Sanke vs Corny Keg: Ultimate Brewing Showdown Unleashed

When comparing Sanke vs Corny Keg, understanding their differences can help you choose the right keg for your brewing or serving needs. Sanke kegs are often used by commercial breweries, while Corny kegs are popular among homebrewers. Each option offers unique features, depending on your setup and preferences. Let’s explore further.

Sanke vs Corny Keg Overview

When it comes to Sanke and Corny Keg, the options are designed to meet different needs in brewing and beverage dispensing. Sanke kegs are typically found in bars, restaurants, and commercial settings. They offer durability and ease of use for large-scale operations. Their single connection system makes them great for high-volume environments. They’re widely recognized for their seamless integration with professional equipment.

Corny kegs, on the other hand, are a favorite among homebrewers and smaller setups. They offer flexibility with their multiple fittings, allowing for easier cleaning and maintenance. Many appreciate their manageable size and ease of use in personal brewing systems. The Corny keg provides a hands-on approach to serving beverages.

Sanke Keg Overview

Sanke keg (also known as Sankey keg) is a barrel used mostly by commercial brewers to store and dispense beer, cider, soda, and other carbonated beverages. The barrel was first used in the United States of America by Hamn’s in 1978, replacing the unsanitary traditional barrels like bungholes. 

So, how does this barrel work to ensure you dispense beer without any hassle? Well, Sanke has a single valve at the top that allows both gases (mostly CO2) and beer to pass through via a coupler.

Sanke also features a spear in the valve that runs to the bottom. When the gas is connected, it pushes beer to the bottom, and then it penetrates up through the spear for dispensing. Most of them also feature a pressure relief valve (PRV) to release excessive pressure. This ensures safe storage and dispensing.

There are different sizes of Sanke kegs that hold different volumes of beer and other beverages. Here are some common types:

  • 1/2 barrel keg(full size-keg): This type holds approximately 15.5 gallons (58.67 liters) of liquid. It is the standard size of keg and is mainly used by commercial brewers to transport beers in bars and restaurants.
  • 1/4 Barrel Keg: Also known as a “quarter keg” or “pony keg,” it holds approximately 7.75 gallons (29.33 litres) of liquid.
  • 1/6 Barrel Keg: This size is often referred to as a “sixth barrel” or “sixtel” and holds approximately 5.16 gallons (19.56 litres) of liquid. It’s commonly used by craft breweries and for specialty beers.

Sanke keg also comes in different types, depending on the coupler design and the region where the keg is used. Here are some of the types:

  • D-Type Coupler (American Sanke): This is the standard coupler used in the United States and many other countries. It has a large lever handle and is compatible with most American-style beers.
  • S-Type Coupler (European Sanke): Commonly used in Europe, this coupler has a smaller lever handle. It is used for beers from breweries that follow European standards.
  • A-Type Coupler: This is used most in German beers. Some of the beers stored and transported in this keg include Spaten, Pulaner, and Hacker-Poschorr.
  • U-Type Coupler: This is another common coupler in the UK. It is commonly used with Guinness and Harp Kegs.
Beer Keg sizes

Advantages 

  • They come in different sizes, making it easy to hold different beer volumes depending on the occasion. 
  • They come in different types, allowing commercial brewers and other people to choose one compatible with their couplers.
  • They help keep beer cold (when stored at an ideal temperature or in a kegerator) and fresh.
  • They help eliminate unnecessary costs of bottling and packaging. The beer is siphoned directly from the fermenter to keg and poured into a glass through the tap.
  • They have an airtight seal that helps prevent oxygen and other bacteria from entering the beer.
  • They are made of stainless steel, a material that can withstand a rigors of commercial uses and, hence, last longer.

Disadvantages

  • Sanke couplers and fittings vary depending on the brewery. Therefore, not all Sanke kegs are compatible with each other. This can make it challenging to switch between different beers or brands.
  • Their size and weight can make transportation and storage less efficient, especially in smaller spaces or for mobile setups.
  • Some may be lacking the in-built pressure release valve (PRV). This makes it challenging to release excessive pressure inside the keg.

Corny Keg Overview

A corny Keg (also called Cornelius or soda keg) is a pressurized stainless steel canister that stores and dispenses beer and other carbonated drinks. The keg was first made by Cornelius, Inc. and was mainly designed for soft drink industries. 

Cornelius keg has become popular among homebrewers and craft beer enthusiasts for its convenience and ease of use. It can hold up to a maximum pressure of 130 psi, making it one of the most versatile equipment in the brewing industry.

So, how does the barrel work, and is it easy to use? Okay, the corny keg has two ports that help dispense beer. One is for “gas in,” and the other one is for “liquid out.” These ports are labeled to ensure you connect them correctly. 

Both ports have tubes to aid in the movement of gas and liquid, in this case, beer. The gas port has a shorter tube that does not touch the liquid inside. Its main work is to supply gas (CO2 or nitrogen gas) into the keg, pressurizing it to push beer out through the outlet.

The liquid port, on the other hand, has a long tube that reaches the bottom of the keg. When the gas is forced into the keg through the INLET, it pushes beer from the bottom through the tubes until it reaches “out port.”

Like the sanke keg, a corny keg also comes in different sizes. For instance, it comes in sizes of 5-gallon (19-liter) and 2.5-gallon (9.5-litre). The 5-gallon is the standard size for homebrewing, while the 2.5-gallon is often used for experimental batches or when you have limited space.

Advantages

  • They are made of stainless steel, which resists corrosion and is durable
  • They are equipped with a pressure relief valve or lid that can be released to relieve excess pressure inside the keg.
  • A corny keg has a central opening, which is wide enough to allow you to clean the inner parts. This opening is also used to fill it with your favorite drink.
  • They are compatible with various fittings and connectors, making it easier to find replacement parts or customize your setup.
  • They come in different sizes, making them suitable for different batch sizes and storage constraints.
  • They are conducive to DIY modifications, such as adding additional taps, temperature control systems, or kegging accessories.

Disadvantages

  • They require regular maintenance to ensure they function well and are free from contaminants. This can be time-consuming, especially if you have other things to do.
  • Corny kegs come in various sizes but are generally smaller than commercial kegs. This limitation can be a disadvantage if you need to serve large quantities of beverages.
  • The rubber seals and O-rings in corny kegs can wear out over time, potentially leading to leaks or loss of carbonation if not properly maintained.
