Quite simply, unwooded Chard or "unoaked" is wine that has never seen the inside of an oak barrel. Typically it will be wine that is fermented in a stainless tank, as opposed
…to a wooden (oak) cask/barrel. The oak typically helps to balance the tannins, among other things, and gives wine that "full mouth" feel with lots of mid-palate tastes. Unoaked wines are great for people who claim to have an "allergy" to wine. It is the tannins that people typically react to, and those come from both the skins and stems of the grapes, but also from the oak barrels. If you don't "oak" a wine, the you have a lower tannin level which should make the wine bearable to drink for the aforementioned crowd. (MORE)
