What is
Assam tea?

The field notes

One origin.
Two leaf styles.

Assam names a tea-growing region of India, with gardens across the Brahmaputra plains. It tells you an origin, rather than one leaf shape. Both orthodox and CTC teas are made there. Our film follows two imagined packets to separate two useful questions: where was this tea grown, and how were its leaves processed?

• An orthodox example

  A packet with wiry leaves

  Mokalbari Tea Estate describes one of its Assam orthodox teas as having wiry leaves and golden tips. The longer leaf shapes in our first dish illustrate that example. They are not a rule that all orthodox teas must have the same shape or contain only intact leaves.

• A CTC example

  A packet with small granules

  In CTC processing, mechanical crushing, tearing and curling forms a granular tea. The trustea introduction explains this process, and Halmari’s Assam CTC provides a producer example of the resulting leaf appearance. The film simplifies the transformation; it is not a factory demonstration.

Tea Origins · Part 2 of 3. The name tells you where; the processing style helps tell you how it was made. When choosing a packet, look for both kinds of information. Next in this tea series, we will bring Darjeeling and Assam together.

Two teas say Assam. Why do the leaves look so different?

Assam names a tea-growing region of India, where gardens stretch across the Brahmaputra plains.

Its black teas are known for a full-bodied, malty character. Those describe the cup; malty doesn't mean malt was added.

Now open these two packets. One holds an orthodox tea with wiry leaves.

The other says CTC: crush, tear, curl. That processing breaks the leaves into small granules.

Both can be Assam, because origin and processing tell you different things.

So next time you pick up a packet, look beyond Assam. Check for the processing style, too.

The name tells you where; the style helps tell you how it was made.

Next in this tea series: Darjeeling and Assam, side by side.
