Thai pomelos are large in size, averaging 15-25 centimeters in diameter, and are globular to oblate in shape. The rind is smooth, semi-firm, light green, and pebbled with many small oil glands. Underneath the surface, there is a very thick, cotton-like pith that is white, spongy, and can reach up to twelve centimeters in width. The pith is attached to light green-yellow flesh, which is divided into 9-14 segments by fibrous membranes. The flesh can be dry or very juicy, depending on the individual fruit, and also seedless to containing many seeds. Thai pomelos are soft and have a sweet-tart flavor with citrus notes reminiscent of grapefruit.
