Yes! Red wine benefits the most from the long, oxygenated aging process that comes with oak barrels. White wines generally require less aging, and because they have no tannins (which come from the red grape skins), they don’t require oxygenation. Stainless steel casks allow the wine to ferment and stabilize without the cost of an oak barrel. But some whites, notably Chardonnay, are also aged in oak to create their unique flavours.
