I’ve dealt with bubbles and foam in honey many times, especially right after extraction and during bottling. The first time I saw it, I assumed something had gone wrong with my honey. Over time, I learned that bubbles are usually a normal side effect of handling raw honey, not a sign that it has spoiled or lost quality.
Most bubbles I see show up after spinning frames in the extractor or transferring honey between containers. In nearly every case, letting the honey settle and handling it more gently fixes the issue. Understanding what causes bubbles and when they actually matter takes a lot of unnecessary stress out of honey harvesting.
If you are seeing bubbles or foam in your honey, the good news is that this is usually cosmetic, easy to manage, and very common among beekeepers.
What Causes Bubbles in Honey?
Honey is a dynamic, living substance, especially when raw and minimally processed. Bubbles can form at several points during harvesting, extraction, and storage.
Air Introduced During Extraction
The most common cause of bubbles is air being mixed into the honey during extraction. When honey is spun out of the comb using an extractor, tiny air bubbles become suspended in the liquid. This happens more often when extractors are run at high speeds or when honey is thick and cool.
I notice this most when extracting large batches quickly. The honey often looks perfectly clear at first, then bubbles appear hours or even days later as the trapped air slowly rises to the surface.
Straining and Filtering
After extraction, honey is typically strained to remove wax, propolis, and debris. Pouring honey quickly through strainers or between containers can trap air inside the honey. In my experience, fast pours create far more bubbles than slow, controlled transfers.
Even when using fine mesh strainers, the way honey is poured matters more than the filter itself.
Stirring or Agitation
Honey does not respond well to agitation. Stirring, pumping, or aggressively mixing honey introduces air, especially when trying to liquefy partially crystallized honey. Even repeated movement of containers can introduce bubbles.
This is why honey that has been moved or bottled often develops bubbles afterward, even if it appeared clear initially.
Fermentation
Fermentation is far less common, but it is important to rule out. If honey has a moisture content above about 18 percent, wild yeast can begin fermenting sugars and producing carbon dioxide. This creates bubbles and foam that continue forming instead of settling out.
Fermented honey often smells sour or yeasty and may taste sharp or alcoholic. If you are unsure, moisture testing is critical. See What Is the Proper Moisture Content of Honey? for detailed guidance.
Temperature Changes
Temperature fluctuations also play a role. Warming honey makes it thinner, allowing trapped air to rise. Cooling honey can cause dissolved gases to come out of suspension and form visible bubbles.
This is why bubbles sometimes appear after honey is moved between rooms or stored in changing conditions.
Why Is There Foam in My Honey?
Foam is closely related to bubbles but tends to look more dramatic. It usually appears as a pale or white layer on the surface.
Natural Proteins, Enzymes, and Pollen
Raw honey naturally contains proteins, enzymes, and pollen. When air bubbles rise, they carry these particles to the surface, forming foam. I see this most often in lightly strained or unfiltered honey shortly after extraction.
This type of foam is harmless and does not affect taste, safety, or shelf life.
Fermentation Warning Signs
Foam combined with a sour smell or active bubbling can indicate fermentation. Unlike normal foam, fermentation foam often reappears after being skimmed and may increase over time.
If foam continues forming and the honey smells off, fermentation is likely occurring. At that point, the honey is better suited for fermentation projects like mead rather than long-term storage.
Recent Pouring or Bottling
Foam frequently appears right after bottling. When honey is poured quickly into jars, air is introduced and foam forms within hours. In most cases, this foam settles or can be skimmed off easily.
For best bottling practices, see The Beekeeper’s Guide to Bottling Honey.
Are Bubbles in Honey a Problem?
In most cases, bubbles in honey are not a problem at all.
Bubbles are usually cosmetic and do not affect flavor, nutrition, or safety. I routinely leave small bubbles in honey intended for personal use and even for sale, as long as the honey smells normal, tastes good, and tests within proper moisture levels.
