Hōjicha products are reprocessed teas.  Because tea producers roast Sencha or Bancha or Kukicha to make this tea, it results in brown-colored leaves and  produces a brown-colored beverage.  In addition, the roasting process makes most caffeine sublimated.  And Hōjicha has less catechins, amino acids, and vitamin C than Sencha.  Therefore, if you are concerned about caffeine, we recommend you to try this tea.  And please enjoy its savory and roasted aroma and taste.  Also, please brew in a shorter time with boiling water, because boiling water helps to enhance savory aroma.  And you can enjoy Hōjicha with a larger thick teapot and teacup.  And be careful not to burn your tongue!
