What is drivert sugar and how can it be used for feeding bees? The Essential Guide to Dry Winter Bee Feed


Drivert sugar is a specialized, dry sugar formulation composed of sugar in a "more raw" state. Unlike standard granulated sugar, which often requires external moisture to be palatable or digestible for the colony, drivert sugar is designed so that bees can process and consume it directly in its dry form.

By eliminating the need for water, drivert sugar acts as a critical winter safety net, allowing you to provide emergency calories without introducing dangerous moisture into the hive during freezing temperatures.

The Unique Properties of Drivert Sugar

The "Raw" Advantage

Standard white sugar often requires processing or dissolution before bees can utilize it effectively. Drivert is manufactured to be in a more raw state.

This specific formulation bridges the gap between raw material and a food source the bees can immediately metabolize.

Consuming in Dry Form

The defining characteristic of this sugar is its ability to be processed from a dry form.

Bees can break down and consume this sugar without the beekeeper needing to mix it into a syrup. This makes it distinct from standard feeding methods that rely heavily on water-to-sugar ratios.

Strategic Application in Apiaries

The Winter Feeding Solution

The primary reference explicitly identifies drivert sugar as a tool for winter feeding.

During winter, liquid feeds can freeze or lower the temperature of the cluster. Drivert provides essential carbohydrates to keep the colony warm without the thermal penalty of consuming cold liquids.

Managing Hive Moisture

One of the greatest threats to bees in winter is condensation. Feeding liquid syrup introduces water that can condense on the inner cover and drip onto the cluster, killing the bees.

Because drivert is dry, it allows the colony to feed without increasing the humidity inside the hive.

Understanding the Trade-offs

Seasonal Specificity

Drivert is a specialized tool, not a universal replacement for all feeding.

While effective in winter, it is generally not the primary method for building up stores in the autumn. It is best viewed as a maintenance or emergency feed for cold weather survival.

Versus Liquid Syrup

It is important to distinguish between "feeding for storage" and "feeding for immediate survival."

Liquid syrups are typically used when the weather is warm enough for bees to cure and cap the liquid in the combs. Drivert is used when the weather is too cold for that process to occur.

Making the Right Choice for Your Goal

To select the correct feed, you must look at the calendar and your specific objective for the hive.

  • If your primary focus is Fall Preparation: Use a 2:1 sugar-to-water syrup. This heavy syrup is ideal for helping bees build up bulk food stores quickly after the final honey harvest.
  • If your primary focus is Winter Survival: Use drivert sugar. This provides accessible energy during cold months when the bees are clustered and cannot process liquid feed or handle excess moisture.

Use the right consistency at the right time to ensure your colony maintains the energy required to regulate its temperature.

Summary Table:

Feature Drivert Sugar Standard Liquid Syrup (2:1)
Primary Use Emergency Winter Feeding Fall Storage Preparation
Moisture Content Low (Dry Form) High (Liquid)
Bee Consumption Direct metabolic processing Must be cured and capped
Best Temperature Freezing / Cold Mild / Warm
Main Benefit Prevents hive condensation Rapidly builds bulk stores
