What causes honey to spoil?

Honey has natural antibacterial and antimicrobial properties that allow it to resist spoilage and last for decades if stored properly. However, there are a few factors that can cause honey to spoil:

Exposure to heat or sunlight: Excessive heat can destroy enzymes and antioxidants in honey. Sunlight can trigger chemical changes that degrade honey.

Absorption of moisture: Too much moisture from the environment can lower honey’s sugar concentration, providing an environment for yeast and fungi to grow.
Crystallization: Natural crystallization does not spoil honey but can make it grainy or thick. But moisture-triggered crystallization can lead to fermentation.
Yeast contamination: Yeast spores in the air or from bees can grow in honey, causing it to spoil through fermentation.

How to store honey to avoid spoilage

Proper storage is key to preventing honey from spoiling. Here are some tips:

Store in a cool, dry place: Ideal temperature is between 50°F to 70°F out of direct sunlight.
Use an airtight container: Prevent moisture absorption and contamination by using an airtight glass, plastic, or ceramic container.

Never add water: Added moisture encourages fermentation and spoilage.
Never store at room temperature: The higher temperature causes honey to lose antibacterial properties faster.
Refrigerate crystallized honey: Cold temperature (not freezing) keeps crystals small and uniform in texture.

Signs that indicate spoiled honey

Watch out for these common signs that suggest your honey has spoiled:

Change in texture: Fresh honey is fluid, creamy, and smooth. Spoiled honey becomes foamy, extra thick or partially solid.
Change in aroma: Fresh honey smells floral with hints of beeswax. Old honey smells fermented, stale, or moldy.

Change in taste: Fresh honey is sweet and aromatic. Spoiled honey tastes odd, bitter, too sweet, or like alcohol.
Change in appearance: Fresh honey ranges from light to dark but is translucent. Spoiled honey appears cloudy, opaque, or has surface mold.
Air bubbles: Tiny air bubbles throughout honey indicate fermentation and spoilage.

Crystal formation: Coarse, gritty crystals can be a sign of moisture-induced spoilage.
Foam: Frothy foam on the honey’s surface is a sign of fermentation.
White film: Solid whitish film on the surface indicates mold growth.

How to check honey for safety

Here are some methods to help determine if your honey is safe to eat or needs to be discarded:

Look: Examine the honey’s appearance. Fresh honey looks creamy and translucent. Discard crystallized or cloudy honey.
Smell: Note any odd or fermented odors. Fresh honey smells floral with sweet, fruity undertones.

Taste a small amount: Fresh honey dissolves smoothly, leaving a sweet taste. Discard fermented, bitter, or odd-tasting honey.
Monitor consistency: The texture of unspoiled honey is thick and creamy. Fermented honey can be foamy or partially solid.
Pay attention to best-by date: For processed honey, the best-by date indicates safety. Discard honey past this date.

Check for air bubbles: Gently turn the jar over. Bubbles indicate unwanted fermentation.

What to do if honey shows signs of spoilage

If your honey shows any signs of going bad, it’s best to throw it out. Spoiled honey can make you sick. Do not eat honey that is:

Crystallized into a hard, partially solid texture

Cloudy instead of translucent
Grainy or coarse, with large crystals
Excessively foamy or bubbling

Covered with white film or spots of mold
Smells odd, fermented, or unpleasant
Tastes bitter, too sweet, or strange

Safely discard bad honey in a sealed container so it does not attract insects. Wash any utensils, containers, or surfaces exposed to spoiled honey.

Does honey ever truly expire?

Well-stored honey has an indefinite shelf life and may remain safe to eat for decades. However, honey can lose quality, aroma, texture, and flavor over time. Signs of aging include:

Darkening color – honey naturally darkens with age as flavor compounds like caramelize

Loss of aroma – fresh honey has a pronounced aroma while old honey smells flat
Crystallization – natural process but can affect texture
Change in taste – older honey can lack complexity of flavor

Loss of nutrients – some enzymes and antioxidants degrade over time

So while properly stored honey does not truly expire, its quality and flavor can diminish over the years. Most honey remains appetizing for 2-5 years if stored airtight in a cool location. However, honey may become unsuitable for consumption eventually due to long-term chemical changes.

Tips for checking honey freshness

Here are some quick tips to evaluate the freshness and quality of your honey:

Verify creamy, smooth texture – thick and spreadable
Check aroma – fresh, floral scent
Taste a small amount – sweet, no odd aftertaste

Examine color – bright, light-to-dark shade based on floral source
Look for translucent appearance – not cloudy or opaque
Check bottle date if labeled – consume within 2 years for peak quality

Evaluate crystallization – fine uniform crystals are okay

If your honey exhibits any traits like bad aroma, strange taste, foamy bubbles, partial solidification, or mold growth, it should be discarded.

