[2] Trung Nguyên is the largest domestic coffee brand within Vietnam, and exports its products to more than 60 countries, including major markets such as the United States, the European Union, the United Kingdom, Germany, China, Canada, Russia, Japan, Dubai, Australia, and ASEAN countries, including its international hub in Singapore.

After gathering, thorough washing, sun drying, light roasting, and brewing, these beans yield an aromatic coffee with much less bitterness.

Trung Nguyên's Legendee[16] brand coffee is a simulated kopi luwak product, which uses synthetic enzymes to mimic the civet's gastric acid, producing effects on flavour similar to actual kopi luwak, and reducing the need to rely on the civet, which is now endangered in Vietnam due to excessive hunting.

In August 2010, Trung Nguyên CEO Dang Le Nguyen Vu reported that the company had begun manually producing its own natural (non-simulated) kopi luwak under its Weasel sub-brand.

It is much more expensive than any of the company's other products: a 1 kg bag of Weasel coffee costs $3,000, six times higher than Indonesian kopi luwak.
