Is this still ok to use? I don't have another empty carboy. I would like to rack one more time to get off sediment before bottling. The wine is 9 months old and totally degassed. The crack is on the inside and doesn't go through the carboy. The center is about 1 mm and these are 3 small cracks that are about 1.5 mm long. I just got this carboy out of storage, so I haven't used it in a while. Thoughts?
