Hangzhou Cheerday Brewery Co., Ltd. (千岛湖啤酒) was founded in 1985 and is located in Hangzhou, Zhejiang Province, China. The brewery is situated near Qiandao Lake (Thousand Island Lake), a region celebrated for its exceptionally clean and natural water sources, which form the foundation of Cheerday's brewing philosophy. Over the decades, the brewery has grown into a well-established producer with regional and international reach, and was even designated as an officially recognised beer partner for the Hangzhou Asian Games. Cheerday's portfolio centres primarily on approachable, easy-drinking lager styles, including their flagship American-style lager available in formats ranging from 488ml bottles to 1-litre cans. The brewery also produces a Weissbier, demonstrating some breadth beyond its core lager range. Their beers are brewed at relatively modest alcohol levels — often around 3.1% to 3.3% ABV — reflecting a style tailored for wide consumer appeal. The brewery holds a provincial-level enterprise research designation, indicating investment in brewing quality and development. Cheerday is perhaps best known internationally through its Lucky Buddha Beer, a Chinese lager packaged in a distinctive Buddha-shaped bottle that has found distribution across global markets, including the United States and Europe. The brewery earned a Silver Medal at the 2023 Melbourne Royal Australian International Beer Awards, affirming its standing on the international stage.
