The Hass avocado is the most commercially popular variety worldwide, accounting for approximately 80% of all avocados grown globally. It is widely preferred for its rich, nutty flavor, high oil content, and creamy, fiberless texture. [1, 2, 3, 4]
Key Characteristics
- Appearance: Features a distinct thick, bumpy (pebbly) skin that changes from green to a dark purplish-black when fully ripe.
- Durability: Its thick skin makes it highly resistant to bruising, allowing it to be transported long distances without damage.
- Yield: Trees are known for being prolific, heavy-bearing, and often harvested year-round in certain climates. [1, 4, 5, 6]
History & Origin
- Discovery: It was discovered in the late 1920s by Rudolph Hass, a mail carrier and amateur horticulturist in La Habra Heights, California.
- The Mother Tree: The original tree grew from a seed of unknown parentage that refused to accept a graft from the then-standard Fuerte variety.
- Commercial Rise: It eventually surpassed the Fuerte as the industry leader in the 1970s due to its superior shelf life and consistent high yields. [1, 6, 7, 8, 9, 10]

Selection & Storage
- Ripeness Test: Gently press the fruit in the palm of your hand; it should yield to gentle pressure without feeling mushy.
- The “Stem Trick”: Flick off the small stem nub at the top. If it is green underneath, it is ready to eat. If it’s brown, it may be overripe.
- Storage: Unripe avocados should stay at room temperature. Once ripe, store them in the refrigerator for 2–3 days to slow down further ripening. [4, 17, 18, 19, 20]
