Coconut flower nectar

[5] Members of the Khmer community in Tra Vinh are reviving the practice, as saltwater intrusion into the Mekong Delta has forced farmers to turn away from harvesting the coconuts themselves.

[3][6][7] In Thailand, coconut flower nectar (Thai: น้ำหวานดอกมะพร้าว, RTGS: nam wan dok maphrao) is primarily harvested from palm sugar trees in the country's central plains region, including Samut Songkhram province.

[8] The nectar can be drank raw and fermented and distilled into an alcohol known as "drunken sugar" (Thai: น้ำตาลเมา, RTGS: nam tan mao).

[9][8] Onson (Thai: ออนชอน), founded by Tammawit "Tiger" Limlertcharoenwanich, is a distillery based in Sakon Nakhon province in Isaan, which produces a spirit from the nectar.

[2] In 2022, then Move Forward Party leader Pita Limjaroenrat listed Onson as one of his favorite Thai spirits.
