Types of Draft Beer Towers

12 types of draft beer towers based on function, design, or configuration are listed below:

1. Standard Towers

Standard towers are the most common type of draft beer tower found in commercial bars and home setups, typically featuring a single column with one to three taps, which is sufficient to support small to medium-sized businesses. These towers are highly popular due to several advantages they offer, such as being easy to install, cost-effective, and compatible with most kegerators or countertop systems available on the market.

In essence, their most significant advantage is simplicity and affordability compared to other units. However, standard towers have certain disadvantages, such as lacking aesthetic flair or volume capacity compared to more advanced or customizable models, which makes them less ideal for high-traffic or high-end establishments such as hotel bars or beer-focused pubs.

2. T-Towers

T-Towers are draft beer towers that feature a horizontal arm at the top of a vertical column, offering more than four taps for service in a compact design. They’re more popular in mid-size bars aiming for both volume and aesthetics. The main advantage of t-towers is efficient utilization of space and increased pour capacity. Thanks to four or more taps, multiple bartenders can serve simultaneously, significantly reducing wait time for customers.

However, the cons of t-towers are that their upfront costs can be higher than standard model,s and the installation may require more professional help as it is more complex. Temperature consistency varies if the lines aren’t well insulated or glycol-cooled like standard models.

3. Double-Pedestal Towers

Double-pedestal towers are draft beer towers that have two support columns for extra stability and capacity. They are typically used in larger establishments and possess 6 to 12 taps or more, which is great for rush hour service or serving a broad range of different beers. The most significant advantages of double-pedestal towers are their performance and durability; however, these advantages give rise to two main disadvantages: the need for more space and a more complex installation process.

You need to restructure the pipes from your storage to your service area and do some reconstruction in the meantime. Space is a valuable commodity for a business, and every piece of bar equipment should be carefully measured and purchased in the required size and capacity to avoid wasting any space.

4. Underbar Mounted Towers

Underbar-mounted towers are draft beer towers installed below the bar to keep the surface area clutter-free while utilizing the space underneath the counter. They’re ideal for sleek, modern designs and or customer-facing setups where aesthetics matter.

The main benefits of these units are their visual appeal and space-saving features. However, it is worth noting that access for maintenance and line cleaning is more difficult in underbar units, as the majority of components are located under the bar, facing the wall. Underbar-mounted towers may be less intuitive for bartenders used to standard upright systems.

5. Specialty Towers

Specialty towers are draft beer tower systems that come in custom shapes, finishes (such as ceramic or copper), and branded designs for high-end establishments seeking to enhance their beer service with a distinctive, branded touch. They enhance the look of a bar and improve customer experience by blending in with the interior design or featuring unique properties to maintain the taste and temperature of the beer.

The benefits of owning a specialty tower include a unique design and brand differentiation, as well as the ability to add custom features tailored to your needs. However, specialty towers have cons too, such as they are typically more expensive, and because they are custom-made,  they may require non-standard fittings or lines, which makes maintenance and parts replacements way more complicated compared to a standard unit.

6. Countertop Draft Beer Towers

Countertop draft beer towers are self-contained, portable units designed to sit on countertops in smaller establishments with limited beer service needs. They’re easy to install and move, but typically support fewer taps and smaller kegs. Their simplicity and low cost are substantial advantages, but they don’t offer the volume or cooling capabilities of larger systems, which are must-haves in larger bars.

7. Multi-Keg Beer Tower Systems

Multi-keg beer tower systems are draft beer towers designed to serve multiple types of beer simultaneously by combining several kegs in a single structure and dispensing them through separate taps. They’re must-haves for beer bars or restaurants offering different types of beers.

The most obvious advantage of owning a multi-keg beer tower system is its versatility, as it allows bars to experiment with different menu offerings. However, this benefit comes at the cost of a significant downside: the need for a complex keg room setup with greater installation and cleaning demands. Considering that the downside is mostly a one-time issue, the investment is worthwhile for large establishments; it’s typically overkill for home use or small venues.

8. Battery-Powered Draft Beer Towers

Battery-powered draft beer towers use battery-operated pumps instead of CO2 or nitrogen systems to maintain pressure. The battery system makes them portable and practical for outdoor events or temporary installations for caterers. The independence from gas lines, in particular, is a huge pro, making installation, clean-up, and mobility easier.

