I don't know if AHA provides the cups for all the first round judging sites or if each site buys their own. I judged in Portland and every beer I judged had poor head retention. Everyone around seemed to agree it was probably the cups causing the issue.
I received my scoresheets and on almost every one was "poor head retention". I can't really complain about it since everyone's scores should have reflected this problem.
I didn't note the brand/type of cups other than they were compostable. Does anyone know the type of cups used so I can avoid them for our future competitions/tastings?
