Fruit, herb, and cider vinegars sold direct to Iowa customers
True vinegar naturally sits well below the pH 4.60 cottage food threshold, but Iowa's law still calls for each batch to be measured with a calibrated pH or water activity meter, especially once you start adding fruit, herbs, or other ingredients that could shift the balance.
Add your contact info, the common name, full ingredients, the processing/canning date, and the exemption statement to every bottle.
Sell only direct-to-consumer, and keep your batch testing records on hand in case a regulator or buyer asks to see them.

Even though straight vinegar is reliably acidic, Iowa's cottage food statute calls for documented batch testing across home-canned and acidified goods broadly — it's a quick, cheap step that protects both your compliance and your customers once you start blending in other ingredients.
You can, but adding low-acid fresh ingredients can shift the finished pH upward, so test the actual finished infused product rather than assuming the base vinegar's acidity carries through unchanged.
A shrub is a vinegar-based fruit syrup often mixed with soda water by the end customer; sold as the shelf-stable syrup itself, it generally fits the cottage food/preserves-style path rather than the stricter Beverages rules that apply to ready-to-drink perishable drinks.
Yes — Iowa's cottage food labeling rule for home-processed and home-canned goods calls for the processing date on the container, in addition to the standard label elements.
