92 Monica Larner - Robert Parker's Wine Advocate

The 2020 Guidalberto is taut and tight with plenty of tart cherry and wild berry. The wine offers great freshness and tension with bay leaf, spice, wild cherry and pressed lavender buds. There is a hint of black olive too. The blend is equal parts Cabernet Sauvignon and Merlot.

92 Antonio Galloni - Vinous

The 2020 Guidalberto is a gorgeous, classy wine. Less opulent than it can be, the 2020 impresses with its energy and drive. Sweet red cherry, plum, mint, rose petal, cedar and pipe tobacco all take shape in this super-attractive, mid-weight offering from Tenuta San Guido. There's a bit more Merlot in the 2020, but Guidalberto is increasingly made from lots that don't make it into Sassicaia, which explains the style of recent vintages. This is a terrific showing, especially considering the recent bottling. It's a fine relative value in Bolgheri's high-rent district. (Originally Published in March 2022)

Nice freshness on the palate with plums and berries and citrusy acidity. It’s medium-bodied with fine tannins and a powdery texture. Hints of mushrooms. You can enjoy this young, but it will age nicely, too. Drink or hold.
