I have seen this question asked many times, Brisket is different than Ribeye's or Strip's So I wrote to Texas A&M who study this and here is their reply. Since they only addressed the tenderness issue I will write back and ask about flavor,
Gary, this is a question we are getting more often and do not have a good answer for. We do not know if aging really helps briskets like it does ribeyes and strips. Because aging doesn't really help with connective tissue tenderness, the main problem with briskets, we do not think that aging briskets does much for briskets used in barbecue. I would recommend that you leave it in the vacuum package and keep in in the refrigerator for about a week before you use it. Keep tuned as we will probably start doing some research in the area in the spring.

Hello, I have a question. I smoke quite a few briskets, I usually buy at Sam’s in Cryovac Can I age the brisket in my refrigerator if I leave it unopened in the package? If so for how long for the best flavor and tenderness?
