What is a Draught System?

A draught system, also known as a draft system, is a system used to dispense beverages, typically beer, from a keg or cask. It is commonly found in bars, restaurants, and breweries where beer is served on tap. The draught system ensures that the beer is poured at the correct temperature, carbonation level, and with the right amount of foam.

How does a Draught System work?

A draught system works by using a combination of gas pressure and specialized equipment to push the beer from the keg to the tap. The beer is stored in a keg or cask, which is connected to a series of tubes and valves that lead to the tap. Gas, usually carbon dioxide or a mixture of carbon dioxide and nitrogen, is used to pressurize the keg and push the beer through the lines.

When the tap is opened, the gas pressure forces the beer out of the keg and through the lines, where it is dispensed into a glass or mug. The flow of beer is controlled by the tap handle, which opens and closes a valve in the system. The beer is poured into the glass with the right amount of foam to enhance the flavor and aroma of the beer.

What are the components of a Draught System?

A typical draught system consists of several key components, including:
– Keg or cask: where the beer is stored
– Gas cylinder: provides the pressure to push the beer through the lines
– Regulator: controls the pressure of the gas
– Coupler: connects the keg to the gas and beer lines
– Beer lines: tubes that transport the beer from the keg to the tap
– Faucet/tap: where the beer is dispensed
– Drip tray: catches any spills or drips
– Cleaning equipment: used to maintain the cleanliness of the system

These components work together to ensure that the beer is dispensed properly and that the system remains clean and functioning correctly.

What are the different types of Draught Systems?

There are several different types of draught systems, each with its own unique features and benefits. Some common types include:
– Direct-draw system: the most basic type of draught system, where the keg is stored directly below the tap
– Long-draw system: used for longer distances between the keg and the tap, typically found in larger establishments
– Glycol-cooled system: uses a glycol cooling system to keep the beer at the correct temperature, ideal for serving multiple beers at once
– Nitro system: uses a mixture of nitrogen and carbon dioxide to dispense beer, resulting in a creamier texture and smoother taste

Each type of draught system has its own advantages and is suited to different types of establishments and beer styles.

How to properly maintain a Draught System?

Proper maintenance of a draught system is essential to ensure that the beer is dispensed correctly and that the system remains clean and sanitary. Some key maintenance tasks include:
– Regular cleaning of the lines and equipment to prevent buildup of bacteria and mold
– Checking and adjusting the gas pressure to ensure the beer is dispensed at the correct rate
– Inspecting and replacing any worn or damaged components, such as seals or valves
– Keeping the system at the correct temperature to prevent the beer from becoming too warm or too cold

By following a regular maintenance schedule and keeping the system clean and well-maintained, you can ensure that your draught system continues to dispense high-quality beer.

What are the benefits of using a Draught System for serving beer?

There are several benefits to using a draught system for serving beer, including:
– Fresher taste: beer served on tap is typically fresher and more flavorful than bottled beer
– Consistent quality: a properly maintained draught system ensures that the beer is dispensed at the correct temperature, carbonation level, and foam
– Cost-effective: serving beer on tap can be more cost-effective than serving bottled beer, especially for high-volume establishments
– Environmental benefits: using a draught system reduces the need for single-use bottles and cans, making it a more sustainable option

Overall, a draught system offers a convenient and efficient way to serve beer, providing a better experience for both customers and establishments.
