Evolution of Beer Dispensers

Evolution of Beer Dispensers

Hollow reeds used for drinking beer in ancient times

Beer is one of the oldest beverages human kind ever produced. Brewing started back in fifth millennium BC in ancient Egypt and Mesopotamia, and was spread throughout world. Sumerians even had a beer goddess, Ninkasi. The first beers were home brewed. These beers were thick and had solids left from fermentation. People drank it by sucking it out of bowls and pots with hollow reeds (right).

At Middle ages, monastery brewhouses started to appear across Europe. When medieval monks in Europe started producing beer in large quantities, storage of beer became an issue. Putting beer into barrels then came into widespread practice. Originally, this was done to supply the monastery with a supply of beer for a given period. However, it became known to the general population that the monasteries had beer and the practice of the monks selling the beer became common.

Storage in barrels came with a better way to serve: Joseph Bramah’s  beer engine (right). Bramah was a British inventor who invented the beer engine. This engine was initially developed for pumping English style ale. As Americans’ taste switched from ale to lager, the engine started to become ineffective because it caused too much foaming. There arose a need for a new system that allow the beer to be served cold, maintain the carbonation in the beer and allow the beer to be poured without too much foam.

The brewers owned saloons and used their own proprietary dispensing mechanisms and storage systems. Some of the brewers adopted newly developed refrigeration systems while some still counted on good old ice. Over time, the beer was served at the saloon taps using compressed gas. This gas was typically air, which oxidized beer and made it taste stale. During this period, pasteurization of beer became common in order to allow quality to be maintained through shipping and delivery. Without brewery freshness and combined with poor dispensing and serving methods, draft beer fell out of favor and bottled beer became popular.

A Modern Draft Beer System from 20th Century

Recently the technology for serving draft beer was simplified by using pre-packaged, compressed carbon dioxide and draft beer started to make a comeback. In current draft beer systems, the keg hast two lines. One connected to the CO2 tank and one carrying the beer to the tap. The CO2 creates pressure and pushes beer to the tap, into the glass (left). There is also a cooling line right next to the beer line, which keeps beer cold through the line.

Nowadays we see a strong trend towards craft beer. 21st century consumers are looking for good quality beer together with new experiences. At Pubinno, we invented a revolutionary smart beer tap that serves 21st century beer to the 21st century consumers. Our plug&play and smart b
eer tap, monitors 10 parameters such as pressure, flow rate and temperature to serve the same perfect beer every time. Our smart flow algorithm and patent pending robotics make sure foaming is minimized also making sure bartenders can do necessary adjustments. Our cloud platform enables breweries and bars to track their operations and beer quality in real time. Welcome to the future of draft beer!
