Reprocessed tea—known in Chinese as 再加工茶 (zài jiā gōng chá)—refers to any tea leaf that has undergone a secondary treatment after its initial manufacture. This extra step can involve scenting with flowers or fruits, blending with herbs or spices, instant‑drying, decaffeination, re‑firing, compression, or the creation of tea extracts and concentrates. Because the primary leaf may be green, black, oolong, white, or even pu‑ erh, the brewing parameters for reprocessed teas are not a single fixed rule but a spectrum that depends on the base leaf, the nature of the reprocessing, and the desired flavor profile. Understanding how to adjust the tea‑to‑water ratio and steeping time across multiple infusions is essential for extracting the best aroma, body, and balance while avoiding bitterness or a flat, weak liquor.
This guide provides a detailed, infusion‑by‑infusion framework for brewing reprocessed teas, covering the first three steepings, the fourth through sixth, and the seventh and beyond. It draws on classical Chinese tea manuals such as Lu Yu’s The Classic of Tea (Chájīng, 8th century), the Song‑dynasty Tea Record (茶錄) by Cai Xiang, and modern scientific studies on polyphenol extraction and
