Listen carefully, because this might save you from the most common mistake in beekeeping: harvesting honey from a first-year colony. Do not do it. I know the temptation is almost unbearable — you have watched your bees all spring and summer, filling frames with liquid gold, capping cells with pristine white wax. Surely, you think, surely I can take just a little?
No. Leave it all. Every drop. First-year colonies need every ounce of honey they produce to survive their first winter. Take it from them, and you sentence them to starvation or, at best, a desperate scramble requiring emergency feeding in February. This is the First-Year Rule, and it is inviolate.
For established colonies — those that have survived at least one winter — the calculus changes. Now we can discuss harvest. But even then, the question is not "Can I take honey?" but rather "Should I take honey, and if so, how much?"
Before you even think about extracting, assess whether your colony is truly ready. Walk through this checklist:
1. The colony survived winter and built up strongly in spring. A colony that barely limped through winter and is still rebuilding population in July is not ready to share. Let them keep their stores.
2. The brood boxes are full. In a standard Langstroth setup, this means two deep boxes (or three mediums) packed with brood, pollen, and honey. The bees' living quarters should be thriving before you start pillaging the pantry.
3. The honey super is at least 70-80% capped. This is the magic number. Capped honey has been evaporated to roughly 18% moisture or less — low enough to resist fermentation. Uncapped honey is still "wet," and if you extract it, it will ferment in your jars within weeks, turning to alcoholic slop.
The shake test: Pull a frame from the super and give it a sharp, downward shake. If uncapped nectar slings out, the honey is not ready. If nothing drips, it is dry enough to harvest. This is not as precise as a refractometer (a tool that measures moisture content), but it is faster and costs nothing.
4. Timing is right. Harvest after the main nectar flow but before you need to prepare for winter. In most temperate climates, this means late July through early September. Waiting too long means dealing with fall feeding, which can interfere with extraction. Harvesting too early means the bees have not yet finished curing the honey.
A colony needs substantial honey reserves to survive winter. How much depends on your climate:
How do you estimate weight without disassembling the hive? The two-finger lift test: place two fingers under the hive's rear handle and try to lift the back of the hive an inch off the ground. If you can barely budge it, the hive is heavy with honey. If it lifts easily, stores are light.
A deep frame fully loaded with capped honey weighs about 8-10 pounds. Do the math. If your two brood boxes need to contain 70 pounds of honey for winter, and each deep holds ten frames, you are looking at roughly seven to eight full frames of honey just for winter stores. If your super contains surplus beyond that, then you can harvest.
"The beekeeper who takes too much honey in August will be feeding sugar syrup in March, wondering where he went wrong."

There are situations where the answer is simply, unequivocally, no:
The colony is weak or undersized. A small population cannot defend large honey stores and may be robbed. They also cannot consume and process enough food to build reserves. Help them first, harvest later.
Varroa mite counts are high. A colony battling mites is under stress. Do not add starvation to the equation. Treat for mites, then reassess.
The queen is failing or missing. A queenless colony or one with a failing queen is in crisis mode. Let them keep their honey while they raise a new queen or until you can requeen them.
The nectar flow ended early. If drought, frost, or other factors cut the flow short, your bees may not have had time to build surplus. What looks like extra honey may be all they have.
You have any doubt. When in doubt, leave the honey. You can always take some next year. You cannot un-starve a colony.
Geography dictates timing. In the northern United States and Canada, the harvest window is narrow — late July to mid-August, before colonies begin their fall prep. In the South, you might harvest twice: once in early summer after the spring flow, and again in fall after the goldenrod.
Some regions have distinct flows: clover in June, basswood in July, goldenrod in September. If you want varietals — honey from a single source — you must harvest between flows, when the super contains predominantly one type of nectar. Miss the window, and it all blends.
New beekeepers often think in terms of "my honey" versus "their honey." This is backwards. It is all their honey. You are merely borrowing the surplus, and only if they can afford to lend it. The moment you forget this, you become a honey thief, not a beekeeper.
If your colony produces 100 pounds of honey and needs 70 pounds for winter, you get 30 pounds. Not 50. Not "just a little more." Thirty. And if you are uncertain whether they need 70 or 80 pounds, assume 80. Generosity to your bees is repaid in thriving colonies. Greed is repaid in deadouts.
