'Kadak' doesn't just mean strong — it means tea that stands up in milk, announces itself over sugar, and survives a proper rolling boil. That calls for a different leaf entirely from anything in the Darjeeling aisle: CTC granules, engineered for exactly this job.
The choice isn't which one is strongest (that's settled: plain Assam CTC) but which flavour of strong suits your kitchen. Here's the honest tour, prices included.
Start with the base: pure Assam CTC
Assam CTC Strong (Kadak) is the reference point — brisk, malty, almost bready, and bitter without milk by design, because it is a base rather than a solo tea. Boiled 5 minutes with milk it makes the classic no-nonsense doodh chai: the highest caffeine of the common Indian milk teas at the lowest price per cup (₹240 per 250 g). If your household drinks chai twice a day, this is the workhorse.
The spiced family
Masala chai adds the full spice cabinet to that CTC backbone — strong, malty and sweet-spiced, ginger and cardamom leading with black pepper closing the sip. Adrak (ginger) chai strips it back to one spice and turns it up: sharp fresh ginger cutting through milk and sugar, hot in both senses, the monsoon-and-sore-throat cup. Elaichi (cardamom) chai goes the other way — perfumed, gently sweet, the friendliest chai for beginners.
Two specials deserve a mention. Karak chai, the Gulf-style cup, is boiled long and hard with condensed milk and cardamom until thick and very rich — more dessert than beverage, and proudly so. And tandoori kulhad chai adds a genuine smoky char by serving masala chai in a fire-heated clay cup: creamy, caramelised, unmistakable.
The method matters as much as the leaf
Every tea above shares one rule: it must boil with the milk, not steep beside it. A polite teabag dunk produces beige disappointment; kadak chai comes from leaf, water, milk, and sugar rolling together on the flame.
- Use roughly one teaspoon of CTC per cup, more if the milk is rich.
- Boil 4–6 minutes with milk — the colour should turn a deep biscuit brown.
- Add whole spices (crushed) at the start, sugar at the end.
- For karak, be patient: the long boil with condensed milk is the whole point.
Frequently asked questions
Which is the best tea for strong kadak chai?
Assam CTC is the right base for kadak chai — brisk, malty, and deliberately bitter without milk, because it's built to punch through milk and sugar. KETLI's Assam CTC Strong (Kadak) has the highest caffeine of the common Indian milk teas and costs ₹240 per 250 g, the cheapest strong base per cup.
What is the difference between masala chai and karak chai?
Masala chai is Indian spiced milk tea — ginger and cardamom leading, black pepper closing, boiled about 4 minutes with milk. Karak chai is the Gulf style: boiled longer and harder with condensed milk and cardamom until thick, sweet, and very rich. Masala is a daily cup; karak is an indulgence.
Why is CTC tea bitter without milk?
By design. CTC (crush-tear-curl) processing shreds the leaf into dense granules that release colour, tannin, and caffeine fast — a base engineered for milk and a rolling boil, not for drinking plain. Judge a CTC by the chai it makes, never by a plain cup.
Which chai is best for beginners?
Elaichi (cardamom) chai — perfumed and gently sweet, with the cardamom softening the CTC edge. It's the friendliest introduction to strong Indian milk tea. Boil it 4 minutes with milk; ₹300 per 250 g.
