The vineyards for Testamatta are more than 35 years old, located in the Tuscan hills outside of Fiesole, overlooking the city of Florence. The wine is made from 100% Sangiovese planted on clay and galestro soil. The grapes are fermented in open top barriques of 225 liters with 6 to 8 manual punch-downs per day, and aged in French barriques for 18 months followed by 6 months in the bottle.

The 2020 Bibi Graetz Testamatta IGT is a notable Sangiovese from Tuscany, Italy. This vintage marks a significant step for Bibi Graetz, who has introduced grapes from his newly acquired vineyard property near Fiesole, incorporating about 30% to 35% of these cooler, high-elevation sites into the blend. The addition of these vines and the construction of a new winery have resulted in a production increase to approximately 150,000 bottles for the 2020 vintage.

Decanter awarded this wine a score of 94, noting its “darker character than the 2015” and describing it as “creamy, velvety and vertical with a lovely cherry character and an earthy background.” The review highlights the wine’s freshness but suggests that it “needs more time to uncoil.” Jeb Dunnuck also gave a favorable review with a score of 93, emphasizing the “scorched earth and pure sun-ripened fruit” and a “razor edge of acidity” that drives the wine forward. He recommends allowing the wine some aging time to reach its full potential.

James Suckling, who also rated the wine 94, praised its “beautiful, fresh aromas of sour cherries, orange peel, and lemon bush,” and its “racy acidity and ultra-fine tannins.” He highlighted the wine’s trend towards “crunchy, vivid Tuscany Sangioveses, which emphasize drinkability and transparency.” Robert Parker's Wine Advocate gave the highest rating of 95, noting the wine’s “beautiful clarity, sharpness and lifted bouquet” thanks to the new Fiesole fruit. This review underscores the wine's vibrancy and fresh acidity, calling it “a wine to watch.”

Vinous matched Decanter's score of 94, describing the wine as “dusty, floral and lifted with flinty crushed stone, peppery herbs and tart raspberry.” The review highlights the wine’s “seamlessly silky textures” and “fine-grained tannins.” Wine Enthusiast also gave it a commendable score of 93, appreciating the complex nose that releases “oak notes first, then cherries, soy sauce, herbs, pencil shavings, and eraser” with a palate that balances fruit and acidity.

The Wine Independent provided the highest praise with a score of 96, describing the wine as “a clear, transparent, ruby color” with “delicate, pure, red fruits like red cherry and wild strawberries.” They emphasized its “Burgundy-like weight and texture” and “juicy freshness and fine but firm, savory tannins.”

Overall, the 2020 Bibi Graetz Testamatta IGT is a well-regarded Sangiovese, characterized by its fresh acidity, complex flavors, and potential for aging.
