In order to determine the grain-size of tea, the sieve analysis of tea was examined with J. I. S. standard sieves. The test sieves used had openings of 500-5, 660μ in √2 magnifi-cation series. On measuring the grain-size distribution of tea, 50g. of tea were sieved for 5min. with Ro-Tap shaker, and the residue on each sieve was weighed.
