If you've ever eaten jasmine rice and thought "it all smells pretty much the same," cook a pot of Tung Kula Ronghai rice and you'll see why this area has a reputation. The aroma when you lift the lid hits harder than you're used to. The grains are long and slender, soft but never mushy, and they stay soft even after they cool instead of turning hard and stiff. Roi Et is one of the five provinces inside the Tung Kula Ronghai zone, and it's the one most closely tied to this rice. The main growing districts are Kaset Wisai, Suwannaphum, Pathum Rat, Phon Sai, and Nong Hi.
What is Tung Kula Ronghai, and why is the rice so fragrant?
Tung Kula Ronghai is a wide plain in southern Isan that straddles five provinces — Roi Et, Surin, Sisaket, Maha Sarakham, and Yasothon — covering more than two million rai. It used to be known as so dry and so salty that it was hard to grow anything, and the name "Ronghai" (literally "weeping") came from exactly that hardship. But it turns out the salty, sandy soil combined with the dry air late in the season is what stresses the rice plants just enough that they build up more of their aromatic compounds in the grain than usual. What was once a weakness became the one strength other regions can't copy.
- Variety — these are Khao Dawk Mali 105 and RD15, photosensitive varieties grown only once a year in the wet-season paddy. That keeps the yield limited and the aroma stronger than rice pushed through several crops a year.
- Soil and water — sandy loam with a mild saltiness, plus low water while the rice is heading, is the recipe that gives you deep fragrance, long slender grains, and a soft texture once cooked.
- GI registration — Tung Kula Ronghai jasmine rice is registered as a Geographical Indication (GI), with Roi Et's Thai jasmine rice trade association filing the application. Rice carrying this mark has to be grown in the actual area and meet the criteria — it isn't something anyone can just claim.
Either side of Tung Kula, same rice
Tung Kula rice sold in Roi Et, Surin, or Sisaket is all the same GI rice — the only difference is which district grew it. On the Roi Et side that's mainly Kaset Wisai and Suwannaphum. Roi Et is the province that registered this GI, so if you're buying in town and you spot a Roi Et Tung Kula community mark, that's the genuine local product.

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.
How GI rice differs from a supermarket bag
Most bagged jasmine rice in supermarkets is blended from several sources and graded to a middle-of-the-road standard — the smell is steady and consistent but never stands out. Tung Kula rice from a local community group or cooperative usually comes from one large paddy or a cluster of nearby ones. It isn't as bright white as rice that's been milled two or three times, but the aroma is noticeably stronger and it cooks up softer. If you love the smell of rice, you'll get hooked.
- Tung Kula white rice — fluffs up well, soft, with a standout aroma. Good for anyone who eats rice daily and wants that fragrance, and it's the easiest one to grab as a gift.
- Brown jasmine rice — keeps the germ on, so it has more fiber and nutrients and a chewier bite. Health-minded folks love it; it needs soaking and more water than white rice to cook.
- Organic jasmine rice — grown without chemicals and certified organic. It costs a fair bit more than regular rice, but if you're gifting it to elders or someone health-conscious, it's worth it for both the product and the thought.
- Germinated brown rice (khao hang ngok) — rice sprouted slightly before milling, which boosts the aroma and nutrients. It's a more premium-leaning gift you'll find at community enterprises and OTOP centers.
Where to buy Tung Kula rice in Roi Et
The nice thing about good rice as a souvenir is that it's sold year-round — no waiting for a season. Below are the spots people actually buy from in the province, ordered from the easy in-town options out to the source in Kaset Wisai and Suwannaphum.
Roi Et OTOP Product Display and Sales Center
The province's hub for community products, with rice from several community enterprises and cooperatives gathered in one place — white rice, brown rice, and germinated brown jasmine rice. You can compare brands and prices side by side, which makes it ideal if you want to choose among several labels or pick up rice alongside other souvenirs like silk and basketry.
A-rice brand (Roi Et BAAC Marketing Coop)
100% Tung Kula jasmine rice under the A-rice brand from Roi Et's BAAC agricultural marketing cooperative — coop rice bought directly from local farmers. It comes in both 1 kg and 5 kg bags, available at souvenir shops in town and through coop channels. If you want a gift where the money reaches the farmers, this is one you can buy with a clear conscience.
