from GrogTag:

The beauty of mixing wine and technology is that it makes wine season almost non-existent.  From juice to frozen grapes, fruit wine to concentrate – you can make pretty good wine year-round these days, and that can only be a good thing.  Well, sometimes it can, anyway.  Our wine never seems to be good for more than vinegar barrel fodder, or drinking after all the good wine is gone.  But at least it looks good – and your bad wine can look good, too, with some cool GrogTags!
