Craft Beer

A complete craft beer draft system typically includes a Sankey keg, CO₂ cylinder, regulator, coupler, beverage lines, and a faucet or kegerator dispensing system.

Commercial draft systems rely on controlled CO₂ pressure to push beer from a sealed keg through beverage lines to a faucet. The system must maintain consistent pressure to preserve carbonation, prevent foaming, and ensure stable pour quality.

Most breweries, taprooms, and beverage operators build their systems around commercial Sankey kegs, paired with CO₂ cylinders, regulators, and couplers designed for professional beverage dispensing. Kegerator kits simplify installation by bundling these components into a ready-to-install system.

A Sankey keg is a stainless steel commercial beer keg that uses a standardized coupler system to dispense beer under CO₂ pressure.

Most North American breweries distribute beer in Sankey D-system kegs, which allow bars, restaurants, and distributors to use a universal coupler connection. This design simplifies logistics across breweries and dispensing locations.

Commercial Sankey kegs are built from durable stainless steel and designed for repeated cleaning, refilling, and transport. Their standardized spear and valve configuration makes them compatible with professional draft systems used throughout the craft beer industry.

The most common CO₂ cylinder sizes for craft beer systems are 5 lb, 10 lb, and 20 lb cylinders depending on dispensing volume.

Smaller cylinders are often used in homebrew or portable draft systems, while breweries, taprooms, and commercial bars typically use larger cylinders to support multiple taps and higher throughput.

Proper cylinder sizing helps maintain consistent pressure for carbonation and beer flow. Commercial operators often select larger cylinders to reduce refill frequency and ensure uninterrupted service during peak operating hours.

A kegerator kit typically includes a CO₂ cylinder, regulator, Sankey coupler, beverage lines, gas lines, faucets, and mounting hardware.

These kits are designed to simplify installation by providing all core components needed to convert a refrigerator or dedicated draft cabinet into a beer dispensing system.

For breweries, taprooms, and hospitality venues, kegerator kits reduce setup time and ensure compatibility between regulators, couplers, and draft lines. Many systems can also be expanded to support multiple taps or integrated into larger draft installations.

A beer keg conversion kit allows a draft system to adapt between different keg connection types such as Sankey, ball-lock, or pin-lock systems.

Conversion kits are commonly used by homebrewers, small breweries, and beverage labs that operate multiple keg styles. They allow existing dispensing equipment to connect with different keg formats without replacing the entire draft system.

This flexibility is useful for testing batches, serving pilot brews, or integrating commercial kegs into homebrew or specialty beverage systems.

Growlers are reusable containers designed for transporting fresh draft beer from a brewery or taproom to another location.

Many breweries offer growler fills to customers who want to take draft beer home while maintaining carbonation and freshness. Growlers are typically made from glass, stainless steel, or insulated materials.

For breweries and taprooms, growlers expand off-premise sales while preserving the draft experience. Proper sealing and pressure control help protect the beer from oxygen exposure and carbonation loss.

Common draft system components include couplers, disconnects, posts, poppets, O-rings, beverage tubing, and gas fittings.

Over time, seals and moving parts in a draft system experience wear from pressure cycling, cleaning chemicals, and repeated keg changes. Routine maintenance helps maintain consistent beer flow and prevents leaks or contamination.

Professional beverage operators often keep replacement components on hand so technicians can quickly service draft systems and minimize downtime.

CO₂ pressure controls both the carbonation level in the keg and the flow rate of beer through the draft system.

If pressure is too low, beer may pour slowly or lose carbonation. If pressure is too high, the beer may foam excessively or over-carbonate during storage.

Proper regulator adjustment keeps the draft system balanced. This ensures consistent pours, stable carbonation, and predictable dispensing performance across different beer styles.

Yes, many craft beer systems can be customized with branded kegs, cylinders, growlers, and dispensing hardware.

Customization is often used by breweries and beverage brands to reinforce product identity and maintain asset tracking across distribution networks. Branded equipment also improves visibility in taprooms, events, and retail environments.

Custom options may include laser engraving, screen printing, labeling, and color finishes depending on the equipment type and order volume.

Breweries typically select draft equipment based on serving volume, number of taps, keg type compatibility, and available CO₂ capacity.

Small taprooms may operate with single or dual-tap kegerator systems, while larger venues require multi-tap draft systems with higher-capacity CO₂ cylinders and regulators.

Selecting compatible kegs, gas cylinders, and dispensing components ensures reliable beer service, consistent carbonation control, and easier maintenance across the entire draft system.
