Researchers from the Institute of Agricultural and Fisheries Research and Training (IFAPA) from Jerez de la Frontera and Cordoba are using a concentrate of vineyard wood trimmings as a natural preserver of red wine.
Researchers have tested the properties of this extract to see if it can be used as a substitute to sulphuric acid. This additive, the most popular in wine production and conservation, distinguishes itself, according to experts through its antioxidant and antimicrobial capacity, but also through its possible negative health effects.
