Finger Lakes - very well aquainted with the wines in that region. My wife and I made a "study" of them every time we dropped our daughter off at school, or picked her up from RIT.
Here's my recommendations for better vineyards in the area:
Keuka Lake
- Ravines
- McGregor
Seneca Lake
- Atwater (but you already know that I see)
- Ravines (yes, they are on both lakes)
The "best" wines in the region are their whites. The red's just don't have a full enough season to mellow down a bit, and as a result tend to be bitey and tannic, which age doesn't change very much. However, there is a vast taste difference from winery to winery even for the same wine style (dry reislings, semi-dry reislings, gewruztraminer, etc.) with the dryer offerings being more complex than their sweeter cousins.
But then, that's the fun of it ... going from winery to winery and just enjoying the day, and the wines, and the views (it is just so damn beautiful on those lakes on a sunny day). Have a great trip.
