Figfinatic,
You are right . With accumulated experience, we may slowly understand what figs tell us about the way they were cultivated, their exposure to the sun, frequency of irrigation, etc,,
These two figs on the pictures are of exactly the same cultivar, taken from trees of approx the same age, but cultivated and treated differently.
The fruit with a darker colored interior did not receive any fertilizer, and was not irrigated at all.
