The many organoleptic benefits of adding oak fragments to wine vary according to the botanical source of the wood, to fragment size, to toasting intensity and to the treatment received. Not all wines age in the same way when treated with oak fragments.

Natural fragments are principally characterized by their antioxidant properties and, thanks to their ellagitannin content, by their capacity to help stabilize colour in red and rosé wines. They also help enhance the wine’s structure by increasing the sensation of volume in the mouthfeel, add sweetness (thanks to the oak’s polysaccharides) and help preserve varietal characteristics by absorbing the volatile compounds in the wine that produce undesirable aromas.

Toasting reduces the amount of some compounds and produces other new ones (final content varies according to toasting temperature). The main aromas produced by medium toasting derive from eugenol (clove, pepper and cinnamon) and whisky-lactone cis- and trans-isomers (coconut and vanilla). In contrast, intense toasting predominantly produces compounds derived from heat degradation of cellulose and hemicellulose, such as furanic aldehydes (caramel, smoke, toasted and butter aromas). It also produces vanilla aromas, though in this case they derive from vanillin, a low-molecular-mass polyphenol produced by heat degradation of lignin.

The SPIRIT range of ageing alternatives is derived from a variety of oak sources and is available in several formats and toasts designed to modulate and increase wine complexity.

With SPIRIT Quercus pyrenaica, a nuance-rich ageing alternative derived from Pyrenean oak, Agrovin firmly commits to sustainable management of the Iberian Peninsula’s native oak forests.

The SPIRIT range’s properties are listed below. Click on the references for further information:
