I don't think it makes much difference, early this season I Demarree'd a couple of colonies using foundation purchased well before 2010 and which had been sat, unwrapped on a shelf in an outbuilding until the now long departed beekeeper's son gave it to me for disposal, the bees had drawn it all out within a weekAnd if kept wrapped will be fresher to get the bees working on it. ( I know some don't think it makes a difference)
I agree, I make my frames, including foundation, up during the winter and have used very old foundation (donated by the widow of a long departed beek) with no real problems. If I have a blowtorch with me when loading the frames into the hives I sometimes give them a quick blast to bring the oils to the surface.I don't think it makes much difference, early this season I Demarree'd a couple of colonies using foundation purchased well before 2010 and which had been sat, unwrapped on a shelf in an outbuilding until the now long departed beekeeper's son gave it to me for disposal, the bees had drawn it all out within a week
My bees are ok with old foundation too. Even the sheets with odd holes in themI don't think it makes much difference, early this season I Demarree'd a couple of colonies using foundation purchased well before 2010 and which had been sat, unwrapped on a shelf in an outbuilding until the now long departed beekeeper's son gave it to me for disposal, the bees had drawn it all out within a week
I run the blow torch over older wax foundation when I need to use it .I don't think it makes much difference, early this season I Demarree'd a couple of colonies using foundation purchased well before 2010 and which had been sat, unwrapped on a shelf in an outbuilding until the now long departed beekeeper's son gave it to me for disposal, the bees had drawn it all out within a week
I'm glad now I marked the frames with the ancient foundation in (there were some shallow as well as deeps) as I now can't tell the difference between them and the 'fresh' stuffMy bees are ok with old foundation too. Even the sheets with odd holes in them
It's almost the best thing about beekeeping... that smell.Whatever. Beekeeping. I just like the smell of fresh foundation. JBM is right, main problem is it is very brittle when cold. If it is a cold day in spring when I am putting in foundation I will do it indoors. I have messed up enough sheets in the past
