Soil, Microclimate & Vines

Castello di Potentino’s wines are representative of the delicate relationship between nature and the human, earth and the climate; a symbiosis based on observation and respect, sensibility and discipline. Due to our unique micro-climate and mixed volcanic soil we are able to grow 3 of the most site sensitive varieties together in one small vineyard – Pinot Noir, Sangiovese and Alicante.

Just 30km from Montalcino, bordering on the Brunello di Montalcino DOCG, Castello di Potentino is in the newly founded Montecucco D.O.C region. All the wines are I.G.T.

Micro-climate, micro-life and soil

The land lies in a sheltered valley used since Etruscan times for the production of wine. This continuous tradition exists thanks to the very particular microclimate of the area surrounding the Castle and it contributes to a uninterrupted build up of micro-life and yeasts. There is no mono-culture in the valley and modern farming techniques, including mass use of herbicides and pesticides, have not impacted the area. As a result, wild animal, bird, insect (bees in particular) and plant life abound whilst there are many fruit trees, especially cherries and olives. These are all elements which create a healthy and vigorous ecosystem which is extremely rare in this day and age.

The vineyards are only at 350m but benefit from higher altitude conditions being directly underneath Monte Amiata, the highest mountain in Tuscany and an ex-volcano. At night, during the summer, the vineyard is cooled by the mountain air and very well ventilated by dry, hot air drawn off the sea and coastal plains during the day.

The valley itself is shaped like a basin and very well protected. This crucible-like form has ensured that, unlike other areas of the Amiata where there has been erosion, volcanic matter has been gathered and blended, not washed away. The soil is mixed volcanic - marly schist, calcite, and quartz on a bed of metamorphic marine clay. With this mineral rich, geologically new volcanic soil and extreme changes in temperature, Potentino is the ideal location for photosynthesis and the concentration of the natural sugars needed to make a fine and elegant wine.
