Ringing of glasses.
The ringing of glasses is one of those times-honored traditions that everyone follows without even thinking. Some argue that originally this tradition was intended to drive away demons. Others believe that the idea was to spill a little wine from one glass in the drinking cup while chocanizing (so no one could poison each other without being poisoned himself). In fact, the reason is much more prosaic.
Even before the tradition of clinking glasses appeared, four senses were involved in the process of drinking wine: touch, taste, sight and smell. The hearing was not involved. When they began to produce glass glasses, then a tradition emerged, in which all kinds of feelings were introduced (a chime of the glass that caressed the rumor was added).
