Author’s bee yard alongside canola field. Honey produced here granulates quickly.
The American Bee Journal published a timely piece in their August issue. It just hit my mailbox. The article is about avoiding granulated honey in your extracting frames. It’s written by your favourite bee-blogger. Me.
I’m not going to repeat my article here because you can read the whole thing in the bee journal. If you don’t already subscribe to the ABJ, you should. It’s a great resource for beekeeping and bee science. You can see my article in the magazine, but I will paraphrase part of it because it’s an important topic.

Trouble: granulated comb
Granulation can be a big expensive problem for some beekeepers, but others never see combs of crystallized honey. Along north Florida’s Apalachicola River, beekeepers produce tupelo honey which almost never granulates. But in northern, dry regions of the plains and prairies, canola honey may crystallize in the hive a week after bees store it.
Most honey is between the extremes of canola and tupelo, crystallizing a few months after extracting. The primary causes of granulation are the honey’s glucose-to-moisture ratio, storage temperature, the passage of time, and purity of the honey. I cover these in detail in the American Bee Journal. Today, I will just give a summary of two points – moisture and glucose.

High-glucose honey – safely in a jar.
There are two main sugars in honey – fructose and glucose. They vary between species of honey plants. It’s the glucose that forms crystals. Just a little more glucose makes a big difference in granulation. Floral varieties high in glucose include canola, cotton, mesquite, and manzanita. Those with low glucose levels include tupelo, acacia (black locust), and sourwood. The low ones are slow to granulate.
Water is also important in this discussion. Think of honey as an unstable, supersaturated solution of just glucose and water. Glucose crystals precipitate if there is about one-and-a-half times more glucose than water in the honey. In other words, if your honey is 18% water, then 27% glucose is the cut-off. Very few types of honey have such low amounts of glucose. Average American honey is 31% glucose. Canola averages 36% while tupelo is just 25.6%. These numbers are similar in other parts of the world – most honey has enough glucose to crystallize if moisture is below 19%. (Honey over 19% is less likely to granulate, but it will sour and ferment.)
Here’s how this relates to your honey crop. You probably can’t avoid areas or crops with higher contents of glucose. You probably don’t want to – maybe that’s where you make most of your honey. But if you are in such an area, get the honey off the bees quickly (as long as it’s ‘cured’ or ‘ripe’ enough and below 18.6% water content. Then keep the boxes warm – combs granulate most rapidly at about 15 ºC (60 ºF). Finally, extract as quickly as possible – don’t let the boxes sit around for weeks, but get at ’em and get ’em done!
There is more to this story. Temperature and timeliness are important. And there’s something I call ‘purity’ in my article. This involves avoiding dust and old granulation crystals in the honey frames. These serve as starting points for new granulation. These things (and more) are included in my American Bee Journal piece. The bottom line is keep things clean and warm and get things done on time – the same advice you’d hear from any beekeeper.
Which honey will granulate? Those at the top of the graph are most likely to crystallize because of their higher glucose level. Moisture varies with region and local climate, lower moisture honey granulates more quickly than higher moisture honey.


















The elderberry honey which I purchased at Arlo’s Honey Farm in south-central BC was darker than golden, very thick, and had a rich – but not overwhelming – taste and scent. To me, it epitomizes what most people think honey should be. Not mild like my favourite (sweet clover) but not as powerful as buckwheat honey which (to me) is almost medicinal in potency. It’s great when gobbled by the spoonful, but also very nice when drizzled on fresh peaches and blueberries. I even touched up a salad with some of the extraordinary elderberry honey.
I am visiting Kelowna for a number of reasons, not least of which is to learn about beekeeping near deep blue Lake Okanagan. This area is nearly a desert, but the lake’s water, used for irrigation, has turned it into an oasis of peaches, apples, and increasingly, vineyards specializing in wine grapes. There are also beekeepers who make a bit of honey and help keep the fruits pollinated.
























Malathion is deadly stuff. Not so much to humans. For us, it’s relatively safe, though farm kids are cautioned not to eat it. Because malathion can be handled fairly carelessly, it was used a lot on farms in past decades. Insects are not so lucky. Malathion wiped out billions of honey bees over the years. Of course, it sometimes saved farm crops from hungry bugs and beetles and it
