Washing for non-grain bread

Hi,

The enactment of hand-washing before bread is tied to bread made from material the Torah calls דגן. Bread made from other materials does not require hand-washing.

Traditionally, דגן is understood to include wheat, barley, rye, oats and spelt.

(Mishneh Berurah 158:7)

Have a great day,
Mordechai
