Putting some flaked barley in a mash for a dry stout. I've never used it before and I note that it looks feels and tastes like a good old tough chewy horse food. I realise that it has been steamed and rolled and presumably gelatinised. However would it benefit from being boiled for a short time to rehydrate it and stir it into the mash, or will it melt in ok as is? I BIAB so stuck mashes etc aren't a problem.
