I am new to the winemaking gig, and just completed my first batch. After corking, I left the bottles sit vertically for 3 days before laying them down. About 6 hours later, I noticed that several of the bottles were already leaking (about 7 out of the 28 bottles). However, the corks were leaking from the CENTER, not around the edges where I would expect the cork to leak. It was as if the cork was bleeding; on the middle of the corks were anywhere from 1 to 6 beads of wine, almost as if someone took a syringe and stuck it through the cork into the wine.
I had someone suggest that it could be over carbonation in the bottles, pushing the wine through the corks. However, not all bottles are doing this.
Did I get some crappy corks? What the heck is causing this?
