Manuka honey is produced in New Zealand and Australia, but New Zealand claims the manuka honey trademark. Australia says that's not fair. They want to use it, too.
Manuka is to honey what Château Cheval Blanc 1947 is to wine connoisseurs. Buy a bottle of that wine and you'll fork over $304,375. Buy an eight-ounce jar of manuka honey and you'll lighten your wallet by $1790.
Bees make manuka honey from Leptospermum scoparium, also known as "The New Zealand tea tree" or more accurately, "bush." The honey prized for its health benefits, including its antibacterial and antifungal properties and anti-inflammation qualities.
According to webmd.com, "The major antibacterial component in manuka honey is methylglyoxal (MG). MG is a compound found in most types of honey, but usually only in small quantities. In manuka honey, MG comes from the conversion of another compound, dihydroxyacetone, that is found in high concentration in the nectar of manuka flowers."
"The higher the concentration of MG, the stronger the antibiotic effect. Honey producers have a scale for rating the potency of manuka honey. The rating is called UMF, which stands for Unique Manuka Factor. The UMF rating reflects the concentration of MG. To be considered potent enough to be therapeutic, manuka honey needs a minimum rating of 10 UMF. Honey at or above that level is marketed as UMF Manuka Honey or Active Manuka Honey.
reports that New Zealand's honey producers have long argued that it's the only country that can produce true manuka honey, because it's the only place where the manuka bush (Leptospermum scoparium) is found. Australian manuka, they argue, comes from other different-but-related species. (The New Zealanders have previously suggested that the Australian version should be called tea tree honey.)
recently wrote in Wine and Food: "The New York TimesManuka honey? Tea tree honey?
Well, we just think of the bees and that beautiful plant.
For five years, we grew a Leptospermum scoparium keatleyi, the tallest and rangiest variety of the Leptospermum scopariums. It bears our family name, Keatley; New Zealand sea skipper/horticulturist Capt. Edward John "Ted" Keatley (1875-1962) discovered it and named the variety "keatleyi."
Factoids: According to the Maritime Museum in Wellington, New Zealand, Capt. Keatley once commanded 28 of the Northern Steam Ship Company's vessels. He also was considered an authority on the flora of the Auckland province. In June 1961, the Royal Horticulture Society awarded Capt. Keatley the "Award of Merit" for his discovery of the keatleyi, or "royal pink manuka."
Sadly our "Keatley" plant didn't make it past five years. But generations of honey bees nectared on the blossoms while the plant thrived in our yard.- Author: Kathy Keatley Garvey
Or you can do taste, discuss and analyze that honey during the Sensory Evaluation of Honey Course, hosted Nov. 7-9 by the UC Davis Honey and Pollination Center in the Robert Mondavi Institute (RMI) on Old Davis Road, UC Davis campus.
The three-day certificate course covers "everything in the world of honey," says director Amina Harris. It takes place from 9 a.m. to 5 p.m. each day in the RMI Sensory Building. Yes, there's still time to register; a few openings remain.
"Attendees will taste, discuss and analyze approximately 40 varieties of honey from across the globe to hearing the latest in bee sting allergy research," according to the center's press release. "The focus is on tasting honey using both the well-known Italian method taught at the Registry of Experts in Bologna alongside our own UC Davis research tasting protocols and techniques."
Course instructors include:
- Orietta Gianjorio, professional taster of honey certified by the Italian Register of Experts (she also professionally tastes wine, olive oil, chocolate and other commodities)
- Suzanne Teuber, M.D., a UC Davis professor in the Department of Medicine, who focuses on allergies
- Amy Myrdal Miller, a national consulting nutritionist
- Joyce Schlachter, a quality control specialist at Crockett Honey with a direct interest in adulteration
- Mani Niall, a professional chef,, occasional beekeeper and author of “Covered in Honey" and
- Hildegarde Heymann, a world-renowned professor of sensory science, who will explain exactly how our sensory apparatus works.
The introductory course uses sensory evaluation tools and methods to educate participants in the nuances of varietal honey, Harris said. Students will learn about methods of evaluation, stands and quality in this certificate program. It's geared for anyone interested in learning how to critically taste and assess honey. Using standard sensory techniques, packers, chefs, beekeepers, writers, food manufacturers, honey aficionados will learn about the nuances of varietal honey.
Attendees will receive a UC Davis Honey Flavor Wheel and the Center's newly published Honey Journal, in addition to access to all presentations.
Another highlight: members of the UC Davis research team will share results from their honey analysis research. The research includes work in the field of gas chromatography, Nuclear Magnetic Resonance (NMR), pollen and the development of a full sensory panel.
Like to register? The fee for the three-day certificate course is $799. For more information, access Sensory Evaluation of Honey or contact Amina Harris at aharris@ucdavis.edu.

