The work is focused on the analysis of data on sugar composition of honey coming from beekeepers in the Czech Republic. The database includes a number of years and several hundred locations. The aim is to test the hypothesis that sucrose content in honeys vary in individual years in connection with the course of the weather, especially the sufficiency or deficiency of rainfall, so that in rare cases it can even unadulterated honeys sucrose content exceed the limit specified standard. It will formulate recommendations for action at the findings of the high sucrose content of genuine honeys to prevent unauthorized punishment.
