Known as the 'Queen of Fruits,' mangosteen has a relatively short but intense harvest season. In Thailand, the season runs from May to September, with peak quality and availability from May to August, coinciding with the rainy season which is optimal for fruit development. Vietnam's harvest begins 1-2 months later than Thailand, with July marking the peak supply period for Vietnamese mangosteens. The fruit is available fresh for only 6-10 weeks during peak season due to its delicate nature and limited shelf life. This short supply window leads to significant price fluctuations both within the season and year-to-year. Peak popularity in the Chinese market occurs during June-July when both countries have optimal supply, offering the best quality fruit at competitive prices. The seasonal nature makes mangosteen a highly anticipated summer delicacy.
