"Apricots, cantaloupe, mangoes and papaya make for a very tropical-fruited semillon. Medium to full body, lots of tangy acidity and a textured finish. Drink now."
92 points Robert Parker's Wine Advocate
"The one white produced at Mendel, the 2017 Semillon is sourced from 70-year-old vines in Paraje Altamira at 1,100 meters in altitude. 2017 saw lower yields because of a late frost, and the vintage produced concentrated, aromatic grapes that give freshness to the wine, with citrus and floral aromas. The whole clusters were pressed, and 15% of the volume fermented in French oak barrels and then matured in those barrels for six months; the rest of the wine fermented in stainless steel and was kept there until it was blended and bottled in September 2017. Sémillon and Chenin Blanc were riper in 2017 compared to 2016, which was a very rainy vintage when these varieties had some issues with ripening properly. In years like this, Roberto de la Mota likes to ferment with indigenous yeasts, because there is no need to add any yeasts. He also likes to do an oxidative vinification to stabilize the wine and uses very low sulfur. The wine comes through as very balanced—on both the nose and palate—clean, integrated, faintly balsamic and with very good intensity while keeping the freshness. It opens up slowly in the glass, becoming more nuanced and complex. It should develop nicely in bottle."
90 points Vinous
"Bright, light, green-tinged yellow. Musky aromas of herbs and flowers on the reticent nose. Then wonderfully silky and fine-grained, with terrific mineral energy contributing to the wine's impression of dryness. Still, there's a lovely sweet core of fruit here, with good supporting acidity (the pH is a low 3.15, according to de la Mota). Finishes with sneaky subtle length. De la Mota, who doesn't find this to be a particularly warm vineyard, noted that especially warm vintages like '12, '09 and '06 yielded wines with more tropical fruit character. This bottling typically becomes more honeyed and hazelnutty with aging."
Vinous Reverie Notes
Mendel Semillon is the maximum expression of these old strains in Argentina in a tranquil wine. In the nose it shows typical notes of white flowers and honey, also some herbal notes and tropical fruits. The oak ageing makes the wines more complex, lending coconut and hints of smoke, as well big volume and softness in the mouth. Mendel Semillon is a complex, elegant and agreeable wine.
