its all a bit fishy

It's explained here: Fish, Milk, Eggs and Nuts in Wine?

Of course I had to check the label of our favorite (cheap) wine. Doesn't say anything about any of that. I imagine they just didn't put it on the label. They have to use something. At $13 a bottle retail I can't imagine natural settling would be cost effective.

That statement seems to be an Australian & NZ requirement. In the EU, after July, 2012, wine labels must disclose use of milk and/or egg.

In the US, you cannot just slap on any old label. The complete label, exactly as it will be printed, including artwork, must be approved by the Feds. Allergen warnings aren't required, however, the label must indicate if there are sulfites in the wine, because according to the US FDA, "approximately 1% of the population has some sensitivity to sulfur compounds and sulfites and about 5% of asthma sufferers can have adverse sulfite reactions. Asthmatics who depend on corticosteroids are especially prone to sulfite sensitivity and can have severe reactions " There also must be a warning about potential health issues about consuming alcohol.

Hong Kong and South Africa, In Canada, allergen labeling is voluntary. A number of other countries require disclosure of sulfites. EU will require that in 2021, as well.

One problem for winemakers is that they may have already ordered the labels before final decisions are made about fining a particular wine. So they put the warning on the label, just in case. The final wine will bear the warning, even if none of the allergens were used. For that reason, proposals to require the warnings have been controversial in the US.

When I worked for a wine company we had to get labels approved to be able to sell wine. I'm kind of surprised that labels with allergens are not required in the US, considering how we tend to be about everything else. I mean, when a jar of peanuts has to have a warning on it that it may contain peanuts...

In 2006, the BATF proposed such a rule. Didn't fly due to winemaker objections.

The whole idea of finings is that they will be left behind and not get into the finished product. I really wonder if anyone has ever found enough milk or egg or isinglass in a bottle of wine to cause an allergic reaction in even the most sensitive person.

And I wonder if someone with a sensitivity to tannin wouldn't be just as sensitive to grape tannins as to chestnut or walnut tannins. And I wonder if there are enough of any other element found in nuts along with the tannin to produce an allergic reaction in anyone sensitive to that element. It seems unlikely -- if tannin is what the winemaker wants, she'd want to avoid anything that added any other flavor.
