Zi Ya (Purple Bud)
Zi Ya, or purple bud, is naturally occurring purple-budded tea material: buds that turn purple from anthocyanin pigment, picked from ordinary Yunnan tea trees (often older or wild ones) rather than from a single bred cultivar. Unlike Zi Juan, which is a deliberately propagated purple cultivar, Zi Ya is selected from the purple buds that appear naturally among normal green tea trees, so it is more variable and less uniformly purple. It is usually processed as sheng (raw) puerh and prized as an unusual, anthocyanin-rich material with a character distinct from standard green-budded sheng.
Genuine Zi Ya shows purple-tinged buds in the dry leaf and a liquor that can carry a reddish or violet cast, with a character that leans toward a clean, sometimes savory or honeyed sweetness when the material is good. Because it is naturally selected rather than a uniform cultivar, expect more batch-to-batch variation than with Zi Juan, both in color intensity and in flavor. Material from older or wild trees tends to give more body and complexity than purple buds picked from young plantation bushes. As with all purple tea, the anthocyanin pigment is pH-sensitive, so a drop of acid will shift the color toward pink. Look for buds with real purple presence and a cup with some sweetness and body rather than thin dryness.
Zi Ya is defined by material type rather than by cultivar or single place: it is the naturally purple buds that occur among Yunnan large-leaf (assamica) trees, gathered and processed where such trees grow, frequently from older or semi-wild gardens. This makes it distinct from Zi Juan, the bred cultivar, even though both owe their color to anthocyanins. Because the purple buds are a minority of any given harvest, Zi Ya is necessarily a selective pick, which is part of why it is treated as a specialty rather than a bulk style.
Gongfu: 6-8 g per 100 ml in a porcelain gaiwan, 95-100°C, one brief rinse, then flash steeps of 10-15 seconds extending gradually; short steeps suit the often delicate bud material and keep any dryness in check. Expect 8-10 infusions, with old-tree material lasting longer. Western: about 3 g per 200 ml, 90-95°C, 2-3 minutes, re-steeping two or three times.
Zi Ya ranges with the quality of the trees it comes from, roughly €12-30 (about $13-33) per 100 g, with old-tree or wild-tree purple buds at the upper end and plantation material lower. Single-origin old-tree Zi Ya can climb further.

Zi Ya processed as sheng can be aged under stable dry storage like other raw puerh, though as a specialty material its long-term aging behavior is less documented than the classic mountains. Many drinkers enjoy it young for the bud character and color.
Zi Juan (Purple Beauty)
The defined-cultivar counterpart: Zi Juan is a uniform bred purple cultivar, where Zi Ya is naturally selected purple buds from ordinary trees, more variable in both color and flavor.
Lao Ban Zhang
A famous old-tree sheng for reference; much Zi Ya comes from older trees, so comparing it to a benchmark old-tree mountain tea shows how the purple-bud selection diverges from conventional old-tree character.
Yiwu
An approachable standard sheng baseline; tasting Yiwu against Zi Ya highlights how the purple-bud material differs in color and profile from a classic green-budded mountain tea.
Purple buds like Zi Ya appear naturally as a kind of sun-protection response in the tea plant, the leaves loading up on anthocyanins much as some autumn foliage does; growers spot and pick these purple flushes from among otherwise green trees, which is why the material is gathered rather than grown as a dedicated cultivar.
