Riserva Madonna del Piano, hails from one of the first and best single-vineyard sites in Montalcino, with production dating back to 1977. Made only in the best vintages and from the oldest vines on the property, in 1994 Valdicava was granted the right to list the Madonna del Piano vineyard designation on the label. The 19.5 hectare single vineyard is divided into four parts: old vines, Pievecchina, Pratea and Sferracavallo. Owner Vincenzo Abbruzzese harvests the vines from each part of the vineyard at different times and makes the wines separately before blending them together. The wine is then aged about two years in large old casks and another two years in bottle.

The 2015 Valdicava Brunello di Montalcino Riserva Madonna del Piano is a standout red wine from Tuscany, Italy, specifically from the Brunello di Montalcino sub-region. Made from Sangiovese Grosso, this wine boasts an alcohol content of 14.0%.

James Suckling awarded this wine a perfect score of 100, describing it as having "spectacular aromas of crushed fruit, plums, sous bois, porcini and black truffles." He noted its decadence balanced by freshness, and praised its full-bodied, dense, and linear palate, highlighting its "incredible depth and consistency." Suckling also mentioned its "savory and juicy finish" with vivid acidity and fruit, calling it the "greatest ever" and recommending it for consumption after 2025 (jamessuckling.com, 1/26/2021).

Robert Parker's Wine Advocate, through reviewer Monica Larner, gave this wine a score of 96. Larner appreciated the balance between power and elegance, noting the presence of dried cherry, cassis, cranberry, and nuances of grilled herb, cola, and blue flower. She also highlighted the wine's balsam intensity with notes of root beer and rosemary oil.

Vinous reviewer Eric Guido awarded the wine 95+ points, highlighting its "mentholated freshness" and a "seductive display of crushed black cherries, cinnamon, sage and sweet white smoke."
