From Ku Zhu Mountain, near Wenshan village about 7 km southeast of Jinggu town (Pu’er / Simao), this sheng comes from naturally grown, 100+-year-old trees. Ku Zhu shows a bolder side of Jinggu, more bitter and more assertive than its sweeter Yang Ta counterpart, yet still carries a unique character often described as a meeting of Jinggu sweetness with Mengku’s clean, mineral edge. Pressed into 250 g cakes with a striking wrapper by Chengyi Lee, and made in small quantity (50 kg total). Why it’s special Old-arbor power: 100+-year material brings density, structure, and long, steady infusions. Distinct terroir: A “Jinggu × Mengku” vibe, honeyed undercurrent with alpine, mineral bite, yet unmistakably Ku Zhu. Built to age: The firm bitterness and clean profile make this an excellent candidate for mid- to long-term cellaring. Tasting notes Aroma: Wild honey, citrus peel (pomelo), alpine herbs, fresh grain, light pine. Liquor: Pale gold to light amber; thick, rounded mouthfeel with precise, lively energy. Flavor: Early steeps show measured kuwei (pleasant bitterness) with floral–citrus lift and a clean mineral line; mid–late steeps reveal gentle honey, barley/grain sweetness, and light resin. Finish & feel: Long, cooling hui-gan; persistent shengjin (mouthwatering return); focused, steady cha qi without harshness.

Brewing guide (Great water helps. Keep early steeps short; adjust to manage bitterness.) Gongfu (recommended) 6 g / 100 mL 98–100 °C (208–212 °F) Quick rinse, then 5s • 8s • 10s • 12s • 15s, adding gradually for 10+ infusions. If bitterness spikes, shorten by 1–2 seconds or drop to 95–96 °C. Western 3–4 g / 300 mL (10 oz) 95–98 °C • 2:00–2:30 2–3 infusions, adding 20–30s each round. Favor shorter times to showcase sweetness over bite. Grandpa style 1–1.2 g / 100 mL, 90–95 °C Top up as you sip. Grain-honey core with tidy florals and a clean green snap. Cold brew 8–10 g / 1 L, room-temp water; refrigerate 6–8 hours. Crisp citrus-floral lift, cane sweetness, minimal astringency. Pairing & occasions Great for side-by-side tasting with Yang Ta and with the Ku Zhu Shan Hong to explore terroir vs. processing. In Summary Caffeine: Medium to medium-high Storage & aging: Store cool, dry, odor-free, away from light; allow gentle airflow. Expect bitterness to knit and honey/mineral notes to deepen over 5–15 years.
