Just south of Panzano are the 100 acres of planted vineyards that comprise il Molino di Grace. The soil composition is Galestro, a combination of marl and limestone. The vineyards have different ages: vineyards already existing when the winery was founded are on average 25 years old. 15% of the vineyards have been replanted (the youngest used in the production of wine is 7 years old.) The dominant variety is sangiovese, with small quantities of cabernet sauvignon, merlot, syrah and canaiolo. The density in the older vineyards is around 3,000 plants per hectare (1,210 per acre). However, the vineyard producing the Gratius is the oldest (about 55 years) and highest-elevation.
