Geographical indication protection of “Tú Lệ” for sticky rice
On 29 December 2020, Director General of Intellectual Property Office of Viet Nam has issued Decision no. 4926/QĐ-SHTT on granting Geographical indication registration certificate no. 00100 for the famous “Tú Lệ” sticky rice. People’s Committee of Văn Chấn district is the organization in charge of managing this GI.
Tú Lệ is a commune situated in a 3,000-hectare large valley under the mountain ranges of Khau Phạ, Khau Song and Khau Thán. It is known for the alluring scenery of the Northwest, the special sticky rice, natural hot spring and sacred traditions of the Thái ethnics.
Mr. Hoàng Văn Túi, an elder in Phạ Dưới hamlet, Tú Lệ commune of Văn Chấn district told us an old tale on the origin of the sticky rice. Back then, the local people only grew rice, and if there were droughts or diseases that make growing rice difficult, they would have to venture into the woods to find food. New year came, a man had nothing to make offerings to his parents’ altar, so he cried to the heaven. Touched by his filial piety, “Then” (deity in ethnic tongue) told him to go to Khau Phạ - the Heaven Gate, the “faerie” would give him good seeds of rice that would guarantee bountiful crop. Following the instruction, the man went upstream to Khau Phạ, and by afternoon he saw a patch of rice growing by the stream. However, the grains were mostly eaten by rodents and birds, only a few remained. He brought the grains back to plant all over the Northwest, but nowhere produced such yield as told by the deity. The seeds mostly resulted in underdeveloped plants, while some did not sprout at all. When he reached Khau Phạ pass, he stopped by Nậm Lùng stream to get water. Realising the water are clean, surrounded by a fertile valley, he decided to stay and created a rice farm there. The “faerie” rice flourished, and the rice ears exuded a pure fragrance. When the rice was ripe and milled, the grains were large, purely white and had alluring fragrance. The variety is then named ‘“Nếp tan lả” (“Khẩu Tan Chạu” in native tongue).
Keeping their ancestors’ cultural customs and traditions, the people of Tú Lệ consider “Nếp tan lả” rice as jewels bestowed upon them from the Jade Emperor. Every October, the Thái ethnics of Tú Lệ hold the New Rice ceremony to pay respect to the deity who entrusted them with the rice.
