Anti-Microbial Beverage Tubing vs. Standard Tubing in Draft Systems: Benefits and Cons

Pros and Cons of Anti-Microbial Beverage Tubing vs. Standard Tubing in Draft Systems

When it comes to maintaining the quality and safety of beverages in a draft system, one important consideration is the type of tubing used to transport the liquid from keg to tap. Recently, anti-microbial tubing has gained popularity due to its potential for enhancing hygiene and prolonging the lifespan of draft systems. But does it offer enough benefits to justify its use over standard tubing? Here’s a breakdown of the advantages and disadvantages of anti-microbial beverage tubing versus standard tubing to help you make an informed choice.


Anti-Microbial Tubing Pros & Cons

Benefits of Anti-Microbial Beverage Tubing

Improved Hygiene and Reduced Contamination

Anti-microbial tubing is designed to inhibit the growth of bacteria, mold, and other microorganisms that can form biofilms. Biofilm buildup is one of the main causes of off-flavors, contaminants, and clogs in draft systems. The anti-microbial properties of this tubing help prevent microbial growth, making it easier to maintain a clean and safe beverage line.

Extended Cleaning Intervals

Standard tubing requires frequent and rigorous cleaning to avoid biofilm accumulation, but anti-microbial tubing can reduce the frequency of cleanings. Although regular maintenance is still necessary, the anti-microbial properties provide an added layer of protection, which may lessen the cleaning workload over time.

Preservation of Beverage Quality and Taste

Unwanted microbial growth can introduce off-flavors, diminishing the beverage’s intended taste. By reducing microbial presence, anti-microbial tubing helps maintain the original flavor profile of drinks, preserving quality from keg to tap. This is particularly important for establishments or home users with sensitive palates or a focus on specialty brews and craft beverages.

Enhanced Durability and Longevity

Anti-microbial tubing is often made with more durable materials to withstand both the anti-microbial treatment and the daily demands of a draft system. This can result in longer-lasting tubing that may resist wear and tear better than standard tubing, potentially reducing the frequency of replacements and long-term maintenance costs.

Cons of Anti-Microbial Beverage Tubing

Higher Upfront Cost

Anti-microbial tubing tends to be more expensive than standard tubing, which can be a deterrent for some. Businesses or individuals with large systems may find the higher initial investment substantial, especially if they’re unsure of the long-term benefits.

Potential for Chemical Leaching

Some anti-microbial additives may raise concerns about chemical leaching, although most reputable manufacturers ensure that tubing is food-safe. However, for users who prioritize chemical-free materials, this could be a point of contention, as anti-microbial treatments rely on specific compounds to achieve their effect.

Limited Effectiveness Over Time

The anti-microbial properties in the tubing may diminish over time, especially with prolonged use and frequent cleaning. This can mean that after a certain point, anti-microbial tubing might perform similarly to standard tubing, potentially negating the initial benefits and requiring replacement.

Compatibility Issues with Certain Beverages

Some anti-microbial tubing can interact with certain beverages differently, possibly impacting flavor over time or being less effective with certain ingredients (such as those in high-acidity drinks). Testing compatibility with your specific beverages is advised before making a full switch.

Environmental Impact

Anti-microbial tubing may have a higher environmental impact compared to standard tubing due to its specialized materials and potential use of chemicals in the anti-microbial process. For environmentally-conscious users, this may be a significant consideration.


Standard Tubing Pros & Cons

Benefits of Standard Tubing

Lower Cost

Standard tubing is typically less expensive, making it a cost-effective choice for draft systems, especially for high-volume systems or those with numerous lines to maintain.

Simpler and Familiar Maintenance

Standard tubing is widely used and well understood, meaning cleaning and maintenance procedures are straightforward, with no special handling required for anti-microbial properties.

More Environmentally Friendly Options

Standard tubing is available in a range of materials, some of which are more environmentally friendly than the compounds used in anti-microbial tubing. Recyclable or biodegradable options can be more readily available in standard types, appealing to eco-conscious users.

No Risk of Chemical Leaching

Standard tubing, without anti-microbial additives, may be a better choice for those concerned about additives in their beverage lines. This helps ensure that only beverage-contact-safe materials are used without additional compounds.

Cons of Standard Tubing

Higher Maintenance Requirements

Without anti-microbial properties, standard tubing is more susceptible to biofilm buildup and requires more frequent cleaning. This is particularly true in warmer environments or high-traffic systems, where microbial growth can quickly impact beverage quality.

Potential for Flavor Contamination

Over time, standard tubing can harbor microorganisms that impact the taste of beverages, especially if the tubing isn’t cleaned thoroughly or often enough. This is especially problematic in systems that dispense a variety of beverages with different pH levels and ingredients.

Shorter Lifespan

Standard tubing may not be as durable as anti-microbial options, especially under heavy use, which can lead to more frequent replacements and additional costs in the long run.

Conclusion: Choosing the Right Tubing for Your Draft System

The choice between anti-microbial and standard tubing depends on your specific needs, budget, and priorities. If you value lower maintenance, enhanced hygiene, and durability and are willing to invest in a higher upfront cost, anti-microbial tubing may be a worthwhile upgrade. However, if you prioritize budget and a simpler system with predictable maintenance requirements, standard tubing might still be your best option.

Regular maintenance is essential regardless of tubing choice, as even anti-microbial tubing doesn’t eliminate the need for clean lines.
