BEE-SPLAINING: What Causes Frosting in Honey?
Frosting is when tiny air bubbles or pockets appear between the honey and the jar in set and soft set honey. It is whitish in appearance and can look like a bloom, or a wavy pattern inside the glass. Frosting does not alter the taste of the honey but may be unsightly. The bubbles are there because they get trapped as the honey sets, and the air pockets are created as the sugars in the honey start to granulate.
Frosting frequently occurs in low moisture soft set honey, such as Oilseed r**e or Canola honey, which often have a moisture content of 14-16% when ripe. (‘Ordinary’ honey typically has a moisture content of about 17-20%.) Frosting happens regularly in this type of honey because the honey sets very quickly in the jar. It usually sets before the tiny air bubbles that were created when the honey was poured into the jar have risen to the surface, this is how the bubbles get ‘trapped’ in the honey and create frosting.
Frosting can also happen when honey granulates in the jar, predominantly in low-moisture honey, but also after some time in honey with a 17-19% moisture content. What you see then are tiny crystals, which usually start at the top of the jar and spread downwards, and you may also see little air pockets forming on the side of the granules.
Sometimes when frosting occurs, the honey also releases from the glass on the inside of the jar. If you are making soft set honey and want to avoid frosting, there are two things you should keep in mind: First is to make sure the moisture content of the honey is somewhere between 17-18%. If you are making soft set honey with low moisture honey, consider mixing it with a higher moisture honey to bring up the moisture content. Second is to take care when jarring and minimise the distance from honey gate to the jar. The shorter the honey has to travel the less air will go into the jar and less bubbles will be created. You can also warm the honey or the jars or both slightly to avoid bubbles forming near the glass.
It is important to draw attention to the fact that granulation (and frosting) is a natural and normal process in real honey, and not a sign that sugar has been added to it, as is a very common misconception. Most honeys will granulate naturally after some time. I often advise my customers to be wary not of honey that granulates, but of honey that does NOT granulate, as this can be a sign that the honey has either been tampered with or overheated, which unfortunately destroys some of the beneficial enzymes in honey.
