The cellar’s ‘breathing’ for a quality wine: VOC A+ certification
The VOC A+ certification of Biopietra cladding ensures high indoor air quality, thanks to extremely low emissions of volatile organic compounds. This is a fundamental requirement in underground environments, where the microclimate directly influences the ageing of the wine.
The cellar’s microclimate and wine ageing
In underground cellars, it is essential to maintain optimal conditions of temperature, humidity and air quality, as these factors directly influence the wine ageing process. In other words, the cellar’s microclimate — that is, the set of environmental characteristics within the space where the wine is stored — has a tangible impact on the maturation and final quality of the product.
If the microclimate is not suitable, the wine may not develop its organoleptic qualities properly.
Wine Cellar Focus: Why is VOC A+ certification essential?
In a wine cellar, the air is not merely part of the ‘environment’; it is the element in which the wine ‘lives’ and breathes. Here are the specific benefits of a VOC A+ product in this sector:
Odour neutrality: volatile organic compounds (VOCs) can be absorbed by the wine, altering its aromatic bouquet. A VOC A+ stone ensures there are no ‘chemical odours’ or interferences that could compromise the product’s organoleptic characteristics.
Management of underground environments: cellars are often spaces with poor air circulation (to maintain constant temperature and humidity). In these enclosed spaces, the use of materials that do not emit toxic substances is vital for the health of staff and the quality of the microclimate.
Protection of biological heritage: the absence of aggressive volatile chemicals preserves the integrity of the yeasts and natural biological processes necessary for wine ageing.
Sustainability in ‘Luxury Wine’: for boutique wineries, A+ certification is a key selling point in regional marketing: it demonstrates that the entire building (not just the wine) meets organic and green building criteria.
