\n Nu sun\u0103 foarte interesant, \u00een\u021beleg. Dar tocmai aici, probabil, au ap\u0103rut cele mai importante descoperiri din ultimele decenii \u00een lupta pentru calitatea vinului.\n <\/p>\n

<\/p>\n

\nAcum 20 de ani plut\u0103 natural\u0103 a fost, practic, un monopol \u00een mijloacele de plafonarea sticle de vin. \u0218i ea a putut face fa\u021b\u0103 cu acest r\u0103u, sincer. \u00cen special, australienii s-au s\u0103turat de problemele cu \u0437\u0430\u043a\u0443\u043f\u0430\u0435\u043c\u044b\u043c\u0438 dopuri: evaluare au variat, dar, \u00een general, de p\u00e2n\u0103 la 10% de vinuri \u00een gospod\u0103riile au fost \u0437\u0430\u0433\u0443\u0431\u043b\u0435\u043d\u044b din cauza „plut\u0103 boala” sau prematur\u0103 oxidate din cauza unor probleme cu ea. Problema c\u0103ut\u0103rii de alternative a fost foarte grav\u0103.\n<\/p>\n

\nMai \u00eent\u00e2i au \u00eenceput s\u0103 \u00eencerce dopuri din plastic.\n<\/p>\n

\nSintetice prima genera\u021bie a fost f\u0103cut\u0103 prin turnare sub presiune \u0219i puternic \u0443\u0441\u0442\u0443\u043f\u0430\u043b\u0430 moderne modele. \u00cen ciuda neajunsurilor (dintre care unul a fost dificultatea de a scoate dintr-o sticla), aceste dopuri au modest, dar rata de succes la mijlocul anilor 1990.\n<\/p>\n

\nAlte principalul pretendent la schimb a devenit un surub capac. Ei au \u00eencercat s\u0103 introduc\u0103 \u00een Australia \u00eenc\u0103 din 1970\u0445, dar consumatorul nu a \u00een\u021beles, \u0219i a e\u0219uat.\n<\/p>\n

\nRe-abordare a \u0441\u043d\u0430\u0440\u044f\u0434\u0443 avut loc \u00een 1999\u043c, atunci c\u00e2nd produc\u0103torul Orlando a decis s\u0103 \u00eenchid\u0103 afacerea catarg riesling cum tradi\u021bionale dop, c\u00e2t \u0219i \u0219urub capac. \u00cen cele din urm\u0103 de v\u00e2nzare elicoidale sticle de ocolit tradi\u021bionale. \u0218i apoi, \u00een 2000m mai mul\u021bi produc\u0103tori de Clare Valley s-au unit \u0219i dintr-o dat\u0103 \u0219i-au lansat propria \u0440\u0438\u0441\u043b\u0438\u043d\u0433\u0438 cu \u0219urub capac, \u0441\u043e\u043f\u0440\u043e\u0432\u043e\u0434\u0438\u0432 este mare \u0448\u0443\u043c\u0438\u0445\u043e\u0439 \u00een mass-MEDIA.\n<\/p>\n

\nUrme de vinificatorii din Noua Zeeland\u0103, de asemenea, s-au gr\u0103bit s\u0103 \u00een\u0219uruba\u021bi lor proaspete \u0441\u043e\u0432\u0438\u043d\u044c\u043e\u043d\u044b \u043d\u043e\u0432\u043e\u043c\u043e\u0434\u043d\u044b\u043c\u0438 rola.\n<\/p>\n

\nAstfel, noi cu privire la \u0219tiin\u021b\u0103.\n<\/p>\n

\nApoi, la toate a fost o idee, c\u0103 rolul de plut\u0103 \u2013 astupa\u021bi sticla, ca nu a p\u0103truns aerul \u0219i nu a rezultat de vin. Ceea ce nu aveau, deci, este de a \u00een\u021belege rolul jucat de plut\u0103 accesul \u00eentr-o sticl\u0103 de micro-doze de oxigen \u0219i marea impactul ultima la starea \u0219i dezvoltarea de vin \u00eentr-o sticl\u0103.\n<\/p>\n

\n Cercetare de pionierat a acestui subiect a devenit Australian Institutul de Cercetare a Vinului (AWRI), descoperitorul tuturor ochii la minunile vinului de chimie \u00eentr-un flacon \u00eenchis.\n<\/p>\n

\n\u00centr-un studiu figurat acela\u0219i vin \u2013 \u043d\u0435\u0432\u044b\u0434\u0435\u0440\u0436\u0430\u043d\u043d\u044b\u0439 din lemn de stejar \u0441\u0435\u043c\u0438\u0439\u043e\u043d 1999 de Clare Valley \u2013 \u00eenchis 14 diferite tipuri de trafic. Toate sticlele au trecut testele de gust \u0219i in vitro la intervale egale de timp. Pe scurt, rezultatul este: dopuri sintetice, utilizate \u00een acest experiment, ratat prea mult oxigen, ceea ce a dus la \u00eemb\u0103tr\u00e2nirea prematur\u0103 \u0219i \u043f\u0435\u0440\u0435\u043e\u043a\u0438\u0441\u043b\u0435\u043d\u0438\u044e de vin.\n<\/p>\n