"You can learn a lot from these displays," a fairgoer at the 144th annual Dixon May Fair commented.
She was looking at an educational display with the catchy title, "None of Your Beeswax," the work of Ryan Anenson of the Tremont 4-H Club, Dixon, whose projects include beekeeping. The display is showcased in the Youth Building (Denverton Hall) at the Dixon May Fair, which opened Thursday, May 9 and continues through Sunday, May 12.
In his project, Anenson explained what bees produce. He zeroed in on bee venom, pollen, beeswax, royal jelly, honey, propolis, and also alternative medicine, history of honey, and bee hive air. Anenson concluded: "Honey might be the most well-known bee product in the world, but it certainly isn't the only by-product these magnificent creatures produce. Bees are considered 'the pillars of agriculture' for the work they do in pollination. If you have ever enjoyed most fruit, vegetables and other crops, you should generally thank the bees. Through pollination, bees contribute to maintaining biological balance in nature and help various animal and plant species, including humans, to thrive. Honeybee products are an entirely natural food source and have a long medicinal history that people have used since ancient times.Bees are arguable the most invaluable species to life on earth and are more vital than many people may realize."
As for beeswax, Anenson penned: "Worker bees at a young age will secrete beeswax from a series of glands on their abdomens. They use this beeswax to form the walls and caps of the honeycomb. However, some beekeepers use plastic as a foundation or substitute for honeycomb. Just like the honey that bees produce, many people harvest beeswax for various purposes, like candles, lip balms, creams, polish and conditioners, just to name a few."
The teenage 4-H'er was among those who attended a UC Davis Bee Symposium several years ago, and also participated in a recent California Honey Festival, co-sponsored by the City of Woodland and the UC Davis Honey and Pollination Center.
Madeline Giron, another Dixon 4-H'er, sketched a color pencil drawing of a bee, and Markus Taliaferro of the Suisun Valley 4-H Club, Dixon, submitted a photo of a honey bee sipping nectar. Another drawing, the work of Katelyn Nipper of Fairfield, featured "crayon art flowers": brightly colored spring flowers bordered by the crayons she used.
Lots of flowers! Just add pollinators!
Meanwhile, speaking of pollinators and plants, there's a clearance plant sale at UC Davis on Saturday, May 11 at the UC Davis Arboretum and Public Garden's Teaching Nursery on Garrod Drive. It's open to the public from 9 a.m. to 1 p.m. Horticulturists are billing it as a "Pollinator Paradise." Everything is 15 percent off (Members receive an additional 10 percent off.) You can access the inventory here.

So says beekeeper/journalist Kim Flottum, who has served as the editor of Bee Culture magazine for more than three decades.
Flottum will speak on "So You Want to Be a Beekeeper" at the third annual California Honey Festival on Saturday, May 4 in downtown Woodland, and it's a talk you won't want to miss. He'll speak at 11:30 a.m. on the UC Davis Educational Stage. Admission to the fair is free.
Also in his talk, he'll clue you in on "where to get information, what can go wrong and what can go right," and then you can ask questions.
We asked Flottum why folks should keep bees. They "provide essential pollination, improve the genetics of the wild bee population in the area, ensure native plant populations," he said, "and because there is absolutely nothing more calming, soothing, enjoyable than being a part of that civilization, right in your backyard."
Agreed!
We remember when Flottum, who lives in northeast Ohio, addressed the Western Apicultural Society's 40th annual conference, held in 2017 at UC Davis. He predicted that the nation's 250,000 beekeepers (who manage around 4 million colonies) will turn into a million beekeepers in five years.
Flottum applauded "the incredible rise of new beekeepers in the last 10 years." He launched the magazine BEEKeeping, Your First Three Years, several years ago.
Beekeepers are becoming more and more diverse, specializing in honey production, pollination services and queen bee breeding. Pollination services and queen bee breeding are the most profitable, Flottum said. Honey, not so much.
"If I'm in beekeeping, pollination services is sure bet," he said. "Beekeepers now get 200 bucks a colony for almond pollination in California. Pollination is more profitable than honey. Bee breeding? Queens can sell for as much as $40 or $50."
"In the United States, we eat on the average 1.2 pounds a year, but in Canada, it's 2.5 or 2.4 pounds." He lamented that unsafe and/or questionable honey from China floods our nation's supermarkets and is being sold at undercut prices. (Some statistics indicate that a "third or more of all the honey consumed in the U.S. is likely to have been smuggled in from China and may be tainted with illegal antibiotics and heavy metals"--Food Safety News.)
It's important for American beekeepers to label their honey "Made in America" or localize it by city or state, he said.
Flottum also touched on such issues as honey bee health, nutrition, loss of habitat, poor quality forage, and pesticides.
The varroa mite/virus is the No. 1 problem for beekeepers, he said. "Other stresses include nutrition, nosema, pesticides...All of these can be fixed with money, increased diversity of bee stock, and a move way from both ag and in-hive legal and illegal chemicals."
The California Honey Festival, sponsored by the City of Woodland the UC Davis Honey and Pollination Center, will include scores of activities, from honey tasting to live music. Among the events: a cooking stage, the UC Davis educational stage, a kids' zone, a refreshment zone (beer and mead, which is honey wine) and live entertainment. (See the schedule)

Amina Harris, director of the Honey and Pollination Center, said that Kitty Bolte, the first speaker on the UC Davis Educational Stage, will welcome Woodand as a "Bee City." Plans also call for UC Davis to be named "Bee University" on Saturday, Harris said. "Rachel Davis, director of the Gateway Gardens, Arboretum has been spearheading this designation."
Master beekeepers in the California Master Beekeeper Program, directed by Extension apiculturist Elina Niño, will share information on bees and beekeeping throughout the festival. Bernardo Niño is the educational supervisor, and Wendy Mather serves as the program manager.
The Häagen-Dazs Honey Bee Haven will feature a pollinator garden installation highlighting what and how to plant for pollinators, along with displays about common bees found in gardens, according to Christine Casey, academic program management officer who manages the bee garden on Bee Biology Road, west of the central campus.
Launched in 2017, the festival aims to cultivate an interest in beekeeping, and to educate the public in support of bees and their keepers, according Harris. Last year's festival drew 30,000 people and some 16 California honey companies.
The California Honey Festival's mission: to promote honey, honey bees and their products, and beekeeping. Through lectures and demonstrations, the crowd can learn about bees and how to keep them healthy. Issues facing the bees include pests, pesticides, diseases, malnutrition, and climate changes.
As it expands from year to year, with more speakers, vendors, entertainment and family-friendly activities, the California Honey Festival is the place to "bee."
