The idea of natural wines is a tricky subject. Mainly because the term really doesn’t mean anything specific. In general though, it means a wine that’s been as un-touched by a winemaker’s technology and techniques as possible. So what’s that mean? Things like chemicals in the vineyard (e.g. pesticides, or chemicals that keep the grapes from rotting or molding), or sulphur in the winemaking process. Sulphur sounds bad, but really it’s totally fine. It’s typically used very sparingly, and it keeps the wine from spoiling, so it’s essential.
So now we get the push for “natural” wines, which certainly comes from a good place and is something that I generally agree with. But in reality, there is NO way to know what is “natural” and what isn’t, or where in the spectrum of “natural” a wine may fall. It ends up being a little silly to my mind. The easiest way is to get to know a winery that you like a lot, and learn the winemaker’s philosophy. Easier said than done, yes. Your best bet is to find a great wineshop and talk to the folks who work there. They’ve often visited the places themselves.
