Joe,
Sense of place and rustic are both euphemisms (for me); loosely, rustic has to do with structure, mostly tannins and sense of place to do with aromas and flavors other than grape variety.
I also understand the narrow use of sense of place, eg., cranberry/rhubarb for Anderson Valley, Pinot.
But with these wines (so far) I sense no place elements - just very pure and accurate renditions of the variety.
I have, for a long time, thought that the highest and best use of wine grapes is their ability to reflect place. In making wine, I strive for that. But these wines are leading me to question the paradigm or, at least, enlarge it.
These wines are both accomplished and compelling but in a way that I had considered to be second tier - after tasting these, I think I was a bit too judgmental. These are really good.
Of course, this is a small sample and, being in the middle of CA wine country, I have likely been led to a somewhat less place-driven model. And who knows what getting older does to one's taste buds.
But everything else being equal, Sandlands has given me something to think about and some delicious wines to do it over.
Best, Jim
