I have gone 60days the older the brisket the betterIf it's cryovac'd, I've heard of folks letting it go for a month past that sell by date. I'm kinda leary, and use or freeze by that date on the package. I have also bought briskets with out a date on the label! :eek:

For Competition i like mine at least 30 days old I have aged them 60 days before with a thick layer of sea saltAs long as it's in the ORIGINAL cryovac, then you can let it go for several days, some guys go a month or more.
It's called wet ageing & does tenderize the meat & change the flavor.
