The invention of refrigeration changed what (and how) we drink forever. After all, what’s a good glass of milk to you without a fridge? Before the refrigerator, it was common practice to keep food and drinks cool with things like chilly streams, stockpiled ice or snow, and later, ice boxes, which became popular in the 19th century. Various vapor-compression and gas-absorption refrigeration systems soon followed, but German engineer Carl von Linde is often credited with developing the first modern-style refrigerator, which he patented in 1877. The first electric home refrigerator was sold around 1915, and by 1920, there were some 200 models on the market. Refrigeration has changed the way drinks are packed and shipped, and of course the way we shop and drink.
