I realize this could belabor the point. But, "sterile" means that you
are sure everything is dead. Period. No "degree of sterility," it is an
absolute.
Because we don't know exactly what organisms are in our wort, we cannot
say it is sterile unless we know that we have killed *everything* that
could be in there. Canners and commercial brewers do not claim to
maintain sterility, but only a high degree of sanitation, usually
through pasteurization. The TDT drops sharply with increased
temperature (autoclave 10 min, 121C). -bdl
