Strong Chai Leaves for Kadak Chai | Diamond Assam CTC Loose Leaf

Diamond is the everyday grade of Assam chai leaves we sell most of. Sourced from Assam gardens and processed by the CTC method, these small tightly rolled pellets infuse fast and give the full bodied, malty, copper red liquor that holds its own against milk and sugar.

What separates Diamond from other CTC teas is its grade. Sourced from gardens that follow strict harvesting protocols, the leaves are picked at optimal maturity to ensure maximum briskness, strength, and aroma. The double-processing technique intensifies the flavour extraction, meaning you get a stronger, bolder cup even at standard dosages. It is the grade that suits a Kolkata style tea stall cup, brewed hard with milk and sugar, and it is what we sell most of over the counter.

Whether you brew it strong with full-cream milk and two spoons of sugar, or keep it light with a splash of milk, Diamond CTC Chai delivers consistently. It is ideal as a morning energiser, post-meal digestive, or an afternoon pick-me-up. No bitterness, no astringency, just a clean, powerful chai that satisfies every time.

A 500g pouch yields roughly 120 to 140 cups. Available in 500g and 1kg pouches, and the 1kg is the one to buy if chai is a twice a day habit or you are stocking a shop or an office.

How to Brew: Add 1 tsp (3g) to 150ml water. Bring to a boil, add 100ml milk. Simmer for 2 minutes, strain and serve. Adjust milk ratio to preference.

Buying 1kg

If you drink chai every day, the 1kg pouch is the sensible unit. It is the same leaf as the 500g, priced lower per cup, and it keeps for 18 months sealed. We sell bulk loose leaf tea to households, offices and small cafes across India.

Frequently Asked Questions

Why is it called Diamond CTC?

Diamond is our name for the premium grade. It is a higher quality CTC leaf than standard commercial grades, with better briskness, colour and aroma.

Can I use Diamond CTC for masala chai?

Absolutely. Its bold body makes it one of the best bases for masala chai, holding up against strong spices like ginger and cardamom.

Is it suitable for kadak chai lovers?

Yes, this blend is specifically designed for those who want a strong, brisk, full-cream milk chai experience.
