How to Brew Tongba and Chhaang at Home

---

Before the steps, the story: you're about to brew what the Limbu people have made for centuries. Tongba is infused, not heated. Chhaang is filtered and shared.

Whether you’re sipping by the fire or sharing at a summer gathering, this Himalayan drinks guide will walk you through how to brew Tongba and brew Chhaang the traditional way, all made easier with Yak&Brew. Inspired by the Limbu, Sherpa, and Tibetan communities that have preserved these rituals over generations.

Quick Overview  
You’ll follow the same first three steps for both brews:  

1. Cook + cool grains  
2. Add yeast  
3. Ferment setup

Then choose your path: brew Tongba (100% red finger millet, hot steeped) or brew Chhaang (50% red finger millet + 50% white rice, strained drink).  

Step 1: Cook and Cool the Grains
- Rinse until water runs mostly clear  
- Cook (rice cooker, multigrain, steamed, or Instant Pot)  
- Spread on trays/plates and cool completely  
Important: grains must be under 90°F before adding yeast (hot grains kill yeast)  

Step 2: Add the Yeast
- Use 1 Yak&Brew yeast sachet (Murcha Style or Easy Everest)
- Dissolve yeast in ½ cup warm water (85 - 95°F)
- Optional starter: add 1 tsp sugar + 1 tbsp cooled millet
- Wait 10 - 15 min (until bubbly/aromatic)
- Mix into the cooled grains using clean hands or a wooden/plastic spoon (avoid metal).  

Step 3: Primary Fermentation Setup (Both)
- Pack grains into the fermentation bag
- Wrap loosely in 3 - 4 grocery bags (not airtight)
- Insulate with a towel/blanket
- Store in a dark, warm place at room temp (70 - 90°F)

Choose Your Brew  
Option A: Brew Tongba (Warm Ritual)
Ferment:
- Primary fermentation: 48 hours in the fermentation bag  
- After that, transfer grains from the bag to an airtight, nonmetal container  
- Secondary fermentation (storage/maturation): let it continue developing for another 5+ days  
- Ready: typically day 7 - 10  

Best time to enjoy: after 3 - 4 weeks of maturation (flavor deepens over time).  
Store: in an airtight, nonmetal container in a dark, warm place (70 - 90°F ideal).  

To serve (hot steep):
- Pack fermented grains into a mug/vessel  
- Add hot water (150 - 170°F)  
- Steep for 5 - 10 min  
- Sip through the Pipsing straw and refill up to 4 times  
Taste: bold, earthy, comforting.  

Option B: Brew Chhaang (Cool Refreshment)
Ferment:
- Primary fermentation: 24 hours in the fermentation bag
- After that, transfer grains from the bag to an airtight, nonmetal container  
- Secondary fermentation (storage/maturation): let it continue developing for another 5+ days  
- Ready: typically day 4 - 7  

Best time to enjoy: after 2 - 3 weeks of maturation (flavor deepens over time).  
Store: in an airtight, nonmetal container in a dark, warm place (70 - 90°F ideal).  

To serve (strain + sip):
- Scoop fermented mash into the Chalni (strainer) or a cheesecloth bag  
- Submerge in warm water (120 - 140°F)  
- Squeeze to extract liquid  
- Repeat until the liquid runs light  
- Chill or enjoy at room temperature  
Taste: smooth, lightly sweet, gently fizzy.  

Flavor & Fermentation
Tongba and Chhaang are naturally fermented and continue to enrich in both flavor and strength as they mature. The longer they ferment, the bolder their character becomes.  

Strength varies with time, temperature, and method, traditionally ranging from mild to moderate.  

Best Practices (Read This)
- Avoid metal during/after fermentation (use glass, ceramic, or plastic)  
- Sanitize tools and containers  
- Wrap loosely for primary fermentation (yeast needs airflow)  
- For secondary/maturation: go airtight and burp daily (quickly, don’t leave open)  
- Taste twice a week, especially with Chhaang (it moves faster).  

Mold warning: fuzzy growth, pink/green spots, or foul odors = discard the batch.
