Where did caveman put his beer before the refrigerator was invented?
The cold beer phenomenon is an invention of the Wild West at a time when competition between establishments was fierce enough that one owner would shoot the other to put him out of busniness. Some drinkers were very loyal to certain saloons. Saloon owners were always looking to for ways to draw patrons away from their competitors, they would always try a new gimmick or two like player pianos, primitive jukeboxes, live entertainment. Cold beer at that time was something no one had even thought of and the concept was considered a real novelty that no one had ever tried before. The first saloon who had this idea (cant remember names) was able to take away so much patronage from his competitors that he was in fear of his life. To make the beer cold, bar tenders would have ICE sent in via locomotive from colder regions in the north. Then brought to the tavern by horse and carriage. Also worth noting, primitive forms of ammonia based refrigeration were just becoming available for use on ship
