Montepeloso, located in the Val d'Orcia region of southern Tuscany, sits in a distinctive micro-terroir characterized by volcanic and calcareous soils. The vineyard encompasses south-facing slopes that receive optimal solar exposure, allowing for full fruit maturation across Cabernet Sauvignon and complementary varietals in the A QUO blend. The 2013 vintage was notably warm and dry, typical of southern Tuscany's continental-influenced climate, creating concentrated and ripe conditions for the Cabernet-based blend. The soils, enriched with mineral elements from volcanic activity, impart distinctive structure and depth. Montepeloso practises careful canopy management and selective harvesting to achieve the optimal balance of ripeness and acidity in this Tuscan Super Tuscan-style blend.

The 2013 A QUO harvest underwent careful selection and destemming, with fermentation in temperature-controlled conditions using indigenous yeasts. The Cabernet-based blend fermented separately by varietal, allowing the winemaker to optimize extraction for each component. Extended maceration extracted full tannin complexity and colour development. Post-fermentation, each varietal underwent malolactic fermentation to develop secondary flavours. The blend was assembled before oak ageing, which proceeded in French oak for approximately 18–24 months, with the percentage of new oak carefully calibrated to support rather than dominate the wine's character. Extended bottle maturation (2013 vintage is now mature) has allowed secondary flavours and tannin integration to develop.
