Chardonnay is always white wine made from chardonnay grapes, but exactly where the grapes are grown, how the wine is made, how it's aged and what types of barrels are used in aging produces characteristics that can make one chardonnay taste very different from another. Those characteristics don't fall neatly into a "type" category, except whether it is "unoaked" (stainless steel barrels, no exposure to oak, cleaner, crisper flavor)
