what division and confusion? what convoluted trail? the question has been answered. Sulfites occur naturally in wine and the addition of a minute amount to stop the fermentation of the wine is part of the wine making process. What is the problem?
First, not all wine have added sulfates.
Not by a long shot. The Church makes no mention of an exemption for adding sulfates in Canon Law, the GIRM, RS or any other routinely referenced document that I am aware of. (Did I miss it somewhere?) How did I personally find out that added sulfates are OK? (At least I believe they are OK?)
I found a bottle of sacramental wine at my parish. I went to the website of the winery and read their rationale. While they mention “Canon Law” they offer no reference (as there is none.) They do mention a reference to a very obscure private 1922 permission. It took Google’s best efforts to find mention of the 1922 permission (Zenit now has made mention of it and it’s easier to find.)
I have no evidence from the Catholic Church that this permission is still valid and/or if it ever even applied to the USA other than practical, de-facto evidence from the winery. Hey, the winery is selling and shipping sacramental wine based on the private 1922 permission. Then it must be OK?
You would think that the Church would very carefully specify what can and can not go into wine.
Why would the Church leave something this critical up to some very obscure private 1922 permission? As specified now, sulfates cannot be added unless someone wants to rely on the 1922 document.

"Mass Wine: Treated with Sulphurous Anhydride, Etc. (Holy Office) Private.
The Holy Office was asked by the Archbishop of Tarracona: Whether in the Sacrifice of the Mass, wine may be used which is made from the juice of the grape, treated with sulphurous anhydride or with potassium bisulphite.
Reply. In the affirmative.
