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.
