The Harney and Sons Guide to Tea has the following to say about CTC tea:
Today, both Flowery and Broken teas are also called “Orthodox” teas, to distinguish them from “CTC” teas. “CTC” teas (so called for the “Crush, Tear, and Curl” steps of the production process) were introduced into the market in 1931, when Sir William McKercher invented the a machine that would “crush, tear, and curl” the fresh tea leaves in one fell swoop. This technique, the apogee of British tea innovation, revolutionized the world of tea production. Essentially a massive sieve, the machine extruded fresh leaves as tiny bright green pellets, then sent them on a conveyor belt beneath powerful blowers. This machine so hastened oxidation that the pellets turned dark brown within one hundred yards, in just under an hour. The result of this near instantaneous oxidation was a tea with extraordinary briskness and consistency. CTC teas have much less of the sort of internal variation that pure whole-leaf teas can provide, the kind of magical alteration that happens when one sips a fine tea or wine. CTC teas are so much cheaper and easier to produce, however, that they have almost entirely supplanted Orthodox teas. Today, CTC teas make up at least 95 percent of the worldwide tea market and are the primary ingredient in teabags. But because they are so blunt, I include only one CTC in this book. All the other British Legacy Teas here are Orthodox, and of those, almost all are Flowery.
I've searched for images of CTC tea, as this one; but in real life, I've not encountered a tea that looks like in those images.
For example, the following is an image (on 0.5 cm paper grid) of an exceptionally cheap (3.50 € for 500 g) Ceylon tea I bought.
Obviously, even this tea doesn't look remotely like the linked image of CTC tea.
Question: How can one unambiguously differentiate CTC tea from orthodox tea by looking at the dry leaves?
