L’industria del vino è alla ricerca di continue novità per avvicinare nuovi consumatori al gusto del vino, approcciandoli con prodotti espressivi e con connotazioni “salutistiche”. Il settore dei prodotti vitivinicoli aromatizzati, regolamentato a livello europeo (Regolamento UE n. 251/2014), è il comparto che sta offrendo più innovazioni. Nell’ambito di queste aspettative abbiamo voluto testare l’uso del succo di melagrana su un vino spumante. In questo studio sono state eseguite due esperienze di rifermentazione. La prima spumantizzazione è stata eseguita con tre prove di rifermentazioni in bottiglia con un piccolo quantitativo di vino base Sangiovese, vinificato in bianco, per individuare, a livello organolettico e cromatico, la migliore proporzione di succo di melagrana (al 5%, al 10%, al 15%) da aggiungere come sostanza aromatizzante. La bevanda più gradevole a base di vino è risultata quella con la percentuale al 10%. Successivamente è stata replicata la rifermentazione in micro-autoclave, con vino base (cv. Glera) e succo di melagrana (al 10%), dove la possibilità di filtrare e di lasciare un residuo zuccherino hanno permesso di ottenere un prodotto ancora più gradevole al gusto e alla vista, dall’elevato potere antiossidante.

Abstract
In wine industry, wineries are propelled to innovate to bring new consumers to the taste of wine, approaching them with expressive products, and with connotations "healthy". The sector of aromatised wine products, regulated at European level (Regulation (EU) No 251/2014), is offering more alternative “wines”. The main goal of this thesis was to test the use of pomegranate juice on a sparkling wine. Two (second) fermentation experiments were carried out in this study. The first sparkling wine was made with three (second) fermentation tests in bottle, with a small quantity of Sangiovese base wine, vinified in white, to identify, at organoleptic and chromatic level, the best proportion of pomegranate juice (5%, 10%, 15%) to be added as a flavouring substance. The most pleasant aromatised wine-based drink was the one with the percentage at 10%. Subsequently the second fermentation was replicated in micro-autoclave, with base wine (cv.
