I bought a 14.7 gallon demijohn used. I used it one time, cleaned it out, and then noticed a hairline crack in the glass on the widest part of it running across it. Now I'm afraid to use it. I don't want to have it break with 14 gallons of wine in it and waste a huge amount of wine and/or make a huge mess. I really liked it, but no more of them for me. It was the kind in the plastic basket.
