I have used plastic jugs in the past as well as some of the fancier glass jars but to be cost effective, I was thinking of using the mason jars. I have heard of people getting mold into the jars in the past. I would assume that if i boil the jars before using them to sterilize them and then bottle at 185-190 I should not have any problems. Any suggestions out there? Thanks and have a great end of the season. Kevin
