Taninurile enologice sunt compu\u0219i fenolici de origine vegetal\u0103 care joac\u0103 un rol fundamental \u00een structura, stabilitatea \u0219i expresia senzorial\u0103 a vinurilor. Prezen\u021bi \u00een mod natural \u00een p\u0103r\u021bile solide ale strugurilor (pieli\u021b\u0103, semin\u021be, ciorchini) sau ad\u0103uga\u021bi exogen, taninurile au trecut de la a fi considera\u021bi un component pasiv al vinului la a deveni un instrument strategic \u00een enologia modern\u0103.<\/div>\n

C\u0103utarea de profiluri organoleptice diferen\u021biate, necesitatea de a compensa dezechilibrele cauzate de schimb\u0103rile climatice \u0219i evolu\u021bia gusturilor consumatorilor au plasat taninurile \u2014 \u00een special cele de rafinare \u2014 ca alia\u021bi indispensabili pentru ob\u021binerea unor vinuri stabile, expresive \u0219i adaptate diferitelor pie\u021be.<\/div>\n<\/div>\n<\/div>\n

Provin din \u021besuturi vegetale precum semin\u021be, pieli\u021be sau tulpini. Sunt forma\u021bi din flavonoide polimerizate, iar gradul lor de polimerizare influen\u021beaz\u0103 comportamentul lor enologic (astringen\u021b\u0103, reactivitate, solubilitate). De exemplu, taninurile din semin\u021be au un grad mediu de polimerizare de 11, \u00een timp ce cele din pieli\u021b\u0103 ating valori de 30.<\/div>\n
<\/div>\n
Tanicol Vintage este un exemplu reprezentativ de tanin condensat: 100 % pe baz\u0103 de semin\u021be de struguri, se caracterizeaz\u0103 prin reactivitate ridicat\u0103, putere antioxidant\u0103 \u0219i capacitatea de a \u00eembun\u0103t\u0103\u021bi stabilitatea colorantului.<\/div>\n<\/div>\n<\/div>\n