How to revive crystallized honey

Natural crystallization does not harm honey but alters its texture. You can liquify solidified honey by:

Placing the honey jar in warm water – heat to 104°F to liquify crystals
Storing in a warm area – around 70°F helps resolve minor crystallization
Using a food dehydrator – dehydrate at the lowest temperature setting

Leaving in hot car – warm temperature restores fluidity

Do not microwave honey or place in boiling water, as this can destroy beneficial compounds and flavors. Also avoid adding liquids like water, which dilute honey. After restoring fluidity, store honey in an airtight container in a cool, dry place.

Types of honey that resist crystallization

Some honey varietals are less prone to natural crystallization. These slow-to-crystallize honeys include:

Acacia
Blueberry
Lavender

Rosemary
Sourwood
Tupelo

Their high fructose-to-glucose ratio keeps them flowing freely. They crystallize at a slower rate due to:

Low glucose levels – glucose forms crystals as it separates from water
High fructose content – greater solubility means slower crystallization

Higher water concentration – more moisture content prevents crystallization
Prevalence of fine pollen grains – particles hinder glucose crystal formation

So when buying honey, you can look for these varieties to get one that stays liquid longer if crystallization is a concern.

Uses for crystallized honey

While crystallized honey may not have the best texture for drizzling or spreading, the honey is still perfectly safe for eating. Some uses for solidified honey include:

Baking – adds sweetness to cakes, cookies, breads
Smoothies – sweetens and thickens blended drinks

Yogurt – mix into yogurt or fruit parfaits
Oatmeal – flavor enhancer for oats
Tea or coffee – mix into hot drinks instead of sugar

Candy making – useful as a binder in snacks like granola bars

The granular texture also makes crystallized honey easy to measure in recipes. Simply scoop out the desired amount.

What to substitute for spoiled honey

If you need to toss out spoiled honey, suitable substitutes include:

Maple syrup – For a cup of honey, use 3/4 cup maple syrup. Reduce liquids slightly to account for maple syrup’s higher moisture content.
Brown rice syrup – Substitute 1 cup honey with 1 cup rice syrup. Add a pinch of lemon or orange for flavor.
Agave nectar – Replace 1 cup honey with 2/3 cup agave. Reduce liquids to compensate for the extra moisture.

Molasses – Use 1 cup molasses for every 1 cup honey. Combine with a bit of maple syrup to balance the intense flavor.
Corn syrup – Substitute 1 cup honey with 1 cup corn syrup. Expect a less complex, more one-note sweetness.

Adjust any substitution amounts as needed depending on the specific recipe and your taste preferences.

Storing honey after opening

To maintain freshness after opening your honey, follow these guidelines:

Transfer to an airtight glass or plastic container – prevents moisture absorption and contamination
Push out air from the container before sealing – minimizes oxidation

Store in a cool, dry spot – around 60°F to 70°F is optimal
Keep away from direct light – prevents degradation from UV rays
Use clean, dry utensils – reduces the introduction of moisture or impurities

Use within 1-2 years for best quality – flavor and aroma diminish over time

With proper storage, honey can stay fresh for many months after opening. Refrigeration is not required but can help slowed crystallization.

Signs of fermentation in honey

Small amounts of yeast naturally occur in honey. Too much moisture or warmth creates conditions for excessive yeast growth and fermentation. Signs your honey is fermenting include:

Air bubbles or foam – carbon dioxide released from yeast activity
Liquids leaking – watery separation of honey and yeast
Expansion in container – carbon dioxide takes up more space

Pressurized lid – gas buildup increases internal pressure
Cloudy appearance – particles suspended due to movement from gases
Alcoholic smell – ethanol and carbon dioxide are byproducts of fermentation
Vinegar-like smell – some yeasts produce acetic acid during anaerobic fermentation

Fizzy sensation – carbonation when tasted
Increased tartness – acids produced by yeasts

Discard any honey that shows signs of fermenting, as it can contain high alcohol levels along with undesirable tastes.

Storing homemade creamed honey

Creamed honey, also called spun honey or churned honey, has a smooth, spreadable consistency created by introducing fine crystals into liquid honey. To maintain the texture of creamed honey:

Use clean, sterile equipment – prevents microbial contamination

Allow to fully crystallize – minimum 2 weeks for complete crystallization
Store at 55-57°F – cooler temperature prevents liquefication
Keep in airtight container – prevents moisture loss or absorption

Refrigerate after opening – cold temperature maintains consistency

Properly stored creamed honey maintains its creamy texture for several months. If it does liquefy, it can be re-whipped in a stand mixer.

Conclusion

With its antibacterial properties and low moisture content, well-stored honey has an indefinite shelf life. However, honey can show signs of spoilage if it is exposed to unfavorable conditions like excess moisture, heat, yeasts or molds. To check if your honey has spoiled, examine its appearance, aroma, texture and taste. Discard any honey that shows signs of fermentation like air bubbles, cloudiness, crystals or off smells. Storing honey in an airtight container in a cool, dry place maximizes its freshness and quality over time. Properly handled, delicious honey can last for decades without going bad.
