I've only made one wine kit to date and I used wine bottles. However, I was listening to a Basic Brewing podcast recently where James was talking to a guy about wine kits. The wine guy said to not be uptight about it and just use the beer bottles. That's my plan going forward.
When you think about it, it makes sense. Wine isn't carbonated so there isn't really any issue with pressure. The only issue I would consider is the oxygen in your bottles, but maybe we should use oxygen absorbing caps. Really though, the Island Mist kits are made to drink quickly and not store so I think you would be fine with regular caps.
I'm bottling my first Island Mist in about a week and plan on using beer bottles.
