For the past several years I have been making my sugar syrup on a weight basis and it seems to work well. Some formulas for volume adjust the volume of water slightly above the equivalent volume of sugar to get a 1:1 ratio in weight. Our bee association (WCBA) no longer gets a good pricing deal on sugar so we are looking at karo syrup but have to get such large volumes and have to store it warm that it looks as though we will need heated stainless steel containers in the 2000 gallon range. Anybody have a good piece of information on corn syrups and bees,or on proper storage.
