If it hasn't changed in 11 days, then it's probably not going to.
The sulfur smell is a nutrient deficiency thing, usually in combination with somewhat warm fermentation temps. Some batches of juice have better nutrient contents, plus it's much less of a problem fermenting cool. So the lack of that smell is probably more due to the temperature, and really that's a good thing. Your apfelwein will probably be fantastic, lower temps also mean fewer fusel alcohols.
You know, I really think you have pectin haze. Pectin is a water soluble carbohydrate, so it very well could be contributing to the gravity reading without actually being fermentable. About 3/4 of the commercial juice on the market is cleared by treating the juice with pectin enzyme. That last quarter is cleared by running the juice through a centrifuge to remove the particulates. That process removed the particulates and clears the juice, but it leave the actual pectin intact. So, if you ferment it, you get particulates stuck in it again. You will also get gravity readings that are a little high as some of what you are measuring is non-fermentable carbohydrate.
If it was mine and I wanted it dry, I'd mix a little pectin enzyme in and sprinkle a packet of champagne on top. Be careful if you decide to do that, you could end up with an apfelwein geyser from the dissolved co2...That reminds me, it wouldn't hurt to degass it. It's much more common to do that in mead, but reducing the dissolved co2 might get things going again too.
I used Tree-top just as the OP said, but on the label it did show a something like 31g of Carbs and 28g of sugar, so maybe that's the issue?
I'll try these suggestions. I actually have a drill mounted degassing wand because we just made a wine kit.
Edit: I just went ahead and degassed it. I got quite a geyser, but I think I got most of the CO2 out. I'll go grab some pectic enzyme and yeast when the LHBS is open later, any idea how much enzyme I should use, and should I wait a few days to do this now that I have degassed??
Also, will the champagne yeast change the taste of the final product?
