Atunci c\u00e2nd vorbim despre aroma vinului, apreciem diferite aspecte ale acesteia ca \u00eentreg. Soiul de struguri, tipul de vinifica\u021bie, caracterul dorit sau procesul de \u00eenvechire sunt responsabile pentru calit\u0103\u021bile organoleptice ale vinurilor, complexitatea aromatic\u0103 fiind una dintre primele care au un impact asupra consumatorului, d\u00e2nd astfel na\u0219tere la o evaluare a calit\u0103\u021bii acestuia.<\/p>

\u00cen timpul recoltei, au loc o multitudine de procese fizice, chimice \u0219i biologice care au ca rezultat eliberarea, producerea \u0219i transformarea compu\u0219ilor volatili, de a c\u0103ror evolu\u021bie va depinde calitatea vinului final. Din acest motiv, este deosebit de important s\u0103 se asigure \u00een acest moment at\u00e2t absen\u021ba defectelor (GARAN\u021aIA DE FERMENTA\u021aIE<\/a> \u0218I BIOCONTROL<\/a>), c\u00e2t \u0219i sporirea eficien\u021bei procesului din diferite puncte de vedere: extrac\u021bie, metabolism \u0219i conservare.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ob\u021binerea unui vin cu o expresie varietal\u0103 maxim\u0103 \u00eenseamn\u0103 \u00eembun\u0103t\u0103\u021birea extrac\u021biei compu\u0219ilor aromatici \u0219i polifenolici \u00een timpul macer\u0103rii strugurilor. Transferul compu\u0219ilor de interes organoleptic va avea loc at\u00e2t \u00een timpul fermenta\u021biei alcoolice, favorizat de ac\u021biunea de solvent a alcoolului, c\u00e2t \u0219i \u00eenainte de fermentare, deoarece anumi\u021bi compu\u0219i, cum ar fi precursorii aromatici sau antocianii, sunt difuza\u021bi \u00een faza apoas\u0103.<\/p>

\u00cen cazul vinifica\u021biei \u00een alb, macerarea \u0219i stabula\u021bia pe pieli\u021b\u0103 sunt favorizate de utilizarea preparatelor enzimatice<\/a> \u0219i reprezint\u0103 strategii pentru un transfer mai mare de precursori aromatici varietali. \u00cen cazul vinurilor ro\u0219ii, o bun\u0103 umezire a fazei solide este esen\u021bial\u0103 pentru o extrac\u021bie corect\u0103. \u00cen acest scop, este necesar s\u0103 se garanteze o rupere eficient\u0103 a capacului (sistemul Ulise<\/a>) care s\u0103 \u00eempiedice formarea de canale preferen\u021biale prin care trecerea mustului nu ar permite extragerea aromelor \u0219i a polifenolilor din zonele f\u0103r\u0103 contact \u00eentre must \u0219i pieli\u021be.<\/p>

Progresele tehnologice \u00een domeniul oenologiei au f\u0103cut posibil\u0103 demonstrarea modului \u00een care aplicarea ultrasunetelor de mare putere \u0219i de joas\u0103 frecven\u021b\u0103 faciliteaz\u0103 eliberarea precursorilor aromatici localiza\u021bi \u00een celula vegetal\u0103, precum \u0219i a compu\u0219ilor polifenolici din vinurile ro\u0219ii. Sonicarea strugurilor dup\u0103 recep\u021bia \u0219i desciorchinarea cu ajutorul sistemului ULTRAWINE – PERSEO<\/a> provoac\u0103 un colaps \u00een celula vegetal\u0103, cu o ruptur\u0103 a structurilor care formeaz\u0103 \u0219i con\u021bin ace\u0219ti compu\u0219i, favoriz\u00e2nd eliberarea lor \u00een mediul \u00eenconjur\u0103tor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
