I just returned from break and was eager to check my bottles. I gave two away over christmas so I only have two left with beer. The blue jug style had spots of sticky dried beer all over the side, so I figured it had either broken somewhere or had been leaking out of the top from not being tight enough. However when I opened the top it made a very loud pop and this is what I got,
I was pretty startled because I had thought that it had lost any carbonation. You can see all the little sticky spots in the picture, my best guess is that the inside didn't get completely glazed and the beer made its way through the porous clay wall to the outside, because there are tiny little chip like spots where the sticky beer was. Anyways I found it to be quite strange.
The second bottle I have still looks perfectly fine and I will get some more photos whenever I open it, probably sometime this next week.
