Vicenzi Aperitivo

The Italian export version. Per the OU it, as well as many Italian domestic versions are certified. However, their website says they are only approved with the OU on the label. Do we have to worry that processing and ingredients for other batches may differ? Is this a question only the OU can answer?

I’m not sure if we’re going to be able to answer but we can try. Can you share a link to the product in question?
