Can anyone tell the difference in flaked grains by appearance only? I got flaked barley from two different places. It turned out that I didnt need it all, so I have a sealed bag that Id rather not open until needed. The light colored one on top is from the original batch. The one below is noticeably darker and looks more like flaked rye than flaked barley. Unfortunately, the brew store shipped it out without marking the bag, so it makes me a little suspicious. Have you seen flaked barley this dark?
