In my own opinion, you can't talk natural wines without talking about Catherine & Pierre Breton. La Dilettante is a more widely produced, and more easily found in the U.S.; it's also a more approachable wine. It's a wonderful introduction and such legacy too, however, keep in mind it's not their best offering.
Their famous poster (below) hangs in the doorway like a talisman at The Verre Vole, Mecca for natural wines. The image beckons you, welcomes you and tells you what you can expect and who -- so don't miss your chance. But, just know, when you do find La Dilettante, the journey has begun.
