Reinforced Beer Lines: For Higher Pressure Systems

Reinforced beer lines are robust and capable of enduring working pressures between up to 100 PSI. They owe their strength and ability to withstand high pressure to the materials used in their construction. These materials provide extra reinforcement, making reinforced beer lines ideal for high-pressure systems, similar to the durability of an air line.

Nevertheless, to avert typical problems such as foamy beer or beer not flowing, it’s vital to confirm that the pressure setting on the beer lines matches the required level to maintain keg carbonation.

Barrier Tubing: Advanced Flavor Protection For Remote Beer Systems

Beer Trunkline

Barrier tubing offers several advantages, including:

  • Minimizing bacterial growth
  • Preventing carbonation loss
  • Preventing flavor migration
  • Preserving the aroma and taste of the beverage

This tubing consists of vinyl and features a multi-layer construction, incorporating an ultra-smooth inner layer that serves as a barrier against flavor permeation. This design effectively minimizes flavor permeation into the tubing and migration to other beer lines, thereby upholding the intended taste profile of the beer.

Particularly in remote beer dispensing systems, like air shaft systems, barrier tubing plays a significant role in preserving the beer’s original flavor and freshness during dispensation from a distance.

Selecting the Proper Tubing Size for Your Draft System

The selection of the correct tubing size is key to dispensing beer appropriately. The size of the beer line determines the flow rate, the pressure needed to propel the beer through the line, and ultimately, the quality of your beer.

A 3/16 inch beer line is typically recommended for homebrew systems, facilitating the retention of CO2 in solution and preventing foam formation, thereby ensuring optimal draft beer dispensing for commercial beer systems. 3/8" I.D. is typically used as jumper lines in the walk-in cooler.

As per industry standards, the optimal lengths for beer lines typically depend on the setup of the draft system. Most home brew systems have jumper hose lengths around 4-5'. While Commercial systems can be 8-10'. Again, it depends on how the system is set up in the cooler walk-in.

The Role of Tubing Diameter in Beer Dispensing

The diameter of the tubing plays a significant role in determining the flow rate of beer. Smaller diameter tubing increases resistance and decreases the flow rate, whereas larger diameter tubing decreases resistance and increases the flow rate. A 3/16″ vinyl beverage tubing has a restriction value of 3 lbs per foot. As you can see below different-sized tubing have different restriction values which is important when it comes to balancing your beer system.

The tubing diameter also impacts the foam production during beer pouring, significantly influencing the taste and presentation of the beer.

Matching Tubing to System Requirements

Just as one size does not fit all, using beer tubing that does not meet the system requirements can lead to issues such as:

  • bad dispensing system
  • elevated pressure
  • reduced pouring speed
  • CO2 loss from the solution
  • subpar foam quality

Hence, the beer tubing size should align with the system’s requirements, demanding a delicate equilibrium between resistance and beer delivery. Following this practice ensures optimal performance and prevents issues like foaming or slow pours.
