Il paesaggio delle alberate aversane ed il vino Asprinio

Abstract

[English version below]

Nel corso del 2009, in alcuni vigneti allevati ad alberata in provincia di Caserta (Italia), è stata avviata una ricerca per valutare la variabilità genetica della popolazione del vitigno ‘Asprinio’, la condizione sanitaria delle piante e le caratteristiche del vino sia rispetto alla forma di allevamento (alberata tradizionale e controspalliera) che all’altezza della fascia produttiva. I primi risultati indicano la totale omogeneità genetica della popolazione del vitigno ‘Asprinio’, non essendo stati ritrovati campioni vegetali riferibili a biotipi diversi. I saggi immunoenzimatici ELISA hanno rilevato la presenza di GLRaV 1, GLRaV 3 e GVA in tutti i campioni, mentre l’analisi delle molecole aromatiche delle uve e dei vini, condotta mediante analisi SPME-GC/MS, ha messo in evidenza che le uve ‘Asprinio’, prodotte sulla fascia più bassa delle alberate, presentano una maggiore potenzialità aromatica, rispetto a quelle della fascia più alta o delle controspalliere. I vini prodotti con diversi protocolli mostrano parametri enologici (grado alcolico, livelli di pH a acidità totale) simili tra di loro ed a quelli riportati da autori della metà del XX secolo.

During 2009, in some vineyards grown on trees (alberata) in the province of Caserta (Italy), a study is carried out to assess the genetic variability of the ‘Asprinio’ grapevine population, the health condition of the plants and the features of the wine in relation to the breeding system (traditional alberata vs horizontal training system) and to the heigth of fertile shoots. The first results point out the genetic identity of the ‘Aprinio’ grapevine population, because no different bio-types were found. The immunoenzymatic essays ELISA revealed that all the accessions were infected by GLRaV 1, GLRaV 3 and GVA; whereas the determination of the aromatic molecules from grapes and wines, performed by SPME- GC/MS analysis, indicated that the ‘Asprinio’ grapes, grown on lower area of the alberata, show greater aromatic potential than those from highest level of the same or those from vertical training system. The wines, produced by different procedures, show oenologycal parameters (alcohol degree, pH and total acidity level) similar to each other and to those reported by some authors of the mid-twentieth century.

Use of chitosan as a secondary antioxidant in juices and wines

Chitosan is a polysaccharide produced from the deacetylation of chitin extracted from crustaceous and fungi. In winemaking chitosan is mainly used in the clarification of grape juice and wine, stabilization of white wines, removal of metals and to prevent wine spoilage by undesired microorganisms. The addition of chitosan to model wine systems was able to retard browning, reduce levels of metallic ions (Fe and Cu) and to protect varietal thiols due to its antiradical activity1. The present experiment was planned in order to evaluate the use of chitosan as a secondary antioxidant at three different stages of Sauvignon blanc fermentation and winemaking. Sauvignon blanc juices from three different locations were obtained at a commercial winery in Marlborough, New Zealand. One lots of grapes was collected from a receival bin and pressed into juice with a water-bag press, and a further juice sample was collected from a commercial pressing operation. Chitosan (1 g/L, low molecular weight, 75 – 85% deacetylated) was added to the juice after pressing, after cold settling, after fermentation, or at all these stages. Controls without any chitosan additions were also prepared.

The effect of wine cork closures on volatile sulfur compounds during accelerated post-bottle ageing in Shiraz wines

Reduced off-flavour is an organoleptic defect due to an excess of volatile sulfur compounds (VSC) in wine and often happening in Shiraz wines. This off-flavour is a direct consequence of the lack of oxygen flow during winemaking and bottle storage. Therefore, wine closure could have a direct impact on the formation of VSC due to the oxygen transfer rate that can modulate their levels. Even if dimethylsulfide (DMS) contributes to reduced off-flavor, it is also a fruity note enhancer in wine and its evolution during wine ageing is not well understood.

Organic volatile compounds as suitable markers of grapevine response to defense elicitors in the vineyard

In greenhouse, emission of volatile organic compounds (VOC) by grapevine leaves has already been reported in response to the defence elicitor sulfated laminarin (PS3) [1]. In order to check that this response was not specific to PS3, experiments were conducted on Vitis cv Marselan plantlets with several other elicitors of different chemical structures: i.e. Bastid® (COS-OGA),

Colour assessment of port wines using colorimetric and spectrophotometric methods

Colour is an important quality parameter in wines and is the result of a complex mixture of pigments
(including anthocyanins and their derivatives, quinones, xanthyllium compounds, etc.). Red wine colour changes over time as pigments react between themselves and with other wine macromolecules
(particularly polyphenols). During wine tasting, colour is normally assessed on the outer rim of the wine profile in a tilted glass, since most wines are too opaque to be analysed in the middle of the glass. Therefore, depending on the depth of observation considered, the perception of wine colour can be different.

Corvina berry morphology and grape composition as affected by two training system (Pergola and Guyot) in a context of climate change scenario

The Valpolicella area (Veneto Region, Italy) is famous for its high quality wines: Amarone and Recioto, both obtained from partial post-harvest dehydrated red grapes. The main cultivars used for these wines are Corvina and Corvinone. In this Region hundreds of years ago a particular training system (Pergola, cordon/cane with horizontal shoot-positioning) was developed. In the last 20 years the Guyot have been introduced in the area; now Pergola and Guyot are equally widespread in the Valpolicella area. In two different environmental conditions (hill and floodplain) two vineyards, one for each type of training system, were studied along two years (2011-2012).
