Well said Kevin. As a fellow Canlis sommelier I could not agree more with Gramercy being an easy sale. It is up to the sommelier or wine steward to sell these types of wines. It all about the approach you take to the guest. At times I personally enjoy a fat and extracted wine, they have there place. I call them "fireside wines". They are not to think about or have with food, just guzzle.
As far as manipulation goes. My big issue is the whole "mega grape" or some other additive to make wines more concentrated than they already are. Seems silly and basically cheating. I have surely tasted wines that seemed artificial. Kevin remember the Pinot we tasted recently? Interesting thread nonetheless.
BTW great info Greg. Thank You.
