Refill kegs have been on the market for a very long time. These come in unique configurations and are produced using various materials to serve specific users' needs. Below is a rundown of some popular refillable keg types.
These are often the go-to choice since they are durable, corrosion-resistant, and offer excellent protection for the contents inside. They come in multiple sizes and are frequently employed in professional settings, including breweries, pubs, and restaurants.
These typically weigh much less than their steel counterparts and are more affordable. These are perfect for those who want disposable containers to fill beer, cider, or soft drinks.
These are much smaller than the standard ones, measuring around four liters. They are ideal for personal use or small gatherings and are compatible with home draft systems.
Short for "cornsylvania" kegs, these were traditionally used in soda distribution systems. They are 19 liters, constructed from stainless steel, and popular among home brewers for their simple connections and ability to hold pressure. They are excellent for those who want to experiment with homebrewing and dispensing systems.
These kegs are designed to maintain carbonation in beverages like sparkling wines, cocktails, or even cold brew coffee. The system allows the user to dispense the liquid without exposing it to oxygen, which can flatten the drink over time.
Each keg type is suited to different brewing and serving needs, whether for a large commercial brewery or a homebrewing enthusiast.
The refill keg design is based on various functional and aesthetic features that make them practical for storage, transportation, and serving. Below are the various parts that constitute the design of kegs.
Kegs have varying capacities depending on their volume. While most are in liters, they range from 5 liters to over 50 liters. Their size determines their usage - larger ones work best in big commercial enterprises, while smaller ones suit home use or miniature bars.
Kegs are mostly made of stainless steel due to its resistance to corrosion, peer strength, and ability to maintain the temperature and carbonation of the contents. Plastic kegs offer lighter, more affordable alternatives but are often less durable.
These play a vital role in a keg's operation. They help in the supply of carbon dioxide or air, enabling efficient beer dispensing. Different kegs use unique types of connectors, which are compatible with only some types of draft systems. This ensures safety and proper functionality. The varied disconnect types are also designed to work with specific beverages.
Gaps and seals are mostly designed using rubber or silicone to ensure the keg remains airtight. A good seal prevents oxygen from entering the keg, which could affect the drink's quality through oxidation. Silicone seals are more heat-resistant and last longer than their rubber counterparts.
Close Keg Taps can be a manual, lever, or commercial electronic tap. These are important as they allow the release of the contents while ensuring the keg remains under pressure. The draft quality is influenced by the tap choice and its installation.
In some kegs, the inside is coated with special materials to enhance the beverage's flavor, especially acidic drinks like cider or wine. Coatings prevent metal leaching and safeguard the drink's purity.
These are utilized in various industries, especially and for good reason. They offer a cost-effective, eco-friendly, and practical means to store and transport a wide range of liquids, from alcoholic beverages to chemicals. Below are some of the examples of places where kegs are commonly used.
Some of the best refill kegs are typically and exclusively designed for breweries to transport freshly brewed beer. They ensure the beer remains carbonated, and protected from light and oxygen, which is detrimental to quality.
In these two popular refill keg usage scenarios, they are used to serve draft beer, wines, and other carbonated beverages. They are compatible with the brewery's return shipment or can be sourced directly from suppliers.
They are an increasingly popular choice for wine storage and transportation. They are used to fill wines, especially ones in the larger kegs, to dispense wine in a more sustainable form.
Kegs refill distilled spirits like whiskey, vodka, and gin. They store and age spirits, especially in wood-lined and larger kegs where the spirit interacts with the wood to gain flavors.
Refill Kegs are growing in popularity among the home brewing community. They offer a convenient way to store and dispense homemade beers, ciders, and other beverages while maintaining proper carbonation.
Kegs can hold large volumes of beverages for events like weddings, festivals, or corporate functions. They are practical for transporting and serving drinks like beer and lemonade in one go.
In bars and restaurants, these kegs provide a backup solution to avoid running empty on a normally used beverage. These kegs can be pre-filled and kept in storage, ready to replace the main dispense kegs when empty.
Here's a detailed overview of the various types of kegs, their specifications, benefits, and maintenance tips.
Size
The most common refill keg sizes are 5, 10, 20, and 30 liters, usually preferred in larger breweries and industries. Larger kegs are more economical regarding refilling frequency, but due to their size, they may be more challenging to handle and transport.
Material
Stainless steel kegs are typically the most durable and most hygienic option available. They resist corrosion, last long, and are easy to clean. Plastic kegs, too, weigh much less than the steel ones, but they are not as durable.
Valves and Connectors
The keg has to be compatible with the existing dispense system. Various kegs use unique valve configurations. Ensure to use the appropriate gas and liquid disconnects for that specific keg type.
Pressure Rating
The pressure rating indicates how much internal pressure the keg can safely hold. It is especially important for carbonated beverages like beer. Make sure the refill keg can hold the pressure required by the beverage.
Cleaning
This should happen immediately after the keg has been emptied. A cleaning solution should be put in the keg and left to soak for a while. Its interior will be cleaned up and preserved for the next use.
Inspection
Refill kegs should be inspected regularly for any signs of damage. These include dents, rust, or leaks. Ensure to check all the valves and connectors for leaks, too. Any damaged keg can affect performance and compromise safety.
Pressure Testing
This is an important part of the standard maintenance of a refill keg. All kegs should be tested to their maximum pressure, which is the refill keg's ability to hold pressure. This will ensure that no kegs will explode or meet any disaster when filled with carbonated drinks.
Seals and Gaskets
These are the most common problems faced by keg users. Worn or damaged seals can result in gas leakage or contamination. Every seal should be replaced regularly and especially worn out and damaged ones.
Storage
The storage of refill kegs is extremely important for the quality of the drink. Kegs should be stored in a cool, dry place out of direct sunlight. Sunlight can cause the drink's chemical composition to change, while heat will damage the keg material.
Transportation
When transporting refill kegs, they should be secured properly to avoid any kind of disturbance. It can affect the drink's quality if the keg is shaken or subjected to extreme temperatures.
The refill keg is a must-have for the homebrewing hobby to store carbonated craft beer. They keep longer than bottles and can be dispensed through a draft system for easy serving. Homebrewers can experiment with various beer styles without worrying about bottling or conditioning.
A refill keg is the perfect way to serve a large beverage in style at family parties. Fill it with homemade beer, lemonade, or iced tea, and use a keg tap to serve it to everyone. It will save the organizer hassle and mess, too, as the keg will be the ultimate solution for quenching everyone's thirst.
