A Look Inside the Glenburn Tea Factory

Smelling freshly-made tea, just seconds out of the dryer

We've traveled to West Bengal, India, from Siliguri up the mountain into Darjeeling, onto the Glenburn tea estate, through the tea fields, and now into the factory.

Darjeeling tea is prized for its its unique flavor profiles.  First flush teas (picking will begin in March) can command very high prices.  The general process of making Darjeeling tea is this:
  • Withering
  • Rolling
  • Oxidation (often called Fermentation, tho technically that's a different chemical process)
  • Drying
  • Sorting and Packaging

The withering trough is a wind tunnel with a nylon mesh lining for the tea.  The purpose of withering is to reduce the moisture content of the leaf and to make the leaf supple.  Yet it's more than that, too.  Withering greatly impacts the flavor of the final product.  Longer withers yield different flavor profiles, and it is up to the skilled factory workers to know what is right for this flush of tea.  One of these experts remains with the withering tea all night, constantly checking the state of the leaf.  The trough begins with about three inches of leaf, and it withers down to about one inch.

"Super Twist" rolling machine - love that name!

Rolling used to be done by hand and foot.  Today, most tea is rolled by machine.  The rolling machine works in a circular manner, to twist and style the tea.  During rolling, the leaf's cellular walls are ruptured, thus beginning the oxidation process. 

The next step, oxidation, "determines the cup."  Oxidation is where it all comes together.  I'm over simplifying, but think of it as this season's unique tea + withering + oxidation gets us to the flavor profile in the cup.  When the tea has reached its desired state, it's moved into the dryer.  (See top pic.)  Drying stops the chemical reactions of oxidation.  Then off to the sorting rooms to be graded by size.

The women in the sorting room cover their faces because it can be dusty work, but it's out of the elements, and is a highly desired job.  Six different grades of tea (based on size and wholeness) will be sorted.

How amazing to get to see all this up close and personal! We think of our cup of tea as such a simple thing, and yet, just *look* at all the effort that goes into it!
