This is the primary reason most recipes recommend you add sulfites every time you rack because - by the time most of us get around to racking a wine (say, it's every month) - it's time to add some more sulfur dioxide anyway. (winemakermag.com)
These are good at-home sulfur-assaying kits that you can use to measure the amount of sulfites in your wine. (winemakermag.com)
For instance, in Sauvignon Blanc, greater sulfite additions will favor the presence of thiols, sulfur-based compounds that provide aromas like grapefruit and passion fruit, especially if the wines are vinified using a reductive approach-such as in stainless steel tanks, with very limited contact with oxygen. (sevenfifty.com)

In truth, it would be extremely rare to find a wine produced and bottled without sulfites. (firstcrushwinery.com)
So in reality, no wine can ever be "sulfite free," because of this natural occurrence within the grape itself. (firstcrushwinery.com)
In regard to modern winemaking , the natural amount of sulfite contained in the grape is not at all sufficient to protect the wine during the winemaking process or to insure the long-term quality of the product for commercial consumption. (firstcrushwinery.com)
At specific subsequent stages in the wine making process carefully calculated amounts of sulfite are added for the same reasons. (firstcrushwinery.com)
