This woman, a sales assistant in a French wine shop, tells what a Parkized wine is like. New oak is apparently one of the characteristics.
It may be too simple to say that. Oak using is a technique adopted by all wine makers. There are a lot of options of oak using, New oak vs Old oak, seasoning or not, their combination, types of oak, time spent on new / old oak, etc.
Even the traditional wines are using new oak. Wine making has hundreds of years of history. In the old days only wooden vats were used for making wine.
New oak does impart certain flavours into wine but, as usually, overly oaked wine makes more harm than good.
My view on Parkerized wine is "overly concentration of fruit and extensive new oak ageing". The result is a hugh, big, burly wine with tons of fruit and strong oaky flavours. It lacks the elegence of a wine. Some Parkerized wines are so concentrated that it is like an unaged Port. The result is that the wine usually has stronger flavour then the food. French food emphasizes its delicacy, freshness so a parkerized wine may overpower it.
