can you cork champagne bottles?

[dmrevis]

I'm wanting to try elderflower champagne in the summer and as i cant get flip-top bottles i've saved a few cava style bottles. Is it possible to cork these, and if so where might i find a suitable corker and corks?

Please be very careful to ensure that your wine has stopped fermenting and that you measure your primings carefully when using Cava bottles. They are not as strong as "real" champagne bottles
