hass

Hass most commonly refers to the Hass avocado, a cultivar of Persea americana that has become the dominant variety in many markets. It originated in the 1920s in California, developed by Rudolph Hass, who grafted a seedling tree and named the cultivar after himself. Over time, Hass avocados supplanted earlier varieties in commercial production due to their favorable flavor, texture, and shelf life.

The fruit is typically ovoid with a rough, pebbly skin that darkens from green to purplish-black as it ripens. The flesh is creamy and rich, with a high oil content and a buttery texture that is widely prized for fresh consumption and salads. Avocados of the Hass cultivar are usually harvested before fully ripe and then allowed to ripen off the tree. The tree is relatively compact and productive, tolerates a range of soils, and requires adequate irrigation and well-drained conditions.

Global production and distribution are heavily influenced by Hass. While Mexico is the leading global producer of avocados, Hass accounts for a large share of exports from California and other producing regions. The variety is grown in numerous countries with suitable climates, including parts of Central and South America, Africa, and the Middle East. The Hass cultivar’s popularity has reshaped avocado markets by providing a consistent size, color, and taste, contributing to year-round availability in many markets.

Hass also appears as a surname and, less commonly, a given name. The name is of Germanic origin and is borne by various people in different fields, reflecting its use beyond the fruit cultivar.
