Have you ever walked into a bar or restaurant and seen a row of gleaming taps, each promising a different beverage? Maybe you’ve heard someone order a drink “on tap” and wondered exactly what that meant. While the phrase seems simple enough, there’s actually a lot that goes into understanding what it truly means for a drink to be “on tap.” It’s more than just pouring a drink from a spigot; it’s about the entire process, the quality, and the experience. Let’s delve into the world of draft drinks and uncover the nuances of what “on tap” really signifies.
The Basic Definition: Dispensing from a Keg
At its most fundamental, “on tap” simply means that a drink is dispensed from a keg using a pressurized system. Instead of individual bottles or cans, the beverage is stored in a large, often metal, container – the keg – and then pushed out through a faucet, or tap, by gas pressure. This is the core principle behind any drink served on tap, regardless of whether it’s beer, soda, wine, or even cocktails.
Kegs: The Heart of the System
Kegs are the unsung heroes of the on-tap experience. These sturdy containers are designed to withstand the pressure needed to dispense the beverage and protect it from contamination. They come in various sizes, from small pony kegs to full-sized barrels, and are typically made of stainless steel or aluminum. The material is chosen for its durability, sanitation, and ability to preserve the drink’s flavor.
Beyond just holding the liquid, kegs also play a role in keeping the beverage fresh. They are sealed to prevent air from getting in and oxidizing the drink, which can negatively impact the taste. The proper handling and storage of kegs are crucial for maintaining the quality of the beverage served on tap. Improperly stored kegs can lead to flat, stale, or even contaminated drinks.
The Tap System: From Keg to Glass
The tap system is the network of components that connects the keg to the faucet. This system includes the gas tank (usually CO2 or a mix of CO2 and nitrogen), the regulator (which controls the gas pressure), the beer lines (tubing that carries the beverage), and the faucet itself. Each component plays a vital role in delivering the perfect pour.
The type of gas used is particularly important. CO2 is commonly used for carbonated beverages like beer and soda, while nitrogen or a mix of gases is often used for stouts and other beers to create a smoother, creamier head. The pressure needs to be carefully regulated to prevent the drink from being over-carbonated or flat. The length and diameter of the beer lines also affect the flow rate and the overall quality of the pour.
Beyond Beer: A Variety of Drinks on Tap
While beer is the most common beverage associated with “on tap,” the concept has expanded significantly in recent years. Today, you can find a wide variety of drinks served on tap, catering to diverse tastes and preferences. This evolution has transformed the on-tap experience, making it more versatile and appealing to a broader audience.

What types of drinks are commonly served “on tap”?
Draft systems aren’t limited to just beer. While beer is the most commonly associated drink served “on tap,” many other beverages can be dispensed this way. Soda, wine, cocktails (pre-mixed or batched), coffee (both cold brew and nitro), and even kombucha are all finding their way into tap systems in bars, restaurants, and even homes.
The versatility of draft systems is increasing, allowing for creative and efficient beverage service. This diversification expands beyond just convenience, offering benefits like reduced waste from individual bottles and cans, precise portion control, and opportunities for unique flavor infusions and carbonation levels.
What are the key components of a typical “on tap” system?
A standard draft system consists of several crucial elements working together. These components include the pressurized container holding the beverage (keg, tank, or bag-in-box), a regulator to control gas pressure, the lines carrying the drink to the tap, the faucet (or tap handle) itself, and a gas source (typically CO2 or nitrogen) to propel the liquid.
Beyond these basics, other components can enhance the system. A cooler or refrigeration unit maintains the beverage’s temperature, ensuring optimal taste and preventing spoilage. A beer engine, used for cask ale, employs a manual pump instead of gas pressure. Regular cleaning and maintenance tools are essential for hygiene and proper function.
What are the advantages of serving drinks “on tap”?
Serving beverages on tap offers several significant advantages. Businesses benefit from reduced packaging waste, leading to lower disposal costs and a more environmentally friendly operation. Tap systems also provide efficient portion control, minimizing over-pouring and maximizing profit margins.
Customers appreciate the consistent quality and temperature of drinks dispensed from a draft system. Draft systems can often allow for larger volume purchases of beverages reducing the overall cost per serving to the business. The novelty and perceived freshness of drinks served “on tap” can also enhance the overall customer experience.
How does carbonation work in “on tap” systems?
Carbonation in tap systems typically relies on dissolving carbon dioxide (CO2) into the beverage under pressure. The higher the pressure, the more CO2 can dissolve, resulting in a more carbonated drink. The temperature of the beverage also plays a crucial role, as CO2 is more soluble in colder liquids.
Nitrogen (N2) is sometimes used in conjunction with CO2, particularly for stouts and other creamy beers. Nitrogen creates smaller bubbles, resulting in a smoother, creamier texture. Blending CO2 and N2 allows for precise control over the beer’s carbonation and overall mouthfeel.
What is “nitro” and how does it differ from traditional carbonation?
“Nitro” refers to a draft system that uses nitrogen gas instead of or alongside carbon dioxide for dispensing. The primary difference lies in the bubble size and resulting texture. Nitrogen creates much smaller bubbles than CO2, leading to a smoother, creamier mouthfeel.
Traditional CO2 carbonation produces larger, more prickly bubbles. Nitrogen, because of its lower solubility, doesn’t carbonate the liquid as much as it pushes the drink out of the keg, resulting in a smoother, less acidic beverage. This is why you often see nitro used with stouts and other beers where a creamy texture is desired.
What are common issues or problems encountered with “on tap” systems?
Several common issues can plague draft systems. Improper cleaning and maintenance are frequent culprits, leading to bacterial growth, off-flavors, and system malfunctions. Incorrect pressure settings can result in flat or overly foamy drinks.
Temperature fluctuations can also cause problems, affecting carbonation and flavor stability. Leaks in the system waste product and can create unsanitary conditions. Troubleshooting and regular maintenance are crucial for preventing these issues and ensuring optimal performance.
How often should an “on tap” system be cleaned?
The frequency of draft system cleaning depends on several factors, including the type of beverage being dispensed and the volume of use. As a general guideline, beer lines should be cleaned every two weeks, or more frequently if the beer is unfiltered or high in sugar content.
For other beverages like soda or wine, cleaning every month may be sufficient. However, it’s crucial to adhere to a strict cleaning schedule and use appropriate cleaning solutions to prevent the build-up of bacteria, yeast, and sediment, which can negatively impact taste and hygiene. Proper cleaning is vital for maintaining quality and extending the lifespan of the system.
