Understanding keg taps and draft beer systems
How draft beer flows from keg to glass
Draft beer systems are designed to deliver fresh, cold beer straight from the keg to your glass. At the heart of this process is the keg tap, a device that connects the keg to the dispensing system. The tap allows beer to flow out while maintaining the right pressure inside the keg, ensuring each pour is smooth and flavorful.
- Keg taps come in various designs, each suited for different keg types and setups.
- Draft systems use CO2 or nitrogen to push beer through the lines, preserving carbonation and taste.
- Proper setup and maintenance are key for avoiding foamy or flat pours.
Understanding how these systems work helps you choose the right tap and materials for your needs. If you’re curious about the larger equipment involved in draft beer, check out this guide on beer tanks and their role in brewing.
Types of keg taps: sankey, ball lock, and more
Popular keg tap styles explained
When it comes to serving draft beer, the type of keg tap you choose can make a big difference in your pouring experience. There are several styles, each designed for specific keg types and setups. Here’s a look at the most common options:
- Sankey (D System): The industry standard in North America, Sankey taps are widely used by commercial breweries. They feature a single valve for both gas and beer, making them efficient and reliable for most domestic kegs.
- Ball Lock: Originally used for homebrewing, ball lock taps are popular with Cornelius (Corny) kegs. They have separate connections for gas and liquid, offering flexibility for home setups and smaller batches.
- Pin Lock: Similar to ball lock, pin lock taps are also used with Cornelius kegs but have a different locking mechanism. They are less common but still favored by some homebrewers for their ease of use.
- S-Type and A-Type: These European styles are used for certain imported beers. S-Type is common for many European lagers, while A-Type is often found with German and some UK brands.
Choosing the right keg tap depends on the type of keg you’re using and your serving needs. If you’re planning to set up a new draft system or upgrade your current one, you might find this guide to brewery installation helpful for understanding the broader setup process.
Once you’ve identified the right tap, you’ll want to consider the material and features, which we’ll cover next. This ensures your draft system delivers the best possible pour every time.
Choosing the right material: stainless steel vs. regular steel
Comparing stainless steel and regular steel for keg taps
When selecting a keg tap, the material plays a crucial role in both performance and longevity. The two most common materials are stainless steel and regular (often chrome-plated) steel. Each has its own advantages and considerations for homebrewers and professionals alike.
- Stainless steel: Known for its durability and resistance to corrosion, stainless steel is a popular choice for those who want a long-lasting tap. It is non-reactive, which means it won’t affect the taste of your beer, and it’s easy to clean. This makes it ideal for frequent use or for those who value quality pours every time.
- Regular steel: Often used for more budget-friendly options, regular steel taps are typically coated to prevent rust. However, over time, the coating can wear off, especially with heavy use or improper cleaning. This can lead to rust and off-flavors in your beer.
For anyone serious about their draft system, investing in stainless steel is usually worth the extra cost. Not only does it ensure a cleaner taste, but it also stands up to the rigors of regular use.

Keep in mind that the choice of material also ties into other factors like price and availability, which are important to consider as you continue setting up your ideal draft system.
What to look for in a keg tap: price, delivery, and sale options
Key factors when purchasing a keg tap
- Price range: Keg taps are available at a variety of price points. Entry-level models are affordable and suitable for occasional use, while premium taps offer durability and advanced features for frequent pouring. Consider your budget and how often you plan to use the tap.
- Delivery options: When buying online, check the delivery times and shipping costs. Some retailers offer free or expedited shipping, which can be helpful if you need your tap quickly for an event or gathering.
- Sales and promotions: Look out for discounts, bundle deals, or seasonal sales. Many suppliers offer deals on keg taps, especially when purchased with other draft beer equipment.
- Warranty and support: A good warranty can provide peace of mind. Check if the manufacturer or seller offers customer support in case you have questions or issues with your tap.
- Compatibility: Make sure the tap you choose matches the type of keg and draft system you have. This ensures a secure fit and optimal performance, as discussed in the earlier sections about tap types and materials.
Taking the time to compare these factors will help you find a keg tap that fits your needs and budget, making your draft beer experience smoother and more enjoyable.
Setting up your keg tap for the perfect pour
Preparing your keg and tap system
- Chill your keg for at least 24 hours before tapping. Cold beer reduces foam and ensures a smooth pour.
- Place your keg in an upright position. Make sure it is stable and not shaken, as agitation increases foam.
- Inspect your tap and lines for cleanliness. Any residue can affect flavor and cause excess foaming.
Attaching the tap correctly
- Align the tap with the keg valve. For Sankey taps, insert and twist to lock; for ball lock or pin lock, ensure a tight fit on both gas and liquid posts.
- Secure all connections. Leaks can lead to loss of carbonation and wasted beer.
- Open the CO₂ tank slowly to pressurize the system. Set the regulator to the recommended PSI for your beer style.
Pouring the perfect pint
- Hold your glass at a 45-degree angle under the faucet. Open the tap fully in one quick motion to avoid excess foam.
- Straighten the glass as it fills, aiming for a 1-inch head of foam for optimal aroma and presentation.
- If you notice too much foam, check the temperature, pressure, and cleanliness of your lines.
Troubleshooting common issues
- Flat beer? Check for CO₂ leaks or low pressure.
- Foamy pours? Ensure the keg is cold, lines are clean, and pressure is correct.
- Off flavors? Clean your tap and lines regularly to maintain beer quality.
