Indigenous yeast communities in the environment of ‘‘Rovello bianco’’ grape variety and their use in commercial white wine fermentation

2009

The indigenous yeast communities associated with several vineyard habitats were analysed. Wild yeasts were isolated, differentiated at strain level and identified. A phylogenetic tree based on partial 26S rRNA genes was constructed. The strains were characterized and the indigenous Saccharomyces cerevisiae GR1 was then used to carry out a vinification process and compared with a commercial yeast. Wines obtained were subjected to chemical and sensory analysis. The comparison between the two products highlighted differences due to the fer- menting strains employed. The vineyard environment was found to strongly influence the composition of yeast communities, thus, confirming the theory of ‘te…

Rovello bianco, caratterizzazione di un vitigno autoctono campano.

2009

Il “Rovello bianco”, conosciuto localmente come “Greco muscio” nuovo vitigno autoctono campano è stato oggetto di uno studio triennale (2004-2005) considerando il “Fiano” come varietà di riferimento. L’analisi molecolare mediante marcatori micro satelliti (SSR) ne ha stabilito l’unicità del profilo genetico. La valutazione agronomica è stata ottenuta attraverso annuali e sistematici rilievi, effettuati su 50 piante di 5 anni di età, registrando da parte del “Rovello bianco” un più basso vigore vegetativo rispetto al “Fiano” e una buona resistenza alle più diffuse fitopatie. Ben distinta dal vino “Fiano” è risultata invece la componente organica volatile. Principalmente alcoli isoamilici qua…
