A condiment house on the edge of Bangkok.

Golden Mountain is the English name of Phu Khao Thong (ภูเขาทอง), a Thai seasoning-sauce brand made by Thai Theparos Public Company Limited. The company’s head office is in Thai Ban subdistrict, in Mueang Samut Prakan district, the province that borders Bangkok to the south, and English Wikipedia describes Thai Theparos as “a leading Thai condiment manufacturer.” The company is listed on the Stock Exchange of Thailand under the ticker SAUCE, a symbol that says plainly what the business does.

The brand website, goldenmountainsauce.com, presents Golden Mountain as seasoning for Thai home cooking and describes the brand as one that has long been part of Thai households. In its English pages the company sets out its aim in a single line: to be a leader of the condiment business in Thailand. It says it makes its sauces with quality ingredients and to the required food standards, and it signs off its brand copy with a short slogan, “It’s your taste, your happiness.”

The company dates its best-known product by sales rather than by a founding story. On its product page for the green-cap seasoning sauce it calls the bottle the top-selling product of the company and says it has been the best seller in Thailand for more than 60 years. That is the company’s own claim, and it is the main piece of age the brand itself puts forward.

Thai Theparos also has a place in the history of sriracha. English Wikipedia says that Sriraja Panich, the chilli sauce created by Thanom Chakkapak in the seaside town of Si Racha and first sold in 1935, was acquired together with its recipe by Thai Theparos in 1984, after which distribution was expanded in Thailand and abroad. The encyclopedia’s photograph of a bottle of the sauce is captioned as Sriraja Panich “by Thai Theparos Food Products.” In 2013 Bon Appétit reported that Eastland Food Corporation, the American distributor of Sriraja Panich, called it the original sriracha sauce.

Four caps, one bottle shape.

The core of the range is a family of seasoning sauces that the company names by the colour of the cap: green cap, yellow cap, red cap and brown cap. Alongside them the Golden Mountain line includes a cooking seasoning sauce, a light soy sauce and a distilled vinegar. Of the four, it is the green cap that the company calls its top seller.

The company’s own description of the green-cap sauce is specific. It says the sauce contains 75 per cent soybean sauce, with sugar and salt, and that it is made from soybeans processed to break down the protein into amino acids, which it says gives the sauce its aroma “in Golden Mountain style.” It recommends the bottle for stir-fries, marinades, soups and braises, for pa-lo, the Thai-Chinese five-spice stew, and for nam jim jaew, the dipping sauce served with grilled meat. The vinegar, the company says, is made by fermenting ethyl alcohol to obtain acetic acid at 5 per cent.

For export the company lists a slightly different selection: green-cap and yellow-cap seasoning sauce, soy sauce, a hot and spicy chilli sauce, oyster sauce, distilled vinegar, a tomato ketchup that the company says is made with tomatoes from Australia, and a blend of ketchup and chilli sauce sold as GM Hot Ketchup. Thai Theparos also sells two further brands from the same website: Kinzan, a Japanese-style shoyu, and E Zeee, which covers barbecue sauce, oyster sauce and chilli sauce.

The website works as a recipe book as much as a catalogue. It is published in Thai and English and sorts its recipes by pork, beef, duck, chicken, seafood, egg, vegetables and vegetarian food. A series of menus is credited to a cook called Mom Pom, and some dishes carry a “Scan for Cooking” QR code, from vegetarian fried rice to honey-roasted pork ribs; a stir-fried holy basil dish is billed under the brand’s own name.

Design and documentation.

The seven brands in this group all make sauces, snacks or pantry staples, and all of them come from Thailand: Mae Ploy, Tao Kae Noi, Healthy Boy, Squid Brand, Golden Mountain, Lobo and Chaokoh. Thai food brands in general sit at many different points in the trade, from family firms that still carry a founder’s surname to names that now belong to much larger food groups, and a single brand can be sold everywhere from a fresh market to a supermarket shelf abroad.

A food brand’s identity is usually carried less by a single product than by a pack, a name and the dish or snack it promises, because the company behind the name may have changed hands, moved its factory or grown far beyond the town where it started. That makes the questions behind each name worth asking plainly: who started it, who owns it now, and where its products are actually made and packed.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its products are made and how its packaging has changed — and marks plainly what rests only on the company’s own word.

A jingle, four tastes and a cap colour.

Golden Mountain’s advertising has leaned on music and on everyday food. Thai Wikipedia records a 2013 television commercial for the green-cap seasoning sauce built around the song “Charoen Charoen,” performed by the luk thung singer Takkatan Chollada with Ratchanok Srilophan, the comedy duo Kokai and Nai Son, and James Chinnakrit; the encyclopedia credits the original song to Got Jakraphan. The same commercial is listed in the biography of Sonthaya Chitmanee, which describes it as an advertisement for the green-cap sauce with those performers.

More recent work on the company’s advertising page takes a documentary turn. Under the title “Every Dish Has A Story” (in Thai, “because every dish has a story”) Thai Theparos has published a teaser and four short episodes, each named after a taste and set in a real eatery. The first, “bitter,” visits a cook at Kasetsart University; the second, “bland,” a doctors’ canteen in Khon Kaen; the third, “salty,” a wonton noodle shop at Tha Phra Chan in Bangkok; and the fourth a jok, or rice porridge, shop in Sam Yan. Each episode title carries the company’s name.

The company’s community work appears on the same site. Its news pages describe a community-relations programme in 2026 at a Songkran festival on the coast of Samut Prakan, scholarships with school uniforms for the children of employees, and a careers-market project at a school in Ang Thong province. These are presented as company activities rather than as advertising.

The sister brands follow the same practical approach. Kinzan is presented as a Japanese-style soy sauce and E Zeee as a set of table sauces, while Sriraja Panich, which English Wikipedia attributes to the company, carries its own long history from Si Racha.

For a design guide, Golden Mountain shows how a single product feature, the colour of a bottle cap, can become the way a whole range is named and remembered. Compare Maggi, the Swiss seasoning sauce sold in a similar role around the world, and Huy Fong’s Sriracha, the American chilli sauce whose style takes its name from Si Racha, the town where Sriraja Panich began. For this guide we use a cap green, a gold and a soy brown with a sans, an unofficial interpretation; no product or logo is reproduced.
