I wouldn't doubt that, I've worked in businesses that have made me fully confident in my 31 year old man-child self, that I could successfully run a multi billion dollar corporation if those dummies could run a small business. =P
As far as concentrates, you also have to take into account what ingredients are used, and the batch you have received. batches can vary in age before they are received, natural flavors play a huge part in that as well, since no two batches can be exact because there are no two exact oranges. Sometimes we receive two batches that are slightly different in color, which is normal, but you have to compare it to the MSDS/SDS sheets that are generally available online, and they will show a color range for that particular flavor, i.e berry flavor says "color range: clear to slightly cloudy", and within that range is acceptable according to the paperwork provided with that flavoring.
so we have QC who double check everything to make sure it adds up. We once received a bottle of a flavor that is normally clear, and it looked like squid ink. We obviously refused to sell it, but things like that happen on occasion.
