At the end of a long day at Mendoza’s Nieto Senetiner, my friends and I toasted a beautiful evening and the long-term partnership between viticulturalist Tomas Hughes and winemaker Roberto Gonzalez, who have been making wine together for over twenty years. We’d tasted many of their “children” — beautiful malbecs and a vertical of the best bonarda I’ve ever had — and finished the night with a lovely rosé sparkling wine, a pinot noir with a touch of malbec, topped with a bit of grappa in the bottle. Salud!
