there are lot's of framboise Lambics, most of the ones I've seen come in a 750 belgian bottle with a non-US standard cap diameter. I think you can get either a capper that handles that or even an adapter for whatever capper you have, then you have a great stash of heavy duty bottles for very high carbonation beers!
They probably also accept belgian style corks so you could also go that way, they make the plastic kind that you can push in (or bang in with a mallet) and wire down.
