Alvinesa is the biggest industrial complex in the world producing wine alcohols, tartaric acid and seed oil as well as grape anthocyanins and polyphenols.
We’ll now describe the most important facilities.
The Alvinesa Laboratory
All goods that enter our factory are analysed at our laboratory and exhaustive quality monitoring is done on all semi-finished and finished products.
Pursuant to ISO standards, our technical department confirms whether the products are suitable for sale so that we may comply with our customers’ rigorous demands.
Our quality and R+D+i department works pursuant to ISO 9001 quality, 14001 environmental and OHSAS 18001 occupational risk prevention certification progra
Pomace washing and drying facilities
Once the pomace washing process finishes, we obtain the piquette and send it to our dryers already dealcoholised.
The pomace drying process obtains grape seed to produce crude seed oil and biomass, which is used in our boilers to produce thermal energy and sold to third parties.
Alcohol production facilities
We have devices to produce different types of alcohol, for industrial use and as a beverage.
Grape seed oil extraction
The grape seed oil extraction plant has a monthly production capacity of 900 tonnes of raw oil.
We have a concentrator to produce anthocyanins and polyphenols with the possibility of concentrating the tartrate wealth from our effluents.
Tartrates and tartaric acid
At our tartrate plant, we process piquettes and lees to extract the calcium tartrate, which is the raw material used to obtain natural tartaric acid.
The tartaric acid production process consumes all the tartrate generated by our production process as well as the tartrate supplied by our suppliers.
We have high storage capacity tanks for raw materials and finished products.
Environmental safety and protection
We have a sophisticated fire-fighting system that specially focuses on our alcohol tanks and other facilities to comply with all of the safety requirements established by law.
We are very much committed to sustainability and have been approved by the Regional Ministry of the Environment under the supervision of the University of Castilla La Mancha for our program which valorises the effluents we store in basins for later use in the irrigation of our 500 hectares of agricultural land.
Likewise, we have installed a smoke filter in compliance with environmental regulations on emissions into the atmosphere.
