Wow, thanks Joe! I just happen to have a Sangiovese kit in my root cellar, and this is great info. Some Q's though:
First, my kit comes with both oak and tannin. Is what you suggest adding with the raisins in addition to what came in the kit?
Second, the nitrogen topper sounds like a great idea. I know I can Google this but hey, it's easier just to ask you: How do you find nitrogen gas in a delivery system to add to carboys?
Third, In the procedure Here is a picture of the powdered oak and raisons at the bottom of our carboy. To me that picture looks dry, as if you placed these ingredients into the carboy before racking the wine on top of it? Could you please elaborate?
Also great info on the view of the wine in the glass, but I cannot find the pictures. And thanks for the info on the Ferrari bottle filler--it looks like the answer to my prayers!
Last but not least, thank you for sharing your experiments and expertise!
