Sanke Beer Kegs

Sanke kegs, often spelled Sankey, are the standard beer keg in the US. Breweries have filled them for years, and today they also carry coffee, kombucha, tea and other craft beverages. A single valve on top lets gas in and beer out, and a Sanke D coupler connects the keg to your draft system.

Our stainless steel Sanke D kegs run from 10L up to the 1/2 barrel (15.5 gallons). Buy individual Sanke kegs, or order by the pallet for a brewery, roastery or winery. Standard Sanke kegs need special equipment to clean and fill. If you don't have it, our hybrid and tri-clamp Sanke kegs have removable lids. We also carry replacement spears, parts and tools.

What Is a Sanke Keg?

A Sanke keg (also written Sankey) is a closed stainless steel keg with one valve on top. A tube called the spear runs from that valve to the bottom of the keg. When you attach a coupler, CO2 flows in at the top and pushes the beer up through the spear and out to the faucet. Most US brewery kegs use the D-style valve, so a Sanke D coupler fits the majority of kegs you'll tap.

The Anatomy of a Sanke Keg

At its core, a Sanke keg is a specialized type of beer keg, renowned for its simplicity and efficiency. What sets it apart from other keg varieties is the presence of a single valve located at the top of the keg. This valve serves as the gateway through which both beer and gas traverse, facilitating the seamless flow of your favorite brew from keg to glass.

To better understand the mechanics at play, let's break down the components of a typical Sanke keg:

  1. Sanke Keg Valve:
    Positioned atop the keg, the valve is the nerve center of the operation. It orchestrates the passage of both beer and gas, ensuring a harmonious flow within the keg.
  2. Sanke Keg Spear:
    The spear is a critical component housed within the valve. Extending from the top to the bottom of the keg, it plays a pivotal role in transporting beer from the depths of the keg to the awaiting glass.
  3. Gas Flow:
    Gas, typically carbon dioxide (CO2), enters the keg and flows to the upper portion. This gas exerts pressure on the beer, propelling it upwards through the spear and ultimately out for dispensing.
  4. Beer Flow:
    On the journey from keg to glass, the beer follows a path guided by the spear. It moves from the bottom of the keg, where it resides, up through the spear, and eventually emerges for consumption.

Sanke Keg Sizes: Choices Galore

Just as beer aficionados relish the diversity of beer styles, Sanke kegs come in a variety of shapes and sizes to cater to different needs. Here are some of the most common Sanke keg sizes you might encounter:

    Popular in Europe and gaining recognition worldwide, the 13.2-gallon keg, or Euro Sanke keg, caters to a diverse range of beer styles and preferences.

Sanke Keg Couplers: The Key to the Treasure Chest

To access the liquid treasure concealed within a Sanke keg, you'll need a keg coupler, sometimes referred to as keg taps. Think of the coupler as a trusty key that unlocks the potential of the keg. It's the essential tool that bridges the gap between the keg's valve and the dispensing system, ensuring a smooth pour.

While several types of keg couplers are available, the D-style coupler reigns supreme in the United States as the most commonly used. This coupler is tailored to fit the majority of Sanke kegs found in the U.S., making it a staple tool for bars, restaurants, and breweries.
