Some grapes are fairly easy to write about and some are much more difficult. At the moment, I have five different browser windows open with 20 tabs open between them as well as a handful of PDF files littering my taskbar. All of these windows are open because I was trying to find the answer to one single question: is Tintilla de Rota the same grape as Graciano? After several hours of digging and reading (and some money shelled out for access to specific articles), I think that I may have found an answer, but before I tell you what it is, I'm going to take you on the journey with me to give you a sense of how confusing this stuff can be, and how, despite the claims of many that this kind of technology will eventually rid us of a lot of unnecessary confusion, a lot of confusion still exists.
