Thailand’s GI-registered coffee products generated total sales of 1.497 billion baht in 2025 (B.E. 2568), with the top five items alone accounting for 1.318 billion baht, according to the Department of Intellectual Property.

Director-General Oramon Sapthaweetham said Thailand currently has 11 GI coffee registrations across eight provinces: Doi Tung (Chiang Rai), Doi Chang (Chiang Rai), Thep Sadet (Chiang Mai), Doi Suan Ya Luang Nan, Doi Muser Tak, Wang Nam Khiao (Nakhon Ratchasima), Dong Mafai (Nakhon Ratchasima), Ranong, Khao Thalu (Chumphon), Tham Sing Chumphon and Krabi Town coffee.

She said each GI coffee has distinctive characteristics linked to its production area — including altitude, rainfall, temperature, soil composition, and local farming know-how — which shape flavour, aroma and other unique qualities, creating strong economic value and consumer recognition.

1) Doi Suan Ya Luang Nan coffee
The highest-value Thai GI coffee, with sales of more than 526 million baht from output of 2,257 tonnes. Average retail price is about 500 baht per kilogramme, up 1.78 times from 280 baht/kg before GI status. The arabica is grown in Doi Suan Ya Luang, Tha Wang Pha district, Nan, at 1,000–1,500 metres above sea level, producing a profile described as chocolate, nut and fruit aromas with a rounded, intense taste and a distinctive herbal spiciness.

2) Ranong coffee
Sales of more than 262 million baht from output of 947 tonnes. Average retail price is about 600 baht/kg, up 7.5 times from 80 baht/kg pre-GI. A robusta variety with a history of introductions from Penang more than a century ago, Ranong is described as the largest robusta producer in Thailand’s Andaman-side South and the country’s second-largest overall, with bold flavour and a distinctive aroma.
