I have just bottled some homebrew. some in clear cider bottles (strongbow) and the others are in green heinekin bottles. The strongbow bottles capped fine and left a ring on the top of the cap as they usually do. With the heinekin bottles the caps didnt leave the ring and are loose enough to spin and just pop.the off with my fingers..... are these the bottles? The caps? My capper? Anyone else have this problem?
