Zi Juan (Purple Beauty)
Zi Juan, often translated as Purple Beauty, is a distinctive Yunnan cultivar whose buds, leaves, and even stems run deep purple from a high concentration of anthocyanins. It was selectively bred at the Yunnan Tea Research Institute beginning in the 1980s, propagated as a stable clonal cultivar from naturally purple tea trees, and it is usually processed as sheng (raw) puerh. The cup is unlike standard sheng: a reddish-purple-tinged liquor, a character that can lean drier and more savory, and a novelty (plus a marketed health angle) built around its pigment.
Genuine Zi Juan shows visibly purple dry leaf and a liquor with a reddish-purple or lavender tinge rather than the gold of standard sheng, plus a flavor that is often described as drier, more savory, or more astringent than a typical raw puerh. The anthocyanin pigment is pH-sensitive, so a few drops of lemon will shift the liquor toward pink, a quick informal check that real purple material is present. Because Zi Juan is a defined cultivar, the purple color should be consistent and pronounced, not a faint occasional tint. Balance matters: the better examples temper the astringency with some sweetness and body, while cheaper ones can be flatly dry. Treat it as its own thing rather than holding it to a standard sheng profile.
Zi Juan is a registered clonal cultivar developed at the Yunnan Tea Research Institute (under the Yunnan Academy of Agricultural Sciences) from the mid-1980s, propagated from a single naturally purple tree spotted in the institute's own experimental garden in Menghai (discovered in 1985, clonally propagated from 1986). As a cultivar rather than a region, it can be grown and processed in various parts of Yunnan, and while it is most associated with sheng, the purple material is also made into ripe and black tea. Its defining feature is the high anthocyanin content, the same pigment family that colors purple fruits, which the plant produces in response to strong highland sun.
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 keep the cultivar's tendency toward dryness in check while the color and aroma come through. Expect 8-10 infusions. Western: about 3 g per 200 ml, 90-95°C, 2-3 minutes, re-steeping two or three times; go lighter on leaf and time if the astringency is pronounced.
Zi Juan sits in an accessible-to-midrange band, roughly €10-25 (about $11-27) per 100 g depending on material and whether it is plantation or older-tree, sold both loose and as cakes. Older-tree or single-origin purple material commands more.

Zi Juan made as sheng can be aged like other raw puerh under stable dry storage, though it is a less-traveled aging path than the classic mountains, so there is less collective experience to predict its decade-scale trajectory. Many drinkers enjoy it relatively young for its color and distinctive character.
Zi Ya (Purple Bud)
The natural counterpart: Zi Ya (purple bud) is naturally occurring purple-budded material picked from ordinary trees, where Zi Juan is a deliberately bred, uniformly purple cultivar; same pigment, different origin story.
Nannuo Mountain
Nannuo is a classic Xishuangbanna mountain; comparing Zi Juan to a standard Nannuo sheng shows how far the purple cultivar departs from a conventional balanced mountain profile.

A standard blended sheng benchmark; tasting it against Zi Juan makes the cultivar's unusual dryness, color, and savory character obvious.
Zi Juan's color is a chemistry demonstration in a cup: its anthocyanins act like a pH indicator, so adding acid (a squeeze of lemon) pushes the liquor pink while neutral or alkaline water keeps it bluer-purple. The pigment, not the usual tea polyphenols, is what makes this tea look the way it does.
