As a rule, sugar and water are mixed in a 3:2 ratio or, less frequently, on a 1:1 basis. This sugar is chemically identical to the sucrose contained in nectar and honeydew, the raw materials of honey. From a correctly made sugar water solution, bees get the necessary enzymes and can make good use of the sucrose as a nutrient. Preparing a sugar water solution is always time-consuming. Attention must be paid to the microbiological instability of the feed, which limits its shelf life and thus the length of time the sugar solution can be used. As a result, the solution must often be prepared in small batches.
