This song relates to the times of which there were often temperance movements to wipe out the production and use of alcoholic beverages.
One must understand that drunkeness was an onogin problem. Most people (peasants) could not read or write, thus they (the masses) could be a political threat. They were always hungry, with scurvay and usually drunk.

It was considered a serious vice of the peasants and as such could be a threat to the power (feudal lords)and the King.

Only noblemen should have the rights and power of such brew.
