Corked wines preserve the sensory quality better than BiBs

Recently there is a boom in wines packaged with the so-called system Bag in Box (BiB), but what do we know about its relationship with the wine it wraps? What disadvantages does it have with respect to the Cork?

According to the study “Influence of packaging and aging on the red wine volatile composition and sensory attributes” BiB wines have a higher level of some carbonyl compounds (propanal, hexanal, 3-methyl-1-butanal, benzaldehyde, phenyl acetaldehyde, 2-butanone, 2-pentanone, 3-penten-2-one and furfural) in more of lower sensory attributes than wines packaged in glass bottles closed with natural cork.

In addition, the study points out that some compounds that are associated with the freshness and fruitiness of wines are present at higher levels in corked wines, which leads to the conclusion that the sensorial quality of corked wines is preserved better than in the case of wines packaged with BiB.

Development of the study

"Influence of packaging and aging on the red wine volatile composition and sensory attributes" consisted of the study of the volatile composition of the sensory properties of red wines after being packaged with the Bag in Box systems and with glass bottles covered with natural cork The work was carried out for 12 months and the analyzes were carried out just before the wines were bottled, after 3 months of storage, 6 and 12 months.

The tasks of determining the volatile compounds were carried out using two analytical techniques: HS-SPME and GC-IT /MS. The results showed that one year after storage, BiB wines were characterized by higher levels of various carbonyl compounds than those covered with natural cork and by premature development. Wines with natural cork, on the other hand, retained more sulfur dioxide than BiB.

Cork bonanzas

The Catalan Institute of Cork Foundation always recommends the use of cork, the only cap that contributes to the positive evolution of bottled wines and is 100% sustainable.

It is also a natural, recyclable, reusable material that does not generate waste and has a positive environmental impact, as it retains more carbon dioxide than it emits.
