Your wine guy had some good picks but left out a great option: a medium-bodied German White such as Piesporter Michelsburg or, for for the adventurous, an Alsatian such as a Pinot Blanc. Neither need be a late harvest (Spatlese), you don’t want extra sweetness. $12-16 bucks should get you nice ones.
And add Chenin Blanc to the California list.
There are some fantastic Oregon Whites, such as King Estate Domaine Pinot Gris, well worth the $25. Don’t let the varietal name mislead you, that is a viscid, creamy wine with lots of succulent fruit flesh in it and with a nicely balanced mineral finish that is not too flinty. So easy to drink it is scary. That’s my #1 pick, that will be a memorable wine!
Happy Thanksgiving
