Old Man: Actually, none of the five grains are Muskam to everyone. There are opinions that Chitah is a slightly different strand of most wheat that we buy. (When i researched this I wrote a “Purim Torah” article about how there is nothing on Earth you can eat because everything is a Safek B’racha in one way or another.) The generally accepted five grains are wheat, barley, oats, rye, and spelt. There are Ta’anas and arguments about each of them but you can’t go wrong holding by those five.
