Surely, someone has used them before. I see the IBC totes tucked awayat about every winery I've been to. It seems a person could keep wine in the totes or barrelsclose to8 months (I'm guessing) before the wine needs to be bottled or moved to something more inert. I realize that Flextanks are HDPE engineered to theoptimal thickness. Seems another container made from the same material would do semi-close job.
