Bobs Red Mill - Sweet Sorghum Flour Gluten-Free 22 oz

Is this a single bag or is it a 4 count box like the rest of the Bob's Red Mill that's similarly priced?

Is this a whole grain product, or does the "white" mean the bran and germ have been removed?

Is there a difference between sweet sorghum flour vs sorghum flour?

Can this flour be used to make homemade biscuits?
