It is also called "mugikogashi" in Kanto and "hattai" in Kansai. A version with powdered shiso, Japanese pepper, or dried citrus peel is called "kōsen". It is mixed with sugar and dissolved in hot or cold water, and is also used in confectionery.

Reading the bitterness

Mugikogashi is barley roasted and scorched, then ground into flour with a stone mill. The Britannica International Encyclopedia's explanation also defines it as barley and naked barley roasted and ground into powder. The same explanation lists a fragrant roasted aroma as a characteristic.

「香煎」 (in translation: "kōsen") is this kogashi with powdered shiso, sansho, or mandarin orange peel added. Several dictionaries define this relationship. The dictionary entries checked explain how mugikogashi and kōsen are made and their fragrant aroma, but do not state whether or how strongly they are bitter.
