Unfiltered Honey: Nature’s Golden Elixir

Unfiltered honey, nature’s golden elixir, has been cherished for centuries for its delightful taste, numerous health benefits, and versatile uses. However, a common process in raw honey—crystallisation—often raises questions among honey enthusiasts.

Does real honey crystallise, and if so, why?

Many people mistakenly consider crystallised honey to be spoiled or think there is sugar added to it. But let’s dive into the science behind honey crystallisation, explore factors influencing this process, and learn how you can navigate this natural occurrence in raw honey.

Honey Crystallisation: A Natural Process

Honey crystallisation is a natural process that occurs in raw honey, during which the honey changes its consistency from liquid to solid. This process does not indicate spoilage or adulteration. Crystallised honey is just as good as runny honey, and the change in consistency does not affect its quality.

Why Does Honey Crystallise?

Honey contains natural sugars—fructose (fruit sugar), glucose (grape sugar), and water. Depending on the type of honey, the sugar content ranges from 30-44% fructose, 25-40% glucose, and around 20% water. The higher sugar content means the water in honey contains more sugar than it can naturally hold.

When glucose crystallises and separates from the water, it forms crystals. As this process progresses, more glucose crystallises, spreading through the honey and changing its consistency.

Factors Affecting Crystallisation in Honey

  • Type of Honey
    The floral source from which bees produce honey significantly affects crystallisation. Honey with higher glucose content is more prone to crystallisation. For example, unfiltered honey tends to crystallise quickly due to its high glucose levels, whereas filtered honey crystallises more slowly.
  • Filtration
    Pollen in honey contributes to crystallisation. Tiny bits of pollen and other natural substances found in unprocessed honey provide platforms for crystals to begin forming. These elements speed up crystallisation, which is why they are often filtered out during the pasteurisation of most commercial honey.
  • Storage Temperature
    Lower temperatures encourage crystallisation. Storing honey in the fridge or a cold pantry often results in crystallisation. In contrast, higher temperatures delay this process.
    Optimal Storage: Honey is best stored at room temperature (around 18°C-21°C or 64°F-70°F) to maintain its liquid state longer. Keep it away from direct sunlight, as exposure to light can degrade the honey’s quality over time.
  • How to De-Crystallise Honey

    If your honey has crystallised but you prefer it runny, don’t worry! You can easily turn crystallised honey back to a liquid form:

  • Place the jar of honey in a bowl of warm water.
  • Cover the jar with a towel and let it sit for a few hours.
  • Periodically top up the hot water to maintain a high temperature, around 45°C (113°F).
  • The actual temperature the honey will be exposed to is probably around 30-35°C (86°F-95°F), similar to what honey experiences in the hive on a summer day. This method preserves the honey's taste and beneficial properties.

    Note: This method is recommended only for honey stored in glass jars, as some plastic containers may react in hot water.

    Why Unfiltered Honey is More Likely to Crystallise

    Unfiltered honey has not been heat-treated or filtered, retaining its natural state, including pollen. As a result, it is more likely to crystallise over time compared to most commercial honey, which undergoes heat treatment and filtration.

    Commercial honey is often processed to meet the quantity and price demands of mass-market sales. However, unfiltered honey has a natural tendency to crystallise over time—a sign of its raw, unprocessed quality.

    In Conclusion

    Unfiltered honey tends to crystallise over time, and this is a natural process that indicates quality and rawness. Not all types of honey crystallise the same way or at the same speed.

    The factors explored—floral source, temperature, and storage conditions—all affect the speed and extent of crystallisation. Whether you prefer the smooth texture of liquid honey or the grainy texture of crystallised honey, both are equally delicious and versatile.

    If you wish to de-crystallise honey, gently warming it in a glass jar is the best method, but avoid using microwaves or boiling water. Ultimately, whether you choose liquid or crystallised honey is a personal preference. As long as the honey is raw and natural, it offers numerous benefits.

    Frequently Asked Questions (FAQs)

    1. Does real honey crystallise?
    Yes, real honey crystallises. It is a natural process and does not mean the honey has gone bad or been adulterated.

    2. Why does honey crystallise?
    Honey crystallises due to its high glucose content. As glucose separates from the water in honey, it forms crystals, changing the honey’s consistency.

    3. Is crystallised honey safe to eat?
    Absolutely! Crystallised honey is just as safe and nutritious as liquid honey. The crystallisation process does not affect its quality or taste.

    4. How do I de-crystallise honey?
    To return crystallised honey to a liquid state, place the jar in warm water (around 45°C or 113°F) for a few hours. Avoid using microwaves or boiling water to preserve the honey’s natural properties.

    5.Does unfiltered honey crystallise faster than filtered honey?
    Yes, unfiltered honey tends to crystallise faster because it contains natural particles like pollen, which speed up the crystallisation process.
