Wine Purification: The New Gluten Free?

While in Atlanta over Christmas visiting some family, I went to my cousin's house for dinner. He opened up a bottle of red wine and I prepared to politely decline as I had noticed that in recent years red wine had seemed to make me feel sick. I didn't have any known allergies but my symptoms were all the same ones described as a result of ingesting sulfites. However, before I could turn him down, he brought out a Ullo Wine Purifier [1] and began to pour the wine through it. After he explained that this was intended to filter out the sulfites, I tentatively accepted a glass. After drinking a glass of this "purified" wine I can say that heuristically I didn't feel as bad as I typically do. But was what I experienced a placebo effect or was there really something to this wine purification?

As far back as 1986, sulfites have been recognized in the US as a known allergen, albeit a naturally occurring one in wine. [2] There is controversy over this and theories exist that suggest it is actually higher levels of histamine in red wine that causes headaches rather than sulfites. In any event, the idea that red wine can cause headaches and/or nausea is a widely recognized phenomena, even if it is over-reported. But if it is all a placebo effect, is there still a market for a "cure"? In the same way that gluten-free bread and pasta has become mainstreamed beyond those suffering from Celiac disease, so too could sulfite reducing solutions. Indeed, a number of products have emerged to address this problem. The Ullo Wine Purifier that I mentioned earlier sells filters at a cost of $2 per bottle while another company called Just The Wine sells a liquid that oxidizes the sulfites at a price point of only $1 per bottle. [3] And it seems to be working, at least from a market perspective. Ullo has gotten a number of good reviews, including one as recently as November 2019 in Food and Wine. [4]  Now, this improvement of the wines could simply be the aeration of and removal of sediment from the wine. But if it helps people feel confident drinking red wine again (even if it is a placebo effect), why stop it?
