The avocado variety with smooth, thin skin is Fuerte.
Fuerte avocados usually have pear-shaped fruit with green skin that remains green as the fruit ripens. Their relatively smooth, thin peel is easy to remove, revealing creamy, pale green to yellow-green flesh with a rich, mildly nutty flavor.
The variety originated from a chance seedling in Atlixco, Mexico. Cuttings reached California in 1911, and Fuerte soon became the leading commercial avocado in the United States. Its name means “strong” in Spanish, reportedly referring to young trees that survived an unusually severe freeze.
Fuerte was eventually overtaken commercially by Hass, whose thicker, pebbly skin makes it more durable during shipping. Hass skin also darkens when ripe, whereas Fuerte generally stays green. Reed avocados can also have green skin, but their skin is notably thicker and more glossy, making Fuerte the best match here.
