How it works

Weigh both ingredients.

Ratios mean sugar : water by weight. A 2:1 mix contains two parts sugar for every one part water. For a 6 kg batch, weigh 4 kg of sugar and 2 kg of water. Ingredient weights add up to batch weight; this does not calculate finished syrup volume.

Useful to know

Is 1:1 measured by weight or volume?

This calculator always uses weight. A 1:1 batch contains equal weights of sugar and water. Cups of sugar and water do not weigh the same; use scales for both ingredients.

Which ratio should I choose?

1:1 is a lighter syrup; 2:1 is a more concentrated syrup. Choose a recipe appropriate to your colonies, weather and local feeding guidance. The calculator works out a recipe, not how much food a colony needs. Avoid feeding syrup while collecting honey for harvest.

Can I start with the sugar I already have?

Yes. Select Sugar available and enter its weight. The result gives the water to add and the total batch weight. The per-hive figure simply divides that batch equally between the number of hives you enter.
