I would say as long as they keep the air out then by all means go for it. And you can always store them in the frig. to drink first.
I enjoy reading your posts with interest about the different DB's your making and you sure got it going.
A friend gave me about 6-7 cases of those bottles. I thought I was in heaven until I realized the wine doesn't age/mature well (or at all, for that matter) in them. The condition of your wine at bottling will likely be the same as it will be in 6 months or 3 years. I continue to use the bottles but I cork them for storage. I use the flip top for leftover wine.
I have been using swing tops for Skeeter Pee for years. They work great! Ideal for picnics, Boating , etc. had the SP in them at least 6 months with no issues. Roy
I used them for a few wines, but noticed an off flavor. I got it in my head it was the rubber gasket, but I can't confirm that (it was pretty early on in my wine making so could've just been me making bad wine). Like Roger I still use the bottles, but cork them.
Make sure you use the appropriate size cork, but they work great. We usually use a few of them each batch, so we have smaller containers to sample and enjoy the first year or so.
The swing tops worked great! We used a couple of them and drank then first but even kept the wine fresh for two days or so u till we finished the bottle.
