\nU\u017e ste niekedy ochutnali such\u00e9 biele v\u00edno, ktor\u00e9 sa zdalo, \u017ee sladkej chuti, aj napriek uistenia vin\u00e1rov je, \u017ee je \u00faplne such\u00e9. A nie Si s\u00e1m, v tomto. Tento jav m\u00e1 dlh\u00e9 n\u00faten\u00e9 degust\u00e1torov hodi\u0165 do obo\u010dia v prekvapi\u0165 a pochybnos\u0165 o ich vlastn\u00e9 pocity, \u017ee sa zdalo, \u017ee je v rozpore s faktami.\n<\/p>\n

\n „N\u00e1pad sladkos\u0165 bez cukru sa zd\u00e1 paradoxn\u00e9,“ hovor\u00ed Axel Marchal z Univerzity v Bordeaux. Na konci nulu za\u010dal \u0161t\u00fadium, v ktorom tento probl\u00e9m bol hlavn\u00fd.<\/p>\n

\nExistuje presved\u010denie, \u017ee etanolu a glycerolu sp\u00f4sobi\u0165 pocit sladkosti v such\u00e9 v\u00edno, ale v\u00fdskumu, vr\u00e1tane prebiehaj\u00facich V\u0161ak nedal d\u00f4kaz tohto tvrdenia. Uk\u00e1zalo sa, \u017ee dubov\u00fdch sudoch ma\u0165 ove\u013ea v\u00e4\u010d\u0161\u00ed vplyv na chuti poh\u00e1r Chardonnay.\n<\/p>\n

\n„Na\u0161li sme cel\u00e1 rodina l\u00e1tok, ktor\u00e9 predt\u00fdm nevenoval ve\u013ek\u00fa pozornos\u0165. S\u00fa zadarmo dosta\u0165 do v\u00edno z dreva sudy a da\u0165 zmysel sladkos\u0165 v nepr\u00edtomnosti cukrov. Z\u00e1rove\u0148 s\u00fa 8,000-kr\u00e1t slad\u0161\u00ed ako sachar\u00f3za“.<\/p>\n

\nBez myslenia, v\u00fdskumn\u00edci im dal \u013eahko zapam\u00e4ta\u0165 meno circuitterminating (z lat. Quercus, dub).
\n\u010eal\u0161\u00ed krok Marsala, v spolupr\u00e1ci s renomovanou vin\u00e1ra Denis dyuborde (Denis Dubourdieu), bolo spolo\u010dn\u00e9 publik\u00e1cie \u0161t\u00fadie ukazuj\u00fa z\u00e1vislos\u0165 stupe\u0148 sladkosti vozov\u00e9 o strom vina od typu dub, z ktorej hlave\u0148 je vyroben\u00e1.\n<\/p>\n

\n „Bolo mi jasn\u00e9, \u017ee sessile oak obsahuje podstatne viac o t\u00fdchto sladk\u00e9 zl\u00fa\u010deniny ako dub, tak\u017ee viac vhodn\u00e9 na \u00fa\u010dely v\u00fdroby v\u00edna,“ hovor\u00ed Marchal. <\/p>\n

\nSessile oak (lat. Quercus petraea) je p\u00f4vodom z Eur\u00f3py druhov biely dub rastie na plytk\u00fdch kamenist\u00fdch p\u00f4dach, ktor\u00e9 dal mu n\u00e1zov: petraea znamen\u00e1 „skalnat\u00e9 p\u00f4dy“. Jej drevo sa pou\u017e\u00edva v stavebn\u00edctve, v\u00fdroba a sudov. Ale pedunculate oak (Quercus robur), rad\u0161ej pracovn\u00edci Kabinetu tvorcov.\n<\/p>\n

\nD\u00e1vaj\u00fa n\u00e1m tieto vedeck\u00e9 v\u00fdpo\u010dty?\n<\/p>\n

\nV\u00fdvoj met\u00f3d pre identifik\u00e1ciu drev\u00edn, po\u017ei\u010diavanie viac sladkos\u0165 such\u00e9 v\u00edno, prida\u0165 \u010fal\u0161\u00ed d\u00f4le\u017eit\u00fd n\u00e1stroj v vin\u00e1rov Arsenal. Teraz si bude vy\u017eadova\u0165 ur\u010dit\u00fd materi\u00e1l nie je z lesov, ale od typu dub.\n<\/p>\n

\nAle nie pr\u00edli\u0161 hlboko sme sa dostali do vedy, a nie strati\u0165 romantika okolo narodenia v\u00edna? P\u00e1n Marchal sa domnieva, \u017ee je: „veda v\u00edna d\u00e1va n\u00e1m slobodu tvorivosti.“<\/p>\n","protected":false},"excerpt":{"rendered":"
