What is chametz really?

In a previous article I listed the five grains that can become chametz: Wheat, barley, spelt, rye and oats.

Where does the list come from? It appears in the Talmud, Mishna Pesachim 2:5, which lists in Hebrew חיטים (chittim), שעורים (se’orim), כוסמין (kusmin), שיבולת שועל (shibbolet shu’al) and שיפון (shifon). The only certain translations that can be mapped to actual species of plants are the first two, chittim means wheat, and se’orim is barley.

The other three are unclear. Rashi translates kusmin as spelt, shibolet shu’al as oats and shifon as rye which gives the above list. But according to the research of Dr. Yehudah Felix as reported by Rabbi Dov Linzer in Are Oats Really one of the 5 Species of Grain?, he seems to have confused some things. Spelt makes the list, though as a candidate translation for shifon. The other two are probably another type of barley and emmer wheat. No rye and no oats.

So what do we do with this information? Do we change the list? And what are the consequences? Oats are the only one of the traditional five grains that does not contain gluten and people with gluten sensitivity rely on the opinion that one can fulfill the obligation to eat matza with matza made from oats. Have they been making invalid brachot? Conversely, if anybody ate emmer wheat on Pesach, is he punished with karet (cut off)?

We can get to a similar problem fron another angle. Scientifically speaking, what does "leaven" really mean? Rabbi Gidon Rothstein in his article A More Flexible Future Orthodoxy argues that maybe the sages just assumed what was common knowledge at the time, they took for granted that these five were the only grains to become leaven. Now we have a greater understanding of the processes behind leavening, for example we know that yeast is a crucial ingredient. If the list of five species is not tradition handed down from Sinai but the sages’ own interpretation, he argues that we might well include all leavening agents to the category of chametz.

While there are only slight chances that either scientific understanding of leavening processes or an identification of the exact species denoted by the Hebrew words in the Mishna will change the traditional list of grains that can become chametz, this is another fascinating instance where science and Tora collide.

Because I am very forgetful and English is not my native language, here the five grains:

If you are interested in botany: It is not so clear to which grains the mishna is actually referring, as the exact meaning of the Hebrew names has been lost over time. The Hebew is as follows: שיפון (shifon), כוסמין (kusmin), חיטים (chittim), שעורים (se’orim) and שיבולת שועל (shibbolet shu’al). Only wheat (chittim) and barley (se’orim) are definite. You can read more about this at the daily daf: Are Oats Really one of the 5 Species of Grain? – When Science and Halakha Collide.
