Probably just you. Bottle size rules were pretty clearly specified. In fact, it's the first bullet under "How to Enter This Competition"
"1. What kind of bottle is required?
Beer, mead and cider entries must be in sealed, food-safe containers that meet these criteria:
Hold a minimum of 10 ounces (296 ml) in volume.
No more than 2.75 inches (7 cm) in diameter and no more than 9 inches (23 cm) in height, to ensure that they will fit in standard longneck case box slot.
Must be free of ink, paint, or paper labeling other than the competition entry label. Obliterate any lettering or graphics on the cap with a permanent black marker.
Bottles not meeting the above requirements will be disqualified."
Refund policy is also pretty clear:
"Refund Policy: Refunds will be issued on an extremely limited, case-by-case basis, upon request and pending review by the AHA. Refunds will be authorized only for prohibitively extenuating circumstances that prevent paid entries from being submitted, and only in the event that the refund request is received prior to February 23, 2016. No refunds will be given after February 23, 2016. Contact the AHA National Homebrew Competition Director, Janis Gross, before February 23, 2016 to request a refund."