Khao Phet Tung Kula group (Dong Khrang Yai, Kaset Wisai)
A jasmine-rice community enterprise in Dong Khrang Yai subdistrict, Kaset Wisai district — one of the Roi Et-side sources of Tung Kula rice. They sell white rice, brown rice, and organic rice from local paddies. If you're driving through Kaset Wisai and want to support the group directly, this is the source pin where you'll get fresh stock.
Tung Kula 101 brand rice
100% white jasmine rice under the Tung Kula 101 brand — a Roi Et rice marketed clearly as a gift pack, in nice carry-ready bags. You'll find it at souvenir shops in town and the larger malls. Good for anyone who wants a presentable bag to give without having to track down a community group.
OTOP shop at Roi Et Airport
A souvenir shop in the Roi Et Airport passenger terminal, stocking quality community products including Tung Kula jasmine rice in carry-ready bags. It's the most convenient option for anyone flying home — buy before you check in, no need to detour into town.
Noei Sot Park (jasmine rice cake)
A cafe and souvenir shop on Roi Et's bypass road, known for cakes made with jasmine-rice flour — a processed souvenir that's different from a bag of rice grains. Good to buy as a snack to go with the rice itself, and a nice spot to sit with a coffee before you carry on.
Suwannaphum large-plot paddies
Suwannaphum district is another Roi Et source of Tung Kula rice, with large-plot paddy groups that mill and bag their own rice to sell. If you're heading down toward Surin–Sisaket, stop and ask the groups in the district — you'll get rice from the source at a good price.
Fresh markets and rice shops in town
If you don't want to chase a specific brand, several rice shops and fresh markets in Mueang Roi Et carry Tung Kula rice scooped by the kilo. It's cheaper than buying a gift pack, but ask clearly whether it's genuine Tung Kula rice or a blend.
Straight talk
Source-side community groups like Khao Phet Tung Kula or the large-plot paddies mainly focus on wholesale and online channels. If you're going to drive in to buy at the shopfront, call ahead to check they're open that day and have small bags in stock to carry off, so you don't waste the trip. In town and at the airport it's easier to buy, but the per-kilo price runs a little higher because it's a gift pack.
How to pick rice for gifting without going wrong
- Look for the GI mark or organic certification — if you want the genuine local product, look for the Tung Kula Ronghai jasmine rice mark, or an organic certification logo on the bag. Don't buy on words alone.
- Check the milling date — the fresher the milling, the stronger the aroma. If the bag lists a milling or production date, choose the freshest. Old rice gradually loses its scent.
- Choose vacuum-sealed if you're traveling far — vacuum bags hold the aroma and keep weevils out better, which suits carrying onto a flight at Roi Et Airport or passing the rice along.
- Buy a hand-friendly size — 1–2 kg bags are easy to carry and you'll finish them before the scent fades. A 5 kg bag is fine for elders, but it's heavy and you'll need to portion and seal it well.
- Tell the recipient about brown and germinated rice — these two don't cook like white rice; they need soaking and more water. If you're gifting them to someone unfamiliar, pass along the cooking method so they don't end up with hard rice.
Which rice gift lands best with whom
For elders/relatives
A 5 kg bag of certified organic jasmine rice carries weight in both substance and intention, and the recipient can cook from it for a long while.
For coworkers
A 1 kg vacuum-sealed bag of Tung Kula white rice is light to carry, easy to hand around to several people, easy on the wallet, and memorably fragrant once cooked.
For the health-conscious
Brown jasmine rice or germinated brown rice — high fiber, lower sugar than white rice — hits the mark for anyone watching their diet.
Buy rice and visit the Tung Kula source
If you're already coming through Kaset Wisai or Suwannaphum, where the rice comes from, leave some time to look around. From late rains into early winter the paddies turn green and then start to glow golden — that's the best window for photos of the fields. When the rice heads out and the whole plain turns gold, it's a sight you won't get in the city. You can fit in a stop at Ku Ka Sing in Kaset Wisai, an old stone sanctuary, on the same route.

If you want to keep exploring
If you still have time in town, stop by Bueng Phlan Chai in the city center and the Phra Maha Chedi Chai Mongkhon in Nong Phok district — two go-to spots that pair well with a Roi Et visit. Check the opening and closing hours of each before you set out so you don't miss them.
