This website was brought to my attention throughout the week: Appellation America.
I really like this website as it focuses on U.S. wines and giving different regions throughout the U.S. distinction. You can look up several regions throughout the various states, search for regional wines, and read wine reviews made by the Appellation America team! There's also some great "Featured Articles" on this page here!
It's a great way to acquaint yourself with U.S. wines. I really encourage you to check out the website and explore some of your great options.
