As a native son I'd like to drink more local wine, but hardly any are to my taste, and those that are usually cost way more than similar imported wines. So I thought I'd start this topic for people with Euro-centric palates to share exceptions.
By "good value," for everyday drinking I rarely buy wines that list for more than $16 (though thanks to closeouts etc. my average everyday cost is more like $10). For special occasions, I'll spend much more, e.g. >$80 for good, mature Bordeaux.
Roederer Estate is my most recent exception. I always loved their wines but found them overpriced, but Champagne has gotten so expensive that RE is currently very competitive.
