I wouldn't try in a wine bottle but the champagne bottles should be thick enough.
Indeed champagne bottles are quite thick and can hold a lot of fizz. Ordinary wine bottles are much thinner and should not be used for carbonating kombucha (or any other carbonated drink). A further advantage of champagne bottles is that you can easily cap them with a crown cap (just like the champagne producers do!). Although you don't easily get bottle bombs this way, you might still get a gusher...
