The 2017 Castello di Fonterutoli Siepi IGT is a proprietary blend red wine from Tuscany, Italy, crafted by Mazzei Castello di Fonterutoli. This vintage, with an alcohol content of 14%, features a complex array of flavors and aromas, appealing to those who appreciate a rich and layered wine.

James Suckling awarded this wine a high score of 95, describing it as having "polish and finesse," with a "full-bodied, dense and layered palate." He also noted its "chocolate, berry and hazelnut character," highlighting its integrated and textured finish. Suckling advises allowing the wine time to develop further refinement, suggesting it be tried after 2023.

Monica Larner of Robert Parker's Wine Advocate gave the 2017 Siepi a score of 91. She described it as "big-boned and chunky," with aromas of "tarry spice and tarmac." While noting the fruit is ripe, she pointed out the presence of blackberry and cherry preserves. Larner also remarked on a "pretty mineral note," a result of the wine’s time integrating in cement vats following 18 months in French barrique and large oak casks. However, she observed that this vintage matured quickly compared to its predecessor, the 2016 vintage, prompting a shorter suggested drinking window.

Wine Spectator's review, scored at 92, described the wine as having "black cherry, plum and tobacco flavors," characterizing it as "rich" and "fleshy." The review noted the wine's fruity upfront nature transitioning to a firmer finish where "cherry, almond and tobacco notes echo." It praised the wine for its "fine overall balance and length," recommending it be enjoyed through 2024.

Overall, the 2017 Castello di Fonterutoli Siepi IGT is a robust and sophisticated wine, with impressive reviews highlighting its rich flavor profile and potential for further aging.
