About Kéan Coffee

Kéan Coffee™ is the modern evolution of a long time tradition by coffeehouse pioneer Martin Diedrich of providing the community with vibrant meeting places in which to enjoy the highest quality fresh roasted coffees on the planet. As original direct trade coffee roasters, we craft roast our carefully selected coffees from around the globe onsite daily, procured from small holder farmers many whom we have had longstanding personal relationships with since the 1970s. Roasting our coffees onsite daily means your coffee has often been roasted within hours of the moment it reaches your cup. Our expertly trained baristas craft your coffee beverages to the highest standards.

Martin, founder of the Diedrich Coffee chain, left behind the corporate environment his family business had become to return to his roots as an independent coffeehouse operator and micro roaster, and his ideals of what a coffeehouse and coffee culture should be. Martin together with wife Karen put a lifetime of creativity, inspiration and deep coffee experience into bringing Kean Coffee to life. Martin and Karen Diedrich aptly named this next generation of coffeehouse after their son, Kean.

In addition to our seasonally rotating selection of single origin coffees from every coffee growing region, Kéan Coffee also features an outstanding selection of organic loose-leaf hot and iced teas, as well as exquisite non-coffee beverages like single origin sipping chocolates. Our pastries and savories are baked fresh daily by small local artisan bakeries, including scrumptious gluten-free and vegan options. Come and enjoy our warm, community atmosphere in the true coffeehouse tradition!

Martin Diedrich

Martin Diedrich grew up in Guatemala where his family owned a small coffee farm. In 1983, Martin left behind a blossoming career in Mayan archeology and came to Costa Mesa to help his parents with their small family coffee roastery. During that year his vision emerged to create community meeting places where people could gather and enjoy his family's exquisite farm-direct coffees.

Martin founded the first Diedrich coffeehouse in Costa Mesa in 1984. Diedrich Coffee grew to nearly a dozen locations over the next ten years. These original coffeehouses were exciting, innovative hives of activity and became the most popular gathering places in their respective neighborhoods, and an iconic landmark in the Orange County landscape.

In September of 1996, Diedrich Coffee went public, quickly growing to more than thirty Diedrich Coffee locations in California, Colorado and Texas. Martin is now considered one of the pioneers of the American coffeehouse phenomenon. An internationally recognized coffee expert, he has been a Master Roaster for more than three decades.

In 2005 Martin was presented with the Specialty Coffee Association's Lifetime Achievement Award - previously bestowed on a handful of coffee luminaries including Starbucks founder Jerry Baldwin, Alfred Peet, George Howell, and Dr. Ernesto Illy.

In June of 2004 Martin resigned his position at Diedrich Coffee and began to manifest a new vision for a modern coffeehouse that would bring back the community feeling, coffee connoisseurship, and cultural atmosphere of his early Diedrich coffeehouses, as well as embrace his ideal that businesses should model community and global responsibility and awareness. Martin and Karen Diedrich opened the doors of Kéan Coffee in Newport Beach, California in December of 2005, named for their only son, Kean.

Just a stone’s throw from the first location where Martin had originally joined his parents Carl and Inga, Kéan Coffee quickly developed a loyal following of regulars both old and new. Through Kéan Coffee, the Diedrich family is taking Martin’s community coffeehouse vision to the next level.

Karen Diedrich

Karen Varese Diedrich

Karen Varese Diedrich brings her own eclectic array of business experience to Kéan Coffee™. Karen began working in local restaurants at age fourteen. When Martin and Karen met in 1994 she was working with the iconic Fahrenheit 451 bookstore/coffeehouse in Laguna Beach handling their PR, writing the monthly newsletter and coordinating entertainment, book signings and events for the coffeehouse.

After earning a bachelor’s degree in Communications and a certificate in Design, Karen worked as a fashion designer in Los Angeles for four years before going on to complete her master’s degree in Clinical Psychology. All those years of schooling meant…of course…many hours spent in coffeehouses.

Karen is also a professional Middle Eastern dance performer and instructor and has been in the entertainment business for over twenty years. As an Italian immigrant who grew up with the traditional daily espresso, Karen brings her own passion for coffee to Kéan Coffee™ and is very much in her element as a coffeehouse operator.

The Diedrich Family Legacy

Carl Diedrich For Martin Diedrich, great coffee has been part of the family for several generations. The Diedrich family's coffee heritage began in 1916 when his grandmother Charlotte Diedrich inherited a coffee plantation in Costa Rica. Her son Carl Diedrich, Martin’s father, eventually followed in his mother's footsteps, and in the late 1940s learned the craft of coffee roasting while working for a roast master in the old city quarter of Naples, Italy. Then in the 1950s, Carl married Inga, whose family had been coffee, tea, and cocoa merchants in Germany since the turn of the 19th century. Carl and Inga purchased a small coffee farm in the 1960s in the Antigua region of Guatemala, renowned as one of the world's greatest coffee growing regions. There, Martin and his brothers worked the farm and developed both a love of coffee growing and a firsthand respect for the back-breaking work it takes to grow truly excellent coffee.


Lake Atitlan, Guatemala As coffee farm owners for much of the last century, the Diedrich family developed a deep, intuitive understanding of coffee. They came to a profound appreciation of the impact of climate and geography on coffee. Through their own experimentation and learning from others, they developed numerous techniques of growing, processing, and roasting to maximize coffee bean quality and flavor. This passionate and deep understanding of the coffee growing process was passed from Carl Diedrich to his son Martin, who took the baton and ran with it.

