Extracted honey was put into half gallon clean jars in July 2008. Looked fine. Used fine filter. In Dec 2008 retrieved a jar from basement storage to find granulation. Heated to handle granulation. After heating, when poured a thick foam eventually forms on surface. The taste is OK but nothing to win a blue ribbon. Granulation is not unusual for this area of GA.
What's the cause of this foam? Never had this problem in my many, many years keeping bees. Thanks, Shoal Creek
