Success stories
From dead-outs to colonies that make it through winter
Primal Bee began with two beekeepers who lost their colonies three winters running. The hive they engineered now holds a steady climate through the cold, and the field numbers show what that does for a colony.
Standard hive in winter
≈ 66 lb (30 kg)
Stores a colony burns just to hold brood temperature
Primal Bee®
≈ 13 lb (6 kg)
Winter stores consumed in controlled field testing
It started with two friends who kept losing their bees
Alessandro Gamberoni and Gianmario Riganti met in high school and never stopped adventuring together, climbing, skiing, and trading notes on whatever they were building. When they took up beekeeping as a way to spend more time outdoors, they ran into the same wall every beekeeper knows too well: for three years straight, they lost their colonies.
A hidden world inside a cedar tree
A fellow beekeeper invited them to observe a large established colony inside a hollow cedar. The observation prompted a question about how enclosure geometry and thermal conditions affect a colony. Primal Bee's eventual answer was engineered and measured, not an attempt to imitate the cavity.
Bees are thermally sensitive — the box was fighting them
Over more than a decade of development, Alessandro and Gianmario investigated how hive heat transfer, brood geometry, spacing, sealing, and entrance placement affect the environment a colony must regulate. Traditional equipment solved many practical needs; Primal Bee adds thermodynamic performance as another design variable.
A hive engineered around the bee, not the box
Their patented answer is engineered, not imitated: high-density EPS walls, a vertical sealed brood chamber, and adiabatic sealing that hold a stable thermal environment. Field-tested from Alaska to the Negev desert, the colonies finally did what they're built to do — grow, store, and survive winter.
Today that work ships as the Primal Bee Hive: a complete thermodynamic system patented in the US, EU, Australia, and Canada. Controlled tests and attributed field reports document specific outcomes under specific conditions; forage, weather, genetics, queen quality, mites, timing, health, and management still shape every colony. Read the full story.
The winter math, measured
The story matters because of where the numbers landed. Every figure here is documented on the science page, tied to a method and a comparison.
Primal Bee versus standard-hive stores consumed in one controlled comparison (6 kg versus 30 kg). The result measures that comparison, not a guaranteed overwintering outcome.
Full-system insulation, from an R-140 top cover to the sealed nest walls, holding the cluster's heat through winter instead of leaking it to the weather.
Why the winter numbers move
A sealed, insulated envelope reduces uncontrolled heat exchange and can help manage where moisture condenses. Overwintering still depends on mites, colony strength, stores, queen quality, weather, ventilation strategy, and beekeeper preparation.
2017 Swiss field comparison
Primal Bee reports a 2017 comparison involving Primal Bee and standard Dadant hives with Swiss institutional and beekeeper-inspector participation. The underlying report remains the authority for protocol and outcome details.
What the redesign actually delivers
These figures come from controlled comparisons, field trials, or development records. They are not universal forecasts; conditions and beekeeper management remain material.
Honey production vs. a standard hive
Colony size through faster brood growth
Less maintenance and hive intervention

The same hive, two very different wins
The thermodynamics don't change. What changes is what they buy you — peace of mind for a first colony, or margin and labor for a hundred.
For hobbyists
A more forgiving start, even while you're still learning.
- A bigger margin for error. Colonies begin from a lower energy burden, so a small mistake is less likely to cost you the hive.
- Better odds through winter. A sealed, insulated envelope keeps condensation off the cluster and bees burn far less honey holding temperature.
- Less to manage. Eight purpose-built brood frames instead of twenty-plus, and you can read the colony without tearing it apart to find the queen.
- Around 70% fewer inspections and interventions, so the hobby stays a hobby.
For sideliners & commercial operators
Fewer dead-outs and stronger buildup on the same footprint.
- Roughly 2x colony size and 2x honey under comparable conditions in field trials, from faster brood growth and less honey burned on heat.
- Fewer winter dead-outs and stronger spring buildup, so more colonies are productive earlier in the season.
- Up to 70% less maintenance and intervention, freeing labor across the operation.
- Supers take standard Langstroth medium and deep frames, so your extractor and harvest workflow stay exactly the same.
We're honest about the roadmap: the system isn't yet optimized for 300+ hive nomadic operations. If that's you, let's talk about where it fits today.

The Primal Bee hive is one of the most natural designs I’ve seen
The Primal Bee hive is one of the most natural designs I’ve seen—closely reflecting what bees prefer in the wild. In my work studying condensing colonies, I’ve looked at how to balance heat, humidity, and airflow in ways that support, rather than stress, the bees. This system handles those factors with impressive efficiency, and it comes closer than most hive designs to what bees might create for themselves.

Nearly 100 pounds in the first season
Just ordered 6 more. I too didn't believe the claims when I bought two hives. Had to start with no comb and a package because of the frame design. I live in a northern climate with a short season. I installed the package in May. By the end of that first season, they had built out everything with tons of stores, and I had harvested almost 100 pounds from the supers.

She observed faster spring buildup
A significantly enhanced colony development dynamic was observed by me both in early spring and following queen confinement during the active season—well above the performance typical of standard hives. The colony demonstrates improved efficiency in feed resource management. Hive inspections using the Primal Bee frame system are streamlined and operationally efficient.

I was skeptical at first, but the data doesn’t lie.
I was skeptical at first, but the data doesn’t lie. I’ve tested every type of hive, each with broodminder sensors. Primal Bee is the only hive in my apiary still putting on weight during a nasty dearth. The temperature and humidity stay remarkably stable, and the build is incredibly solid. Extraction is simple with standard supers, and the team’s support has been the best I’ve experienced in beekeeping.

Honey production exceeded what I thought was possible!
This hive created the best conditions for my colonies to maximize their potential. The honey production exceeded what I thought was possible.
