Jasmine rice is a Thai staple you can buy anywhere, but once it carries the name Thung Kula Ronghai, serious rice eaters treat it as a different grade entirely. Thung Kula Ronghai is a wide plain spread across five provinces — Roi Et, Surin, Sisaket, Yasothon, and Maha Sarakham. The Surin side sits around Tha Tum and Chumphon Buri districts. The soil here is sandy loam with a faint saltiness, which sounds like it would make farming hard, yet it's exactly the reason the rice here builds up more fragrance and softness than usual.
Thung Kula Ronghai rice is registered as a Geographical Indication (GI) product, which means only Khao Dawk Mali 105 or RD15 varieties grown in the Thung Kula zone during the main rainy-season crop can use the name. To be fair, the everyday jasmine rice bagged in supermarkets is perfectly tasty too — but if you want rice that comes with a story and a clear source, Thung Kula rice from the Surin side is the kind you can carry home and talk about with a straight face.
What makes Thung Kula Ronghai rice special
Locals sum up Thung Kula rice in four short words: fragrant, long, white, soft. These four are what set it apart from ordinary rice. Here's what each one actually means once it's on your plate.
- Fragrant — a natural scent like soft pandan that comes through the moment you cook it, no additives needed. New-season rice early in the harvest smells the strongest.
- Long, slender grains — the grains are long and elegant, hold together when cooked, and look neat on the plate.
- White — a clear, creamy white rather than cloudy, the hallmark of genuine Khao Dawk Mali 105.
- Soft — cooks up soft and separate without clumping into mush, and doesn't go hard and dry as quickly once it cools.
The reason behind all this is the soil and climate of Thung Kula. As the late rainy season turns to the cool season, the air drops and the soil starts to dry out, so the rice plants store up aromatic compounds and starch to the fullest before harvest. That's why the same variety grown in Thung Kula carries a different scent and softness than it does grown elsewhere.
How new rice differs from old rice
New-season rice (harvested around November–December) is more fragrant and tender, but you'll need to use a little less water when cooking because it soaks up moisture readily. Older rice held over from the previous year cooks up drier and more separate, which suits fried rice or khao man gai. If you're buying it as a souvenir to eat at home the regular way, go for new rice for the fullest aroma.

Half a day with a local who knows the lanes — or cooking a dish yourself — teaches you more than just eating. Book ahead on Klook or GetYourGuide.
8 places to buy Surin jasmine rice
There are plenty of ways to buy Thung Kula rice from the Surin side, from local-goods markets in town you can stop by on the fly, to co-ops and farms that grow it themselves. We've ordered them by how convenient they are for travelers — if you're short on time, hit the in-town spots first; if you want to go straight to the source, drive out to the outer districts.
Surin Local Goods Market (Provincial Commerce Office)
The easiest stop for travelers, right in town, gathering Surin's souvenirs in one place — Thung Kula jasmine rice, GI rice, silk, and rice-based products. The nice part is you can compare several brands and producers of rice in one go, weighing labels against bag sizes at your leisure. Good for anyone who wants to knock out all their souvenirs in a single trip.
Chumphon Buri Agricultural Co-op (Surin-side Thung Kula rice)
The real deal for Thung Kula rice in Surin, because Chumphon Buri is a district that sits squarely within the Thung Kula Ronghai zone. The co-op buys rice from local farmer-members and mills it itself, so you get 100% Thung Kula rice. There are small 500-gram bags for little gifts and 5 kg bags, with good prices straight from the mill — or you can order through surinbest.com.
Satom Organic Farm
An organic rice farm run by a farmer's family in Chom Phra district, growing Surin jasmine rice, riceberry, and native varieties without chemicals. Good for anyone after organic rice with a clear origin as a health-minded gift. You can visit the farm directly — there's a farmstay and rice-learning activities too, which turns buying rice into a little outing in itself.
Jib Tong Surin Rice Mill (Chang Mee Chai brand)
A long-established rice mill on the Surin–Sangkha road selling quality Surin jasmine rice under the Chang Mee Chai brand. Buy at the mill and you get fresh, freshly milled rice at mill prices — good for anyone driving this route or buying several bags at once to share around.
Sor Kor Tor Surin rice (BAAC)
100% Surin jasmine rice under the Sor Kor Tor brand from the BAAC marketing co-op. It's a standard rice that locals in Surin buy regularly, found at souvenir shops and orderable via Thailand Post (Thailandpostmart). If you want a trusted local brand, this one is easy to find.
Prasat Agricultural Co-op
Another co-op that mills 100% jasmine rice and sells it under its own Prasat Agricultural Co-op name. Good for anyone already touring the Khmer temples around Prasat district — swing by and grab co-op rice on the way out. You get rice from a local co-op at friendly prices.
Tra Mee Khun (Sangkha OTOP)
Top-grade specially selected Surin jasmine rice under the Tra Mee Khun brand, an OTOP product from Sangkha district that carries the Surin local-goods seal. It's graded rice that suits gifting in nice packaging — it looks formal enough to give to elders.
surinbest.com (Surin local goods online)
If you only remember you forgot to buy some after the trip, this site gathers jasmine rice and Surin goods from several co-ops in one place — Thung Kula rice, organic rice, and processed products, shipped to your door. Good for anyone who wants the real thing from the source but is no longer in the province.
How to buy the real thing from the right producer
Look for the Thung Kula Ronghai GI seal on the bag, or buy directly from co-ops in the Tha Tum–Chumphon Buri area for the surest bet. If you're buying at the local-goods market, ask the seller which season the rice is from — new rice will list the latest production year. A bag that just says ordinary jasmine rice isn't necessarily bad, but it may not be the genuine Thung Kula rice you set out to buy.
Pick the right rice for the person
Different kinds of rice suit different recipients. Pick along these lines so your gift lands right.
White Thung Kula jasmine rice
The standard pick that pleases anyone — fragrant, soft, easy to eat. The 5 kg bag is the best value if you're gifting people who eat rice as a staple.
Organic rice (Satom / organic groups)
Grown without chemicals, good for health-conscious recipients or homes with small children and elders. A bit pricier, but with a clear origin.
Small bags, 500 g–1 kg
Small, light gifts, good for handing out to several people or carrying on a flight — and a chance to taste before buying a big bag.
Native rice / riceberry
For anyone after something more unusual than regular jasmine rice — the colored rice from organic farms is a gift recipients rarely come across.
Cooking and storing Thung Kula rice
- Use a little less water for new rice — new rice soaks up moisture readily, so the usual amount of water can leave it soggy. Try cutting it by about 10% and adjust to taste.
- Rinse gently, just enough — scrubbing too hard washes the fragrance and nutrients away with the water. Rinse until the water runs clean and stop there.
- Store dry and sealed — keep out moisture and weevils by using a zip bag or a lidded container, kept somewhere cool and out of the sun.
- Eat new rice within a few months — the sooner you eat jasmine rice, the more aroma you get; leave it too long and the scent gradually fades.