Martin on the farm in Antigua The Diedrich family began California operations in 1972 by importing, roasting, and retailing coffee from the Diedrich Guatemalan farm. Carl was roasting his coffee on a roaster that he had designed and built with his own hands. From 1972 to 1982, Carl would drive in his 1962 VW van the 3000 mile round trip from California through Mexico to Guatemala and back four to five times a year. While in Guatemala, he managed the business of the farm and on each return trip he brought back a vanload of sixteen 154-pound sacks of raw green coffee. Carl was a one-man, vertically integrated business.

In 1982, in the midst of severe political and economic turmoil in Guatemala, the Diedrich family’s Antigua coffee farm was seized. By this time Carl and his coffee roasting operation “Carl Diedrich and Sons” had already become a local favorite in Orange County. In 1983, Martin began taking over the retail, roasting, and importing facets of the family business. Martin founded the first Diedrich Coffee, a neighborhood coffeehouse, in 1984. Today Martin is considered one of the pioneers of the coffeehouse movement in the United States.

Martin Diedrich, 1985 Martin's concept for Diedrich Coffee was to create a community gathering place where people could enjoy a great cup of coffee with friends and neighbors in an atmosphere that promoted coffee knowledge and had a local vibe. These original coffeehouses were exciting, innovative, creative and cozy. This proved to be phenomenally successful and prompted Martin to grow and expand. By 1991, Martin had built the company's fourth coffeehouse in Orange County. His success allowed him to attract a more sophisticated management team to raise capital, and by 1996 the company had expanded to more than twelve Diedrich Coffee coffeehouses in Orange County and San Diego. After the company went public, expansion continued, and Diedrich Coffee bought several other coffee chains, bringing the company to international status with locations numbering in the hundreds.


Kean Diedrich, 2006 The Diedrich Family legacy also includes recognition as one of the world's top five manufacturers of coffee roasting machines. Carl Diedrich invented and hand-built his first roaster on the Guatemala farm in the 1960's. His purpose was to build a roaster specifically designed to custom roast the very fine grade of coffee he was growing. His philosophy of roasting was considered near heresy at the time but is now widely regarded as the best way to roast high quality coffees. Carl's original coffee roaster was the inspiration for Martin's brother Stephan Diedrich. Stephan vastly improved Carl's original concept utilizing state-of-the-art technology and engineering. He created Diedrich Manufacturing, a separate business from Diedrich Coffee, building top notch coffee roasting machines.

Today there are well over 2,500 Diedrich roasters operating in more than 50 countries worldwide. With the launch of Kean Coffee in 2005 as a coffee roaster-retailer in Orange County, the Diedrich family coffee legacy continues.

Community Values

We have long held to our belief that businesses bear a responsibility to model practices and support causes that promote the greater well-being of our local and global community. We start with our coffee purchasing, by seeking out coffees that are Certified Organic or grown using organic methods, without pesticides that harm the environment or our bodies.

Our direct trade relationships and frequent trips to origin enable us to witness firsthand the farming practices used to grow our coffees, and to engage in dialogue with the farmers as they implement new coffee farming innovations and worker benefit programs. The Fair-Trade certified coffees and teas we select promote healthy environments for workers, and our Rainforest Alliance certified products protect our vanishing rainforests.

Even for coffees that are not certified (the certifications cost the farmers considerable expense), we pay sustainable prices for all of the coffees that we purchase in order to support farmers ability to provide a fair livelihood for their workers.

We place high priority on managing our waste stream, from recycling every plastic milk jug and cardboard box to recycling the newspapers left at the coffeehouse. Virtually all our spent coffee grounds and roaster chaff are saved and happily used by our guests as wonderful soil amendment for their gardens. We save every burlap sack from the hundreds of bags of green coffee we roast monthly, donating them to individuals, schools, or local farms that can apply them to a variety of useful purposes.

We serve beverages in our coffeehouse in ceramic cups and glasses and offer to-go guests a ten-cent incentive to cut down on paper and plastic waste by bringing their own cups and mugs. Our hot cup sleeves are made from recycled paper and we reduce disposable plastics in our environment by encouraging our patrons to “skip the straw and lid” on cold drinks whenever possible. We are always seeking more ways to further our eco-conscious efforts, and to be an example to others to do the same.

We offer organic milk along with multiple non-dairy options, organically grown teas and many other organic products, choosing organic whenever possible.

While we are passionate about implementing every sustainable practice possible in-house, our involvement goes far beyond our coffeehouse and wholesale roastery doors. Martin has been a featured presenter at many Zero Waste conferences, environmental awareness symposiums and university events and has been an invited guest on decision-making panels to discuss affecting positive change on environmental policies.In 2007 Kéan Coffee was recognized as a "Zero Waste" business by Earth Resource Foundation, and in 2009 Kéan Coffee was named by the OC Metro as one of Orange County's "Green 15" for its dedication to operating Kéan Coffee with a focus on sustainability.

Along with our regular involvement with and donations to local and national conservation groups, these combined efforts speak to our dedication to practicing responsible stewardship towards the health of our community and our environment, and we hope that we can continue to inspire others to do the same.
