all about the intrinsic side of the fruit. White pepper and fleshy, deep black cherries on the palate. The tannin is immaculate, but so powerful, with fine austerity, which is evenly distributed, but in an electric way, seeping into the naturally concentrated and succulent fruit. Violets and spices in the finish. Probably the most powerful of the three Piedra Infinita range of reds tasted. An intellectual, austere but resolved malbec. Look elsewhere if you are after oak plushness. Intrinsic and beautiful. Around 1,000 bottles made. Unique. Better after 2025.James Suckling | 98 JS
