it must have a capacity of 380 ml and weigh 200 g (±20 g). If a small bowl is used, it must have a capacity of 200 ml and weigh 105 g (±20 g). If the test involves milk, then it is added to the bowl before pouring the infused tea into it, unless that is contrary to the organisation's normal practice. If milk is added after the pouring of tea, the standard notes that best results are obtained when the liquid is between 65 and 80 °C. 5 ml of milk for the large bowl, or 2.5 ml for the small bowl, is used. Pot and bowl An annex of the standard describes two alternative pots (310 ml and 150 ml) and corresponding bowls (380 ml and 200 ml) “which are in widespread use” for tea tasting, including engineering drawings of their cross sections. The type of pot described is also known as a taster's mug. Criticism The protocol has been criticized for omitting any mention of prewarming the pot. Ireland was the only country to object, and objected on technical grounds. Competing standards In 2003, the Royal Society of Chemistry published a press release entitled "How to make a Perfect Cup of Tea".
