Tinghua Liquor Obtains European and U.S. Patents for Proprietary Distillation Processing Technology

YIBIN, China, September 30, 2026 (EZ Newswire) -- Qinghai Spring Medicinal Resources Technology Co., Ltd. today announced that its flagship beverage brand, Tinghua Liquor, has received official patent recognition from both European and United States intellectual property authorities for its proprietary spirit-processing technology.

The United States Patent and Trademark Office (USPTO) issued a Notice of Allowance for U.S. Patent Application Publication No. US 2024/0252453 A1, following a granted invention patent from the European Patent Office (EPO) under European Patent No. EP4353263 B1. The patent examinations conducted by European and U.S. authorities evaluated the technology strictly against established intellectual property criteria, including novelty, inventive step, and industrial applicability.

Precision Ingredient Engineering in Distilled Spirits

Traditional Baijiu brewing relies primarily on natural, open-air batch fermentation, which can lead to variance in trace compound composition. Tinghua’s patented processing system applies targeted ingredient-editing techniques — combining controlled-strain fermentation, molecular distillation, and membrane separation — to process aged liquor at the molecular level.

By utilizing modular compound identification and controlled separation, the technology aims to refine the trace chemical profile of distilled spirits. The process is designed to reduce specific volatile byproducts typically associated with harsh post-consumption discomfort while preserving the traditional full-bodied flavor profile of high-grade Baijiu.

Interdisciplinary Research Approach

Tinghua’s development framework combines traditional Chinese brewing methodologies with modern analytical food chemistry and neurophysiology concepts. The company’s research focuses on how specific trace congeners in distilled spirits interact with human sensory and physiological receptors during consumption.

About Tinghua

Ting Hua means “listening to the sound of liquor bubbles,” implying extraordinary Chinese Baijiu-making skills. As one of the world's six major distilled spirits, Chinese Baijiu enjoys a history of over 1,000 years. In ancient times, skilled spirit craftsmen determined the quality of spirits by checking the size and dissipation speed of bubbles when the spirits flowed into the barrel during distillation. Top artisans could even determine the spirits' quality by listening to the sound of the bubbles. With such amazing skills, we can study spirits in more ways to further understand the relationship between liquor and people. For more information, visit tinghuajiu.com.
