Is Mexican Guava a citrus fruit?

While both citrus fruits and guavas belong to the same family (Rutaceae), they are in different genera. Citrus fruits belong to the genus *Citrus*, while guavas belong to the genus *Psidium*.

Here's a simple way to remember:

* Citrus fruits have a characteristic sour taste and contain high amounts of citric acid (like oranges, lemons, limes).

* Guavas have a sweet and sometimes tangy flavor, but they are not sour.
