Rather Simple Question ; Im bottling 5 gallons of Wild ale, going to transfer to bottling bucket, add my priming sugars for carb, and transfer half the beer to 24 bottles give or take. The remainder im going to blend with wine. I know commercial wine usually has no active yeast left over. My question is if im adding all this wine, will the process in which I am doing this and the amount of sugar be enough to properly carb the blended bottles?
Maybe not so simple. Depending on what "wild" things are in your ale, they may find some fermentables in the wine that the wine yeast did not finish off. So it might kick off a secondary fermentation. For this reason, I would blend and condition in bulk to make certain that you have a stable solution for bottling/carbonating. Once you are satisfied that you are good to go, then add priming sugar based on temperature and volume as normal. Strong wild cultures will be persistent for a long time, but you could add yeast at bottling, too, if you have concerns.
If I bottle half the beer and leave half the carboy with empty air space and the blended beer will also pose problems.. Do I risk leaving the headspace or say I'm just going to blend all the beer.. (I wanted to have both the base and blended beers in bottle) but if that's not possible I guess I can forgo that.
You can get a 3 gallon carboy if the head space really concerns you. I have used 1 gallon glass jugs (from apple juice) with a drilled stopper and airlock, too. If you didn't want to buy more stuff, though, I think as long as you seal it back up and keep your airlock full, the amount of o2 that would get in there shouldn't cause a problem, unless you fear you are already borderline with getting too acidic (and in which case you probably wouldn't really want to blend your ale with wine at all).
One other fly in the ointment is that sulfites in the wine may inhibit carbonation (just speculation since I've never done this).
You can always put a layer of CO2 down on top (heavier than air), or if you happen to have Nitro/BeerGas handy...
