🌽 A Brief History of Oksusu‑cha (옥수수차)
Oksusu‑cha, or Korean corn tea, is a beloved traditional infusion made not from tea leaves but from roasted corn kernels simmered in water. Naturally caffeine‑free and gently nutty, it has long been a winter comfort drink in Korean homes, often served alongside its close counterpart, bori‑cha (barley tea).
🌾 Origins & Early Use
Corn arrived on the Korean peninsula in the 1500s through trade with China and quickly became an established crop thanks to its adaptability and high yield. Drying was already a well‑developed preservation method in Korean agriculture, so farmers treated corn much like other grains—drying, roasting, and boiling it to create simple, sustaining foods and drinks. One of these was oksusu‑cha, which became especially associated with rural regions such as Gangwon Province, where it is also known as gangnaengi‑cha and traditionally enjoyed through late autumn and winter.
🏡 Cultural Significance
Like barley tea, corn tea evolved into a staple household beverage. It is commonly served to guests, offered for free in many restaurants, and brewed year‑round as an everyday drink that is both comforting and economical.
🔥 Preparation & Variations
The classic method involves roasting dried corn kernels until they deepen in color and develop a slight char, then boiling them until the water turns a warm yellow. Variations include oksusu‑bori‑cha, a blend of roasted corn and barley, and oksusu‑suyeom‑cha, made from corn silk and known for its naturally sweeter flavor.
🛒 Modern Accessibility
Once a rustic homemade drink, roasted corn tea is now widely available in pre‑packaged form—sold as loose kernels, tea bags, and instant mixes—making it easy to enjoy a traditional Korean flavor with modern convenience