Bubbles only become a concern when they are paired with signs of fermentation, such as persistent bubbling, sour odor, or rising foam that does not settle. Without those indicators, bubbles alone are not a quality issue.
Many experienced beekeepers accept a small amount of surface foam as normal, especially in raw, minimally processed honey.
How To Get Rid of Bubbles in Honey
If you prefer a clearer appearance, several reliable methods work well.
Let the Honey Settle
The simplest solution is patience. Let the honey sit undisturbed in a clean container for several days. Gravity does most of the work. Bubbles and foam rise naturally and can be skimmed off.
This is my default approach for small and medium batches.
Use a Warm Water Bath
Gently warming honey helps bubbles escape faster. Place the container in warm water no hotter than 100°F or 38°C for 15 to 30 minutes. The honey becomes less viscous, allowing air to rise more easily.
Avoid overheating, as excessive heat damages enzymes and aroma.
Skim the Foam
Once bubbles collect at the surface, skim them off with a clean spoon. This is fast, effective, and does not affect honey quality.
Use a Settling Tank
Larger operations often use settling tanks. Honey sits for several days, bubbles rise, and honey is drained from the bottom. This produces very clear honey with minimal handling.
Vacuum Defoaming
Vacuum defoaming removes air by lowering pressure inside a sealed chamber. This method is unnecessary for hobbyists but useful for commercial processors handling large volumes.
How to Prevent Bubbles and Foam in My Honey
Prevention comes down to slow, gentle handling.
Extract Gently
Avoid running extractors at full speed immediately. I always start slowly and increase speed gradually. This reduces air incorporation and protects comb.
Pour Slowly and Low
Pour honey close to the receiving surface instead of from a height. This single habit dramatically reduces bubbles.
Allow Honey to Rest Before Bottling
Whenever possible, let honey sit for several days before bottling. This allows bubbles to rise naturally and makes bottling much cleaner.
Maintain Stable Storage Temperatures
Store honey in a stable environment, ideally between 50°F and 70°F. Frequent temperature swings encourage bubbles and foam.
Control Moisture Content
Proper moisture control prevents fermentation-related bubbling. A refractometer is extremely useful here. See Best Refractometer for Honey if you regularly test moisture.
Common Questions About Bubbles in Honey
Many new beekeepers worry that bubbles mean something is wrong with their honey, but in most cases, bubbles are simply a sign that the honey was recently handled.
A common question is whether bubbles will disappear on their own. In my experience, most bubbles will rise to the surface and either settle out or form a thin foam layer within a few days if the honey is left undisturbed.
Another frequent concern is whether bubbles mean honey has gone bad. Bubbles alone are not a sign of spoilage. As long as the honey smells normal, tastes good, and does not continue producing gas, it is safe to consume and store.
Some people also wonder if bubbles affect nutrition. They do not. The nutritional value of honey remains the same whether bubbles are present or not.
Finally, it’s normal to see bubbles reappear after moving or pouring honey. Each time honey is disturbed, some air can be reintroduced, which is why patience is often the best solution.
Can I Sell or Gift Honey With Bubbles?
From a quality standpoint, honey with bubbles is perfectly acceptable to sell or gift, provided it is not fermenting. Many beekeepers, myself included, sell raw honey with minor surface bubbles, especially when the honey has been recently bottled.
That said, presentation matters. If you are selling honey at markets or gifting it, allowing jars to settle for several days before labeling and distributing them helps improve appearance. Skimming surface foam just before final presentation can make jars look clearer without altering the honey.
Educating customers also helps. I’ve found that explaining that bubbles are normal in raw honey often increases trust, especially with buyers who are specifically seeking minimally processed products.
Final Thoughts
Bubbles and foam in honey are a normal part of working with a raw, natural product. In most cases, they are purely cosmetic and easy to manage with patience and gentle handling.
Over time, I’ve learned that not every jar needs to look perfectly clear to be high quality honey. If your honey smells normal, tastes good, and tests within proper moisture levels, bubbles alone are nothing to worry about.
