So, since the weather here has been incredibly crazy and my2 baby hives seem to be light, i've starred feeding them. i've been making between 1:1 and 1.5:1. Tonite I was a batch and got distracted and it boiled for maybe 15-20 minutes. The syrup is still clear and not really that thick, but I know that if you overcook your syrup it can be bad for the bees. So, how long is too long? Love, Ziffa!
