Hi Ron, I am using the bags for the first time, keeping two strip loins at a friends house. As of Friday 12/5/14 we have had the meat aging for 1 week. My question/concern is that there seems to still be a considerable amount of blood still in the bag; we have good seals on both bags and they are in contact with the beef, but not “adhering” to the beef in a manner we thought would have been achieved by now. No considerable smells and have consistently opened the fridge to circulate air throughout. We did originally drain the package from the store, but did not wash the cuts prior to sealing with the Umai bags. Any feedback is greatly appreciated.
