Bottled my Irish Red 12 days ago. Final Gravity was stable and spot on. Filled 35x 12 oz bottles with crown caps and 5x 1 liter swing top bottles. After filling all my bottles, I realized that my first bottle was slightly underfilled (2-2.5 inches of headspace). I had no beer left in the bottling bucket to correct it so I just closed it up and put everything in boxes in a dark laundry room. 1 of the big swing top bottles cracked, the bottom fell out. The 12 oz bottles open and pour perfectly carbed.
Do you think some of my priming syrup stuck to the bottom of the bottling bucket for the first bottle?
Do you think it was too much headspace?
…Or should I prepare for more?
