just got 3 carboys (5 gal) from my father in law, as his deceased father was a hobbist winemaker.
They cleaned up well with straight-A...but I noticed on the exterior, on the bottom, are what appear to be circular cracks.
The bottoms are textured like most carboys, and taking a photo isn't doable (I have no camera good enough).
I can feel these crack lines with my fingernail, and they don't appear to go through all the way.
Each carboy held 2 gallons of cleanser without any leaks and the 3rd held 5 gal. no problem.
so, are these 'stress fractures' forming?
or are these normal due to the way these 30 year old carboys were manufactured?
I had to put off my mead making plans yesterday cuz I didn't want 5 gallons of fermenting must laying on the carpet.
