Full Bodied White
Full Bodied white is at it's simplest explanation, rich white wine. It can come in many different guises and styles, but ultimately, it's designed as white wine intended to be drank with food as the fullness helps counter many dishes.
Full bodied white wine is not always oaky and buttery, and while Rioja Blanco and some Aussie or South African whites can be this way, in the modern era it's actually not as common anymore. Many modern full bodied whites are actually very clean, viscous, velvety, ripe, and robust. Southern Italy and France have some lovely examples too, like Fiano and Viognier.
