HONEY, HONESTLY.
Real questions. Straight answers about honey.
Why does honey crystallize?
Honey naturally contains mainly glucose and fructose. Over time, some of the glucose can separate from the liquid and form crystals. How quickly this happens depends on factors including the honey’s natural sugar balance, moisture content, floral source and storage temperature.
Raw or minimally processed honey can crystallize more readily because naturally occurring pollen, tiny wax particles and existing sugar crystals can provide starting points for crystals to form. Cooler temperatures can also encourage crystallization. Crystallization is a natural process and does not mean your honey has gone bad.
Prefer it liquid? Place the closed container in warm water and allow it to warm gently until the crystals dissolve. Avoid excessive heat, which can affect some of honey’s heat-sensitive components.
Does crystallization mean sugar was added to my honey?
No. Crystallization does not mean sugar has been added to honey. Honey naturally contains sugars—primarily glucose and fructose—and it is the natural glucose that can form crystals over time.
Adding sugar or sugar syrup to honey is a different issue called adulteration. Honey may be adulterated by mixing it with cheaper sweeteners such as high-fructose corn syrup, corn syrup, rice syrup, cane/invert sugar syrup or other commercial syrups and selling the mixture as pure honey. You cannot determine whether honey is adulterated simply by whether it crystallizes; proper authentication may require laboratory testing.
Why is some honey processed to stay clear and liquid?
Honey may be commercially processed to improve clarity, delay crystallization and extend shelf stability. Fine filtration can remove pollen and other tiny particles, while heating or pasteurization can dissolve existing crystals and reduce naturally occurring yeasts.
There can be a trade-off. Intensive filtration can remove naturally occurring pollen, while heat treatment can reduce the activity of some natural enzymes and affect some of the naturally occurring plant compounds that contribute to honey’s antioxidant properties. How much is affected depends on the processing method, temperature and duration of heating.
Why does my honey have bubbles?
A few small bubbles in honey are often simply air trapped during extraction, pouring or bottling. Because honey is thick, those bubbles can take time to rise to the surface. Warmer temperatures make honey less viscous, so trapped air may move through it and become more noticeable.
Persistent bubbling or foaming accompanied by a sour or alcoholic smell is different and may indicate fermentation, particularly when the honey’s moisture content is high.
How can I tell if my honey is genuine?
There is no simple home test that can conclusively prove honey is genuine. Popular internet methods such as the water test, flame test, thumb test, or judging honey solely by thickness or crystallization should not be treated as proof. Honey authentication can require laboratory analysis using validated methods to examine its sugars and other chemical characteristics.
Why is my honey darker or lighter than the last bottle?
Natural honey varies in colour. One of the biggest influences is its botanical origin—the flowers and plants from which the bees collected nectar. Season, geography, age and storage can also contribute to differences. Genuine honey from different harvests therefore does not necessarily look identical from bottle to bottle.
Why does my honey sometimes taste different?
The plants visited by bees influence honey’s aroma and flavour. Different nectar sources contain different compounds, so changes in flowering plants, location and season can naturally produce differences in flavour and aroma between harvests.
Does darker honey mean better honey?
Not necessarily. Different botanical sources naturally produce honey with different colours and chemical characteristics. Some darker honeys have been found to contain higher levels of certain naturally occurring plant compounds and antioxidant activity, but colour alone cannot tell you whether honey is genuine or whether one honey is universally “better” than another.
How should I store my honey?
Keep honey tightly sealed in a clean container in a dry place away from excessive heat and direct sunlight. Storage conditions can affect honey’s colour, flavour, enzyme activity and crystallization. A change in texture—particularly crystallization—doesn’t automatically mean the honey has spoiled.
Does honey expire?
Honey is naturally resistant to spoilage because of its low water activity, high sugar concentration and acidity, which make it difficult for many microorganisms to grow. That doesn’t mean storage is irrelevant. Honey can undergo changes in colour, flavour, aroma and other quality characteristics over time, particularly when exposed to heat or moisture.
