California almond classifications & varieties.
California almond varieties are categorized into five broad classifications based on distinguishing characteristics such as size and shape. Approximately 90 percent of almond production in California falls into the following three major classifications: Nonpareil, California, and Mission. Within those classifications there are over 30 almond varieties, many of which are grown in California. Some varieties may fall under more than one classification since they have characteristics of one type (such as Mission), but are also blanchable (a requirement of the California classification).
