Sulfite-free does exist

[TimP]

I have seen some misinformation regarding sulfites in wine, and I have to correct them. I am the production manager at a winery in Missouri that produces sulfite-free wines. Yes, it is possible. We send our wines to an independent lab for testing and, using those results, have been given permission by the government (TTB) to state on our labels "Contains no detectable sulfites." These wines contain 0 (zero) ppm of sulfites.
Adding no sulfites really opens up the range of impressions, especially in our Cab Franc. Sulfites mute flavors and aromas.
I do not want to make this an advertisement, but a search for "sulfite-free wines" in Missouri will probably lead those interested to us.
