Essence.
I say: Zuvan is the name that people give to two things. One of them is a grain similar to wheat. People make bread from it and say that zuvan is kanit. Others call by this name something intoxicating and nasty that comes across among the grains. This has nothing to do with what we are doing.
Choice.
The best zuvan has light leaves, not full of holes or crumbling, but on the contrary, sticky when chewed, reddish and slightly tart.
