Check with Pappers - he's got a thread here about stovetop pasteurizing homebrew cider .... He can surely help you with some answers, I'd think.
Sounds like you're getting a sparkling wine .... If that's true, I'd bottle in champagne or cold duck bottles, and if that is true, I'd definitely
NOT use regular wine bottles
Just bottle some of it in a plastic (water?) bottle .... let it stay in a warm room for a couple of days, and see if the bottle gets hard - if it does, then it's carbonated! If it doesn't, no carbonation ....... Have you taken a hydrometer reading of it for a few days in a row? ... that should tell you if it's through fermenting .... but I'm not a wine-o, that's my wife! .... I'm just the beer-o of the house!
