Coarse whole-leaf astringent tea contains an excess of stalk, stem and woody fibre. When making a brew from this, heaped up teaspoons are necessary. Ty.phoo however, is mainly leaf edge, from which as much as is possible of the cellulose portion of the leaf is excluded. Therefore, with Ty.phoo you only need to use level teaspoons. Ty.phoo is the most economical of all teas for ‘It goes just half as far again' as common coarse varieties.
