As a new beekeeper I was able to get about 20lbs of honey off my hive for the first time this year in August.
I put some of the honey in decorative glass bottles and some of it in your standard plastic honey bear bottles.
I then stored them all in a box in the kitchen pantry. When I took them out last week I noticed ALL the honey in the plastic bears has crystallized. They are cloudy, thicker and no longer opaque. ALL the honey in the glass bottles of similar size are still as clear as when bottled.
Given all the honey was from the same hive, extracted and bottled at the same time, filled to approximately the same levels, sealed (plastic bears has foil seals in the cap vs. glass bottles had either rubberized flip-top stoppers or metal lids), and stored under the same conditions.....Why do you think only the honey in the plastic bear containers has crystallized?
