Surplus and reserve

Honey in the hive is not one undifferentiated pile waiting for you, it splits into two piles with two different owners. Whatever sits in the brood box is the colony's winter reserve, and it stays there, untouched, no matter how full a frame looks in midsummer. Only the capped surplus stored above is yours to take.

In a colony's first year this matters even more than usual: nearly everything a new colony brings in goes toward drawing comb, rearing brood, and building the reserve it needs to survive its first winter, so a first-year colony typically has no real surplus to harvest at all.

Taking honey anyway, because it is there and tempting, is one of the most common ways a beginner starves a colony that had done everything right.
