I agree with cooper, don't bottle it yet. The large air pocket you have is probably why you aren't seeing the bubbles. There isn't enough pressure to force them out as vigorously as you are used to seeing.
If you want to rack it, that's fine. Maybe even add some honey when you do for a little kick to your yeast. But it needs ferment for a good three months before bottling. And then age at least another 3. The champagne yeast is good for a more dry, higher alcohol wine, but it takes longer.
With my batches, I open the first one thanksgiving to note some of the early characteristics and then I wait until the following spring before I open the next. It takes a lot of willpower but it's worth the wait!
As an aside, a fun thing I do with the flower castings after I'm done boiling them is set them out and make sun tea.
