Roots Run Deep

This morning, my husband and I were sitting down and doing more research for our as yet pie-in-the-sky vineyard and he came across a wine label that at first blush is really clever. The label called Educated Guess is from the Roots Run Deep Winery in Yountville, California. I have to confess that I know nothing about the winery. When I went over to my husband's computer to see the label, I said, "Oh, that's the flavylium cation of anthocyanin", and he concurred. I asked him to send the link to me and when I did a little more browsing of the site, there was more information on the label, including the following: For those of you who aren’t chemists and want to know more about what the 5 formula strings on the label mean, please download this PDF. So, I downloaded the PDF and found an error. For starters, sulfur dioxide, the explanatory PDF superscripted the 2, like this SO² instead of the correct chemical shorthand, SO₂. There are numerous other errors that appear on the label. How many do you see?

Here is the link to the explanatory PDF.
