This coffee is naturally low in caffeine due to the 2 varietals that make up the lot.

Aramosa - a cross between Coffea Arabica and Coffea Racemosa, done to blend the low caffeine and drought resistance of Racemosa with the flavour of Arabica. Since the plant produces less caffeine, the beans always taste very sweet, floral, and devoid of any bitterness. This makes the Aramosa varietal extremely hard to grow as it naturally contains only 0.3-0.7% caffeine (regular Arabica coffee has up to 1.8%).

Laurina - a rare, low-caffeine variety of Arabica coffee that has its origins on Réunion, near Madagascar. This coffee, which has only ⅓ of the caffeine of regular Arabica coffee, which gives the coffee its sweet taste (caffeine having a bitter taste). It is also known as Bourbon Pointu, so named for both its island of birth (the island of Réunion was formerly called Bourbon) and the elongated and pointed shape of the coffee.

Since caffeine acts as a coffee plant's inherent insecticide, and both Laurina and Aramosa are naturally low in caffeine, they are both more challenging to grow and harvest, leading to their relative scarcity and popularity.
