I'm fascinated by the interesting conversation on TDS effect on SG on this thread. I ran the FW Super Tuscan /w 2 skin packs and RJS EP Super Tuscan side-by-side under similar conditions for comparison under 2 month EM. Both are now racked and have some data points to share : the SG / FG for the FW kit were 1.092 / 0.996 and for the RJS EP kit were 1.102 / 0.992. I believe the difference between the two comes down to the jammy skin pack in the RJS kit adding additional sugar that was missing in the FW skin packs resulting in lower alcohol concentration in the fermentated juice. The lower alcohol concentration will result in a higher FG in the FW kit.
Yes, the FW kit did ferment at a much faster rate (both used similar RC212 yeast starters), and another observation - degassing in 6 gallon carboys with the AIO degasser produced MUCH more CO2 evolution in the FW compared with the RJS kit - still trying to figure that one out (I had to break the vacuum multiple times otherwise it would have overflowed into the vacuum line, which I haven't seen before). I also have slightly more volume with the RJS kit after racking (leaving little liquid in the primary with both). Too early to compare the wines - they are now both dosed with cellaring tannins and too young. The FW kit did taste a little more lacking in body from the sip I had, but I wouldn't read too much into that at this stage.
I have an RJS EP Syrah that just received its second (5 month) racking and sneaked a sip - it's still way too young, but has wonderful varietal character and body. I therefore just ordered the FW Syrah /w double skins before the price increase ($114 shipped to CA) and will be running as a second comparison.
