    "content_text": "Corn tea \u2014 oksusu-cha in Korean \u2014 is roasted corn kernels brewed in hot water. It is caffeine-free, naturally sweet, and tastes exactly as you would hope: toasted corn, a little like popcorn, with a rounded, comforting body. In Korea it is drunk hot in winter and cold from the fridge in summer, often instead of water.\r\nIt is one of the easiest infusions to like, and a good one for children and anyone avoiding caffeine.\r\nThree things people confuse\r\n\r\n\r\n\r\nName\r\nWhat is in it\r\nCaffeine\r\n\r\n\r\n\r\n\r\nCorn tea (oksusu-cha)\r\nRoasted corn kernels\r\nNone\r\n\r\n\r\nCorn silk tea (oksusu suyeom-cha)\r\nThe silky threads from the cob, often blended with roasted corn\r\nNone\r\n\r\n\r\n\"Popcorn tea\"\r\nGenmaicha: green tea with toasted rice\r\nYes\r\n\r\n\r\n\r\nCorn silk is a different part of the plant with a milder, grassier taste, and it is usually sold blended rather than alone \u2014 many \"corn silk\" products contain mostly roasted corn, sometimes with other ingredients, so read the list.\r\nHow to brew it\r\n\r\nBags: most Korean packs are made for a jug. One bag per 1 to 1.5 litres of boiling water, steeped 5 minutes, is typical \u2014 check the pack rather than using one per mug.\r\nLoose roasted kernels: 20g per litre, simmered for 5 minutes or steeped for 10.\r\nCold: brew, cool, and keep covered in the fridge for up to two days. Chilled corn tea is excellent.\r\nBlended: corn and barley together is the classic Korean jug; corn softens barley's edge.\r\n\r\nIt does not get bitter, so timing is forgiving.\r\nBuying it\r\n\r\nCheck whether it is kernels, silk, or a blend.\r\nCheck the brewing volume on the pack before comparing prices by bag count.\r\nBuy a food product, not seed corn or popcorn kernels intended for popping.\r\n\r\nIf you like this, the related grain infusions are barley tea \u2014 toastier, and not gluten-free \u2014 and sobacha, made from buckwheat.\r\nCommon questions\r\nDoes corn tea contain caffeine?\r\nNo, unless it is blended with tea leaves.\r\nIs it gluten-free?\r\nCorn is, but check the pack: corn and barley blends are common, and barley contains gluten.\r\nCan I make it from sweetcorn?\r\nNot really. It needs dried, roasted corn. You can toast dried corn kernels in a dry pan until golden, but a ready-roasted product is easier.\r\nIs corn silk tea a health drink?\r\nIt is sold that way in some places. Treat it as a flavour choice; this page makes no health claim for it.",
