The Wild Ferment Chardonnay features the use of a natural or "wild yeast" ferment for all batches of juice, where the juice is encouraged to ferment with the indigenous yeasts present on the grape skins from the vineyard. The many individual yeasts each participate in some way to build layers of complexity and finesse into the wine. Further palate structure is built through extended lees contact and regular lees stirring. The fine-grained French barriques have also contributed an additional lift, fragrance and finesse to the wine.

Yalumba Eden Valley Wild Ferment Chardonnay 2006 is pale golden straw in color with a bright rim. Creamy almond nougat and toasted cashew aromas are threaded with bright citrus peel and white nectarines. The palate is brimming with creamy stone-fruit flavors with a crisp lemony brightness, fine toasty oak nuances and a refreshing finish.
