The Hass variety represents the majority of avocados consumed in the United States. Each variety of avocado has its own varietal characteristics. For example, Hass Avocados are known as the "year-round avocado" because of their availability. The Hass Avocados in your grocers' produce section are grown in California, Chile, Mexico, New Zealand and The Dominican Republic. That assures you of a ready supply of fresh fruit 365 days a year. Hass Avocados are oval shaped, with a small to medium sized seed, they range in weight from 5 to 12 ounces, and have a creamy texture with a great taste. They also have a distinctive skin that may turn from dark green to purplish-black when ripe.
