Grain Length & Elongation: Uncooked extra-long grains must measure at least 8.2 mm to 8.4 mm in average length, expanding to at least twice their size after cooking without bursting or breaking.

Aroma & Flavor Profile: High concentration of 2-acetyl-1-pyrroline, giving off a distinct, natural nutty and pandan-like fragrance that intensifies with proper aging (typically 12 to 24 months).

Texture & Cook Quality: Grains feature a soft, firm texture that remains separate, dry, and non-sticky post-cooking, with a broken grain percentage strictly below 1% to 2% in top-grade exports.
