Sure, bottling with those plastic stoppers is easy. All you need are: the stoppers, the wire hoods, the champagne bottles of course, a rubber mallet & a small tool for twisting the wire hood. I think any HBS that carries champagne hoods will also carry the twisting tool. It's only about $5 & it really is required to tighten the wire hoods, and it's really easy to use.
Just fill your bottles as you usually would, then just tap the sanitized stoppers into the bottles with the rubber mallet, make certain they're all tapped in good. Once all the bottles have stoppers in them, start with the wire hoods. The tool is a steel hook in a wooden handle & it turns as you sort of crank it. It sounds more complicated than it is, it'll take you 1 or 2 tries to get it right & figure out how many turns to tighten without breaking the wire, for me 7 turns was perfect. Regards, GF.