On the other hand, the poor consistency and pressure control offered by the battery system tend to be inferior to traditional systems, which utilize CO2 or nitrogen. Battery life and pump reliability can be concerns in the long run, and the unit may require more frequent maintenance to ensure longevity.

9. Draft Beer Towers for Outdoor Bars

Draft beer towers for outdoor bars are similar to standard models but are specially designed for outside use, featuring extra durability, weather resistance, and added insulation or built-in refrigeration. There is a wide variety of outdoor units to choose from, suitable for use on patios, backyard bars, or more commercial settings, such as hotel gardens.

Thanks to weatherproofing and added durability, these units can handle environmental exposure. On the other hand, these units tend to be more expensive and require specialized maintenance to prevent corrosion or sun damage.

10. Self-Pour Draft Beer Towers

Self-pour draft beer towers are designed for self-service operations, featuring integrated POS technology that allows customers to serve themselves without needing a bartender. These systems increase customer engagement and reduce labor costs, which makes them ideal for modern, high-tech establishments, open buffet settings, or large pubs with crowded happy hours. The cons of self-pour draft beer towers include high initial costs, software integration, and the need for more frequent and stricter sanitation controls due to customer contact.

11. LED-Lit Draft Beer Towers

LED-lit draft beer towers are equipped with LED lighting to draw attention to the unit and enhance ambiance in customer-facing areas of the bar. They are often used to highlight premium beer products or in themed bars to show off the beer collection. Their visual impact is a clear pro, but they typically require additional wiring and may need repairs if the lighting system malfunctions. They offer style over practical utility, which may cause issues in high-capacity establishments.

12. DIY Tap Towers

DIY tap towers are custom-built by beer lovers at home or budget-conscious business owners using kits or upcycled materials. The biggest pros of these units are that they allow full customization and cost control to the buyer.

However, the quality varies widely depending on the builder’s skill. DIY towers may lack the durability, cooling efficiency, or pressure regulation of commercial-grade towers and may endanger your inventory if not built correctly. It is safer to opt for a commercial-grade unit to protect your inventory from spoilage in the long run.

Comparative Considerations for Draft Beer Towers

Choosing between CO₂ and nitrogen, selecting nitro or standard towers, or determining the ideal tap setup helps align your draft system with your bar’s drink selection and service flow.

Factors like gas type, beverage compatibility, and intended use can significantly impact performance and quality. Whether you’re deciding between CO₂ and nitrogen, nitro vs. standard towers, or selecting the optimal tap setup for your space, these comparisons help tailor your draft system to match your operational goals and beverage menu.

CO2 vs. Nitrogen for Draft Beer Towers

CO2 and nitrogen are the top two gases used to maintain carbonation and pressure in draft beer towers. CO2 is the standard gas for most beer types, and it is commonly used in standard units to create carbonation and consistent pours. Nitrogen is a more exclusive option, as it is preferred for nitro beers to give the beer a creamier texture and smaller bubbles, enhancing the drinking experience.

CO2 is cheaper and easier to manage, while nitrogen requires special tanks, faucets, and restrictor plates. Choosing the wrong gas can ruin the pour or flavor of a beer, so the choice must align with the style of the beverage. If you are not offering niche beers, a CO2 unit is your best bet for standard use.

Nitro Beer Towers vs. Standard Towers

Nitro beer towers utilize specialized faucets and nitrogen gas to deliver a smooth, creamy pour, creating stouts and some porters, as well as more nitro-based niche drinks. The primary benefit of using a nitro beer tower over a standard tower is the texture and visual appeal achieved through the use of nitrogen instead of CO2.

However, most beers are better off with CO2, and the use of nitrogen is limited. Nitro beer towers are more expensive than standard towers and are less versatile. If you are keen on serving nitro beers, though, a CO2 standard unit cannot create the desired results, and you need a nitro tower.

Single-Tap vs. Multi-Tap Towers for Home Use

Single-tap vs. multi-tap towers for home use raises the question of whether you need a compact, affordable unit for daily use or a dedicated space to entertain guests or enjoy different types of beer simultaneously. Single-tap beer towers can be easily fitted on counters, are affordable, and easier to manage. Their sole function is to maintain and serve high-quality beer.

Multi-tap towers offer more variety and are ideal for home enthusiasts who frequently entertain guests or enjoy a wide range of brews. However, they take up more space, cost more, and require more cleaning and gas management. The choice entirely depends on your drinking habits and the available space.
