Kaluga Queen is a Chinese brand of caviar made by the caviar company Hangzhou Qiandaohu Xunlong Sci-Tech Co., Ltd. The company produces 60 tonnes of caviar annually, making it the largest producer of caviar in the world and responsible for 30% of world production. Kaluga Queen supplies caviar for 21 of the 26 3-starred Michelin restaurants in Paris.
Kaluga Queen was founded in 2003 and affiliated with the Chinese Academy of Fishery Sciences. The caviar processing facility was constructed in 2004 and the Kaluga Queen brand created in the following year.
Several years after the founding of the company, CITES imposed a severe curtailment of wild caviar from the Caspian Sea region, creating an opportunity for caviar farming startups to take market share from the traditional caviar powers of Russia and Iran.
At the 2016 G20 Hangzhou summit, which was held in the company's home province of Zhejiang, world leaders attending the summit, including Russian President Vladimir Putin, were served Kaluga Queen caviar.
