Wine cellar of the future

“The idea of an eco-sustainable winery is an idea that is not only consistent with current times, but inevitably projected towards the future. It is something more: the link between generations. "

Marilisa Allegrini

There are wine cellars constructed to tell stories of the men and women who have been carrying out their work with determination and resilience for years. Wine cellars that speak to us about blessed vintages and others that were less productive. Then there is San Polo’s wine cellar which is all of this and much more. A wine cellar created with the desire to keep the passion that has been handed down for generations, but with an eye always looking towards the future. Inspired entirely by the principles of eco-sustainability and sustainable architecture, it completely blends in with the surrounding landscape.

Virtual experience

The particular beauty of the landscape surrounding San Polo could not be tarnished by the construction of buildings that would compromise its natural harmony. We decided a virtual tour was an excellent way to explore the cellar, built according to the principles of sustainable architecture, and with the clever use of the earth’s generous natural resources.

Bio architecture

Modern and functional, our cellar was built in synergy with nature. Sustainable architecture means knowing how to interpret, through innovative construction techniques, ways to cleverly take advantage of environmental resources. In fact, the building’s cooling process occurs in a completely natural way. In the ageing area, the convex shape of the suspended ceiling directs the air to the sides of the room, which facilitates contact with underlying coils where cold water flows, allowing for the subsequent cooling. The microcirculation created as a result of these convective motions promotes a healthy environment and prevents the formation of moulds.

Underground Cellar

The cellar’s underground position allows the temperature to be kept constant throughout the year and greatly limits energy consumption. The structure’s tunnel shape fits perfectly into the Podernovi hill, and also allows for a logical and natural journey for the wine, from receiving the grapes to the vinification.

Solar vents

Placed outside and directly above the wine cellar, the vents take advantage of the area’s constant natural ventilation. They are made of lightweight aluminum, orient themselves according to the direction of the wind’s currents and, as a result of the Venturi effect, extract the hot air produced during fermentation.

Thermal matrix

This labyrinth of pipes runs along the entire structure and supplies a natural source of humid, cool air which is used to moderate the temperature of the cellar where the wine is ageing. The humidity, extracted from the hill’s soil, is introduced into the ageing cellar where the wooden barrels are arranged on special vents which  automatically close when the desired environmental parameters are achieved in the cellar.

Insulation

Made of hygroscopic tuff, it carries out an important regulating action in the barrel cellar. The porous stones absorb or release moisture, equilibrating the cellar’s environmental conditions.

Concrete tanks

The concrete tanks, with a vitrified lining, date back to the cellar’s construction. We take advantage of the cement’s thermal properties and there is no true “exchange” or contact between the cement itself and wine during fermentation. The tank has a coil filled with liquid that controls the temperature so that we can prevent excessive temperature increases. During fermentation, the temperature naturally begins to rise inside the tank and cement has the capacity to maintain warmth for a long time. The coil inside the concrete walls is not obstructive, unlike versions made with a thermal plate. And from a hygiene standpoint, cleaning is also easier and more effective.

Stainless steel tanks

Vinification takes place in stainless steel tanks for a fresh and modern take on winemaking. Stainless steel is an inert material in terms of gas exchange and this feature means we can produce a pure wine which highlights the grapes’ innate qualities. We use stainless steel when our goal is to extract the fruit’s aroma without the vessel’s interference or influence, the opposite objective of using wood and amphora. In San Polo the stainless steel tanks are used for the production of Rubio. The wine is kept cool and there is no microoxygenation, which allows the development of natural fruity aromas without the need for compounds used for refinement or evolution. Stainless steel is an excellent conductor of heat and these tanks are perfect when it is important to control the temperature quickly and easily.

Small barrels

The barrels produced with French wood can hold 500 and 600 litres and 10 hectoliters and certainly leave more of an impact, giving the wine particular characteristics from the aromas and properties of the wood itself, especially in the smaller barrels. The wood’s shape and style become fundamental to supporting the structure of a wine like Brunello di Montalcino Vignavecchia, which ages in 600-litre French wood barrels.

Large barrels

The large barrels made of Slavonian wood have capacities of 10, 20, 25, 40 and 80 hectolitres. They are used for the delicate ageing of elegant and intense wines like Brunello di Montalcino Podernovi and younger wines like Rosso di Montalcino.
