Robert Parker's Wine Advocate - 97 points: "I've been tracking the increasing percentage of Cabernet Franc in the blend of this iconic Tuscan wine. The 2019 Bolgheri Superiore Guado al Tasso is made with 25% Cabernet Franc, with 60% Cabernet Sauvignon and 15% Merlot. That this heat-resistant grape now makes up a quarter of the blend speaks to how vintners are gearing up to counter climate change. These are intelligent choices, and you can count on this wine to maintain that level of extreme elegance and intensity that it is known for (even when Merlot was a bigger part of the blend). Indeed, this is a new and improved Guado al Tasso with focused aromas of pencil shaving, white pepper and crushed stone that frame a rich core of black fruit. A fluttering of dried mint gives lift and power to the bouquet. This is a beautifully linear and powerful red blend."
