What is Wheat?

What is Wheat?

Submitted by dobie on November 13, 2015 – 4:09pm.

Are all grasses essentially Wheat?

Are barley, rye, kamut and spelt all grasses (I suppose they must be), and are therefore Wheat?

Is rice a grass, and if so, is it a Wheat?

Are there any other usefull (to human nutrition and  thus, baking) grasses or Wheats not mentioned?

Thanks in advance,
