What OSULLOC does

OSULLOC is a premium Korean tea producer and brand, operating as a wholly-owned subsidiary of AMOREPACIFIC Group. Founded in 1979 by AMOREPACIFIC founder Jangwon Suh Sung-Whan on Jeju Island, the company transformed previously barren volcanic terrain into Korea's largest organic tea farm. It operates a fully vertically integrated farm-to-cup value chain spanning three tea estates (Seogwang, Dolsongi, Hannam), the Hannam Tea Factory for processing and packaging, the OSULLOC Tea Research Institute (established 2005) for cultivar and quality development, and a portfolio of retail tea salons including the OSULLOC Tea Museum and locations in Seoul (Bukchon, Myeongdong, the OSULLOC 1979 Tea House, and a premium tea house at the National Museum of Modern and Contemporary Art). Differentiated by USDA, IFOAM, and EU organic certifications, first-mover HACCP compliance in the Korean tea industry (2002), and 45+ years of accumulated cultivation expertise.

The product portfolio is organized across six categories: matcha and milk tea (including Volcanic Isle Matcha Ceremonial, Volcanic Isle Matcha Premium, multiple milk teas, Matcha Stick, and the functional Matcha+ line with probiotics, L-theanine, and collagen); matcha snacks (milk spread, langue de chata cookies, waffles, pretzels); functional and herbal teas (kombuchas and herbals with Korean ingredients such as maesil, gugija, yuja, and ginger); blended teas (fruit and floral infusions in bag format); pure teas (single-origin organic green and oolong, including award-winning Sejak); and premium gift sets (Premium Tea Collection, Tea Edition Essence). The company has won multiple international awards including North American Tea Championship first place (2009, 2011, 2012, 2014, 2015), World Green Tea Contest Gold (2009, 2013, 2014), Beijing International Tea Expo Gold (2013), and the German iF Design Award (2020).

Revenue is generated through three primary streams: premium tea product sales via direct-to-consumer e-commerce (us.osulloc.com), retail partnerships (Erewhon, Amazon, Hmart, Mega K Food in the US; Amore Mall globally), and the OSULLOC Tea Museum and tea house experience (approximately 2 million visitors annually). The company is currently in active North American expansion, debuting at Natural Products Expo West 2026 and launching a functional Matcha Plus product line targeting the US health-conscious consumer segment. Parent company backing from AMOREPACIFIC Group provides capital, distribution infrastructure, and operational stability.
