Ah. I see. You only added the priming sugar to the beer bottles. Missed that little detail. In the wine bottles, you might end up building some pressure if you did not stabilize - though that would be the case with or without the sediment which is likely mostly dead yeast cells or other precipitate. The yeast that could conceivably kickstart new fermentation might not be visible - for instance, introduced during the actual bottling. That said, if it has been sitting since September, I'm guessing its pretty dry and run it's course. If you stabilized, I'd say no need to worry. If not, there is a chance but, given the age, you're probably ok and very unlikely it will build rapidly. So, just keep an eye out for micro-movements on the corks. I wouldn't worry.
Thanks for the great reply, puts my my mind at ease now anyway. Truthfully I don’t think the wine bottles will last long enough to build considerable pressure even if they could haha.
