“The aroma of Sauvignon Blanc is so unique that it is “T impossible to confuse it with any y other varieties… It has been be n compar pared d with h that hat of vani anilla a and and mus uscat at, but but it is different, and di and cons nstitut utes the he singul ngular ar tas aste of Sauv auvigno gnon n Blanc Bl anc wi wine nes.” Mi Michel Ca Cazeaux-Ca Cazalet (1910), am ampelograp aphy by by Vi Viala an and Ve Vermorel SauvignonBlancExperience.com

What constitutes sauvignon flavor “typicité” ?

“A “Almost imperceptible in unfermented must, the aroma characteristic of Sau Sauvi vignon Blan anc wines mai ainly develops during al alcoholic fermentati tion from th the ar aroma-less p precursors i in th the m must. t.” Denis De nis Dubo Dubour urdie dieu in in TONG NG, N°1 1 (2009) 2009) “ It It i is t the w winemaking w which r reveals t the a aroma h hidden i in t the f fruit … … T The w wine tastes m more o of f fruits ts th than th the g grape d does … … F Fermentati tion a acts ts t to r reveal aroma aro a by libe berati rating ng the the aro aroma a compo pounds unds in n the the Sauv Sauvigno gnon n Blanc anc grape grape.” ” Emile Pe Em Peynaud, “The Taste of f Wine (1 (1980) SauvignonBlancExperience.com
