L4Key, perhaps you are expecting your white too cold! Although there is much debate, a full bodied white should be served around 15°C (60F) and a crisp white around 10°C (50F). Most people at home drink their white straight out of the fridge (at 4°C) which means you lose most of the flavours.
(And most people drink their red's too warm, at room temperature, while it would be better to aim for around 15-18° depending on the type of course).
