Улей Николая Витвицкого удивляет. Абсолютно противоположный подход к зимовке.

Information about the wintering in the hive of Nikolay Vitvitsky for reflection.
As a rule, beekeepers try to cut a nest when preparing a bee family for wintering, remove excess cases, put warm shutters on both sides of the nest, insulate the nest on the outside, cover the hive from the outside, and also ensure that the ventilation in the hive is good.
In the hive of St. Nicholas of Witwicki there is no such thing.
In my opinion, the key to a successful wintering in the hive of Nikolai Vitvitsky is a large internal hive volume compared to the volume of the nest itself. The volume of the nest can be several times less than the total volume of the hive.
Due to the large internal area of the hive, the humidity from the nest is distributed to the entire internal volume of the hive and all the inner walls of the hive, thereby reducing the humidity in the nest itself.
And also, thanks to the large internal area of the entire hive, this humidity condenses in the winter on the walls of the hive and gradually outward through the walls.
And also, thanks to the large internal area of the entire hive, it is possible to "breathe" the hive, to pass a sufficient amount of oxygen through the microcracks and micropores in the walls of the hive.
This information can be taken into account by beekeepers during the formation of their hives of any design for the winter.
