Alta Alella, committed to sustainability

From vine to bottle: investing in vineyards

Located in the Serralada de Marina Natural Park, the Pujol-Busquets Family has always been committed to nature and sustainability. Organic since the beginning, their path has been to invest in the land, the vineyards, and being in control of the whole winemaking process.

The vineyards have a very positive impact on the ecosystem in the surroundings of Barcelona and contribute to organize the territory, providing natural landscape value, as well as working as a firebreak. The winery works with small plots, which respect the orography of the valley as much as possible, maintaining the forest areas between vineyards. This enhances biodiversity, prevents the appearance of pests and soil erosion, and has a positive impact on the wine quality.

Reducing carbon footprint

Since 2021, Alta Alella is one of the Catalan companies adhered to the “Voluntary Agreements Program” promoted by the Generalitat de Catalunya (Catalan Government) and the United Nations. This implies a commitment from the winery to monitor Greenhouse gases (GHGs) emissions and establish annual measures in order to reduce them.

In 2023, Alta Alella was certified with the UNE-EN ISO 14064-1:2019 (official certification to calculate the carbon footprint with which the winery commits to reduce its CO2 emissions throughout the whole process from production to sales) and the UNE-EN ISO 14001:2015 (official certification to implement an Environmental Management System (EMS) in all the areas of the winery).

Renewable energy: solar power

At the end of 2022, Alta Alella installed a hundred solar panels on the winery’s roof to produce and consume its own energy in a clean and non-polluting way. These generate up to 50Kw of energy, which is the amount needed for a workday in the winery except during the harvest season.

Reused bottles and packaging reduction

Since 2006, all the wines from Celler de les Aus are released in reused bottles (80,000 annually).

In mid-2023, Alta Alella started a new system of reusing the bottles consumed at the Wine Tourism Center, with a rigorous process of conditioning and sanitization by the Catalan start-up POTS.

Little by little, the winery is also implementing other changes that help to generate less waste and reduce the carbon footprint, such as replacing capsules with wax or working with lighter bottles.

Developing disease-resistant plants and adapted to Climate Change

In 2012 Alta Alella embarked on a viticulture research project to develop Resistant and Autochthonous Varieties Adapted to Climate Change (VRIAACC in Catalan: Varietats Resistents i Autòctones Adaptades al Canvi Climàtic).

Obtaining new plants through sexual reproduction is a long road, but the results of microvinifications obtained so far are encouraging and the advantages for viticulture are still unimaginable.

The main objectives of this project are to obtain plants resistant to downy mildew, powdery mildew, induced botrytis (not very compact bunches), Drosophilia Suzuki (thick skin) and drought, and also a delay in ripening (2-3 weeks) and low secondary buds.

Thanks to this innovative viticulture, other improvements will also be obtained, such as 90% less treatments, lower production costs, less soil compaction, working in a healthier environment, reducing CO2 emissions, avoiding the effects of climate change and reducing production loss due to pests, among others.
