is you have to know a lot about wine to be able to tell what you are picking
my best recommendation is find a local wine shop or even fancy grocery store and tell them you want to try natural wines and what your tastes are (red, white, sweeter, dry, acidic, heavy, light, fruity).
if you find stuff you like, you sort of build up a repertoire of knowledge that you can use to pick your own bottles for the future. like, I had never heard of Kermit Lynch before last fall. now I will check for almost anything he's imported, because all the Kermit Lynch wine I've tried fits my tastes.
