HOT ! 2025 Yunnan Sourcing \"Ku Zhu Shan\" Raw Pu-erh Tea Cake

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.