\nIndicatori cereale naturale blocajele de trafic au fost mai bune, \u00een medie, dar \u00eempr\u0103\u0219tia printre probe a fost semnificativ\u0103, plus c\u00e2teva \u0437\u0430\u0433\u0443\u0431\u043b\u0435\u043d\u043d\u044b\u0445 sticle, din cauza „\u043a\u043e\u0440\u043a\u043e\u0432\u043e\u0439 boal\u0103”.\n<\/p>\n

\nTehnice de plut\u0103 (e care \u0430\u0433\u043b\u043e\u043c\u0435\u0440\u0430\u0442\u043d\u044b\u0435 \u2013 adic\u0103 dintre presat de firimituri \u2013 dar, cu cadre fixe suprapuneri pe marginile de cca.\u043f\u0435\u0440\u0435\u0432.) s-au ar\u0103tat mai bine \u00een termeni de trecere de oxigen, cu mai drepte rezultatele \u0219i o capacitate bun\u0103 de a p\u0103stra prospe\u021bimea vinului. Dar „din plut\u0103 boala” se referea de asemenea, de\u0219i \u00eentr-o m\u0103sur\u0103 mai mic\u0103.\n<\/p>\n

<\/p>\n

\nCu \u0219urub, au fost lideri din punct de vedere a p\u0103stra prospe\u021bimea vinului nou, dar a ratat at\u00e2t de pu\u021bin oxigen, ceea ce \u00een aroma de vin au ap\u0103rut specifice pentru factor de nuan\u021be de cauciuc \u0219i \u0432\u044b\u0441\u0435\u0447\u0435\u043d\u043d\u043e\u0433\u043e cremene.\n<\/p>\n

\nTrebuie remarcat faptul c\u0103 pentru a elicoidale capacelor volumul \u043f\u0440\u043e\u043f\u0443\u0441\u043a\u0430\u0435\u043c\u043e\u0433\u043e de aer depinde de materialul utilizat cu ei de garnituri. Cele mai frecvente dou\u0103 de tipul lor, cu propriet\u0103\u021bi foarte diferite.\n<\/p>\n

\n\u00cen acest experiment a fost folosit de cel care cu \u043c\u0435\u0442\u0430\u043b\u043b\u0438\u0437\u0438\u0440\u043e\u0432\u0430\u043d\u043d\u044b\u043c de acoperire (de la st\u00e2nga la figura. de mai jos). Anume astfel se \u00eenchid aproape toate vinurile din Australia \u0219i Noua Zeeland\u0103. Ei pierd foarte pu\u021bin oxigen.\n<\/p>\n

\nAl doilea tip \u2013 cu polimer garnitur\u0103 Saranex (de produc\u021bie a companiei Dow Chemical) rateaz\u0103 mai pu\u021bin oxigen dec\u00e2t sintetice de plut\u0103, dar un pic mai mult dec\u00e2t \u00eentregi naturale.\n<\/p>\n

<\/p>\n

\nConcluzia acestui studiu este c\u0103 problemele de vinifica\u021bie nu se limiteaz\u0103 la etapa \u0431\u0443\u0442\u0438\u043b\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f. Volumul de penetrare sub dopul de aer influen\u021beaz\u0103 starea \u00eenchis de con\u021binut \u0219i, \u00een cele din urm\u0103 \u2013 pe gustul \u0219i aroma a ceea ce sunte\u021bi \u043d\u0430\u043b\u044c\u0435\u0442\u0435 \u00een pahar.\n<\/p>\n

\nNu se poate opri un timp de via\u021b\u0103 de vin, plas\u00e2ndu-l \u00een absolut etan\u0219 \u00eentr-un borcan. Vin \u00eentotdeauna continu\u0103 s\u0103 se schimbe dup\u0103 \u0431\u0443\u0442\u0438\u043b\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f, \u0219i de aceea este extrem de important de a alege tipul de plut\u0103, care va maximiza pentru a se potrivi stilului de vin \u0219i o rat\u0103 de termenul s\u0103u de consum.\n<\/p>\n

\nAst\u0103zi, de la aproximativ 18,3 miliarde de euro anual produse \u00een sticle de aproximativ 5,7 miliarde de euro se \u00eenchid alternative tipuri de blocaje de trafic. Vinificatorii acum s\u0103 acorde aten\u021bie problema de acces de oxigen \u00een sticle, influen\u021ba lui \u00een chimia vinului la \u0431\u0443\u0442\u0438\u043b\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u0438 \u0219i \u00een continuare de depozitare. Iar produc\u0103torii naturale blocajele de trafic, cu toate for\u021bele \u00eencearc\u0103 s\u0103 reduc\u0103 procentul de alterare a vinului „plut\u0103 a bolii”.<\/p>\n","protected":false},"excerpt":{"rendered":"
