David Rio is an award-winning, premium chai and tea company based in San Francisco, California, offering customers only the finest products domestically and around the world.  Established by co-founders David Scott Lowe and Rio Miura in 1996, we first started as a line of specialty tea, coffee, and accessories through an all Japanese catalog, and transformed into America’s premier chai company.  Today, David Rio is available in cafés, restaurants, and specialty food stores across the U.S. and in over 50 other countries.

We also opened our first retail location based in San Francisco, Chai Bar by David Rio, where David Rio products are served.



At David Rio, we strive to be the global premium chai brand, exceeding customers' expectations, offering exceptional taste and quality, and delivering meaningful customer service.  We also strive to earn the respect and trust of all business partners, giving back to the communities that are instrumental in our success.​​

Our objective is to be the premier brand in the industry and deliver a rich, indulgent chai experience that will keep even the most discerning chai drinker coming back for more!



David Rio was founded by Rio Miura and David Scott Lowe in 1996.  They first began selling specialty teas, coffees, and accessories through an all-Japanese language catalog for export to Japan, Rio's native country.  David Rio’s first chai,
Elephant Vanilla, was intended to be sold in Japan only, but immediate domestic demand from both individuals and wholesalers led David Rio to offer its chai in the US market.  David Rio’s success with Elephant Vanilla inspired Scott and Rio to create a new chai with stronger spice notes and developed its second blend, Tiger Spice Chai®, which quickly became the company’s signature chai.  Since then, David Rio has continued to create innovative flavors under its "Endangered Species Line" of premium chai products, to demonstrate its commitment to animal welfare.  Each product is named after endangered, at-risk, or vulnerable animals.

With this deep commitment to animal welfare, David Rio donates annually to the International Fund for Animal Welfare (IFAW)’s elephant and tiger programs. These donations contribute to IFAW's global initiatives, such as protecting endangered tigers and elephants around the world.  David Rio has also supported the San Francisco Bay Area’s Peninsula Humane Society & SPCA since 2002, as well as partnered with Cat Tales Zoological Park in Mead, Washington since 1999, where the company adopted a Bengal Tiger, Atlas.

Today, David Rio's premium chai and tea products are available in cafés, restaurants, and specialty retail stores in over 50 countries around the globe.  With its strong domestic and global presence, the next step in the Company’s vision was to create a retail café.  In Spring 2015, David Rio opened the doors to Chai Bar by David Rio, a chai-centric café in San Francisco’s Mid-Market, so that locals and consumers from around the world could enjoy signature David Rio Chai products, as well as have the opportunity and excitement to share in David Rio’s newest offerings and products under

Ai Okubo | Chief Operating Officer

Ai was born in Japan, and spent her childhood between two worlds, in Tokyo, Japan and Portland, Oregon. Through this bi-cultural experience, Ai gained the appreciation of traditional food and beverage culture from Asia (including tea), and how the inspiration can transform when introduced into a western culture. After graduating from the University of Oregon with a degree in international business, Ai moved to the bay area, and joined David Rio in 2002 as the Customer Service and Operations Coordinator. Ai soon found passion in offering the best chai in the market to customers, and she became National Sales Manager in 2004. In 2005, Ai transitioned to Soma Beverage Company, a sister company of David Rio, as the International Sales & Operations Manager, where she gained expertise in production and quality assurance, as well as global sales and marketing initiatives. Ai returned to her roots at David Rio in 2008, and was later appointed Chief Operating Officer in 2015, overseeing the operations of the Company and its global markets in over 55 countries around the world. What Ai enjoys the most about David Rio is working with the people who believe in the brand and equally passionate about the animal welfare that has an impact to the environment today, as well as the future for the next generations to come. Today, Ai is a member of the Professional Business Woman of California (PBWC) and lives with her husband, Eric, and daughter, Emily (who came to work every day until she turned 1), in San Francisco. Ai enjoys growing organic vegetables and fruits in her garden, and playing bocce ball with family & friends in the backyard. Favorite Chai: Orca Spice Chai with almond milk, shot of espresso and boba prepared hot at David Rio Chai Bar.

Kiyoe Nakazawa | VP of Business Excellence

Kiyoe was born in the small village of Nagano, Japan, home to the world famous Snow Monkeys. Because her parents owned two Japanese restaurants, she was always interested in cooking and food culture, and enjoyed talking with customers. She was curious and creative and studied fashion and textile in college which came in very useful when she first started at David Rio. At the time, the fledgling company made everything in-house and Kiyoe put together banners and POS materials. Kiyoe always wanted to experience new cultures and life styles, so she began to study English at UC Extension in San Francisco where she met Rio, the co-founder of David Rio. She returned to Japan after living 1 -1/2 years in San Francisco to attend Culinary School to seriously study different cuisines and cooking. She received a chef's license in 1998 and volunteered as a chef at the Olympic Village during the 1998 Nagano Olympics. She enjoyed different environments and being able to speak English was very helpful. Kiyoe returned to San Francisco over 15 years ago and began working with Rio and Scott because she was enthusiastic about the passion for their business and products. Kiyoe has always enjoyed developing new products as well as improving existing products. Her standards are very high and she has continued to make operations more efficient by coordinating and meeting the deadlines for marketing and sales. David Rio has always promoted working mothers and their baby sitting needs. Kiyoe was able to bring her newborn son, Hiroki, to work after she returned from maternity leave. Hiroki "worked" and played at David Rio until he was one year old. He still enjoys visiting the office and Chai Bar, sampling the flavors and raw materials around his mother's desk. And he is very proud of the work his mother does for David Rio. Favorite Chai: C ub Chai Super Concentrate with 2% milk. She also liked Flamingo Vanilla Decaf Chai while she was pregnant.
