What are the very largest wine stores in the Baltimore/DC area?
I'm based in Baltimore but travel regularly to DC. We're working our way through Andrea Robinson's "Great Wine Made Simple" - which is a great "learning about wine" book with a lot of tastings. I'm noticing that even at the very largest wine stores I know, while it's easy to find particular California Merlots, Chardonnays and Cabernets, it is usually impossible to find, let's say, a particular Sancerre or Chassagne-Montrachet or California Syrah or Kabinett Riesling - all of which are typical requests from this book.
As the wines get more obscure, it'd be nice to have an *absolutely huge* wine store where I could find more of them and have to order less. Failing that, one that carried a lot of non-US wines would be nice. Doesn't have to be that close by as we can drive somewhere once a month. Thanks!
