One of the most common questions our guests ask is this, and we want to share the answer with everyone who has the same curiosity:

Why are bitter oranges planted in the streets of Córdoba?

The orange trees that adorn the streets of cities like Córdoba or Seville produce bitter, not sweet, fruit. This is because these trees were chosen primarily for their aesthetic, ornamental, and air-purifying functions rather than for fruit production intended for consumption. Bitter oranges are not edible in their natural state due to their acidic and bitter taste, but they have many other interesting uses.

Uses of Bitter Oranges

Bitter oranges have multiple applications. They are ideal for making marmalades, as their strong, acidic flavor makes them the perfect base for this preparation. They are also used to make a very unique wine: orange wine. This can be made by fermenting orange peels or even whole oranges. Its distinctive flavor, a balance between sweet and acidic, offers a delicious way to enjoy the unique properties of these fruits, so characteristic of the region.

Additionally, bitter oranges are highly valued in the perfume industry due to their fresh, citrusy fragrance. Their essential oil is extracted and used in the creation of perfumes and cosmetic products.

And let’s not forget their important role in urban air purification: the peels of bitter oranges absorb gases and pollution that are common in city environments, helping to provide cleaner air and a pleasant fragrance from their blossoms, fruit, and leaves.

How to Identify Bitter Orange Trees

Bitter and sweet orange trees can be easily distinguished by the size and texture of their fruit. Bitter oranges are generally smaller, with a thicker, rougher peel, whereas sweet oranges tend to be larger and have a smoother peel.

Here’s a little-known fact: to determine with certainty whether an orange tree produces bitter oranges, simply look at its leaves. If there is a small, heart-shaped structure at the base of the petiole, it’s a bitter orange tree. Additionally, bitter orange trees have thorns, while sweet orange trees do not.
