There’s something undeniably satisfying about pouring a cold pint of draft beer from your own kegerator. Whether you’re a homebrew hobbyist, a backyard party regular, or just someone who enjoys the crisp taste of draft beer without leaving the house, a kegerator delivers that bar-quality experience with surprising ease.
Over the last few years, kegerators have grown in popularity—not just as a novelty item, but as a serious addition to home kitchens, garages, and entertainment spaces. With dozens of styles, configurations, and features on the market, choosing the right kegerator can be more complicated than it looks. This guide is designed to help you understand what a kegerator is, how it works, and what you need to know before making your purchase.
What Is a Kegerator?
At its core, a kegerator is a specialized refrigerator designed to store and dispense beer from a keg. It keeps the beer at the ideal serving temperature and uses a pressurized CO2 system to pour from a tap—just like you’d find at a bar.
But modern kegerators go far beyond that basic function. Today’s models come with digital temperature control, dual-tap systems, stainless steel construction, and even outdoor ratings. Some are built into kitchen islands, while others roll on casters so you can serve beer wherever the party is.
Whether you’re storing a commercial keg, homebrewing your own batches, or serving cider, kombucha, or nitro cold brew, there’s a kegerator that fits your needs.
Types of Kegerators
Kegerators come in several different designs, each suited for different use cases. Here’s a breakdown to help you find the right category.
Freestanding Kegerators
These are the most common type for home users. They look like compact refrigerators with a tap tower on top and often come with wheels for mobility. Freestanding models are easy to install and ideal for garages, basements, game rooms, and patios (if properly rated).
Built-In Kegerators
Also known as undercounter kegerators, these are designed to integrate with cabinetry and ventilation systems. They’re more expensive but provide a sleek, permanent look that works well in custom home bars or high-end outdoor kitchens.
Outdoor Kegerators
Built with weather-resistant materials and extra insulation, outdoor kegerators are made to withstand temperature swings and exposure to the elements. They’re perfect for patios, outdoor kitchens, and covered decks. Make sure your model is specifically rated for outdoor use.
Mini or Desktop Kegerators
Smaller units that hold mini kegs (typically 1.5 to 5 liters), these models are perfect for casual beer drinkers or for limited-space environments. They don’t offer the same power or performance, but they’re affordable and convenient.
Commercial Kegerators
Designed for bars, breweries, and restaurants, these units can hold multiple full-size kegs and include advanced cooling systems. They’re not always practical for home use, but if you’re serious about beer service, some high-capacity models may be worth considering.
What Can You Serve in a Kegerator?
Although beer is the traditional choice, today’s kegerators are used for a variety of beverages. Here’s what’s possible with the right setup:
- Domestic and craft beer
- Homebrew beer
- Cold brew coffee
- Kombucha
- Sparkling water
- Cider
- Wine (with wine-rated components)
- Nitro beverages
Make sure the internal components—especially the coupler, tap, and CO2 setup—are compatible with your drink of choice. Some liquids require nitrogen gas instead of CO2, and acidic beverages like wine or kombucha need stainless steel lines and fittings.
Key Features to Consider
A kegerator isn’t just a beer cooler. The best models offer reliable performance, user-friendly controls, and the flexibility to fit your space and preferences. Here’s what to look for when shopping:
Capacity
Most freestanding kegerators fit a single full-size half-barrel keg (15.5 gallons), but some models can hold two smaller sixth-barrel or Cornelius kegs, allowing you to pour two different beverages from one unit. Pay attention to the internal dimensions and keg compatibility.
Number of Taps
Single-tap kegerators are standard, but dual- and triple-tap models let you serve more than one beverage at once. If variety is important to you—or if you entertain often—consider a multi-tap system.
Temperature Range
The ideal serving temperature for most beers ranges from 34°F to 40°F. High-end models offer digital temperature control with adjustable settings for different styles of beer. Wine, kombucha, and nitro coffee may require different temperature zones.
CO2 Tank and Regulator
The CO2 tank pressurizes the keg and allows the beer to flow through the tap. Most home kegerators come with a 5-pound CO2 tank, which can serve several full kegs before needing a refill. The regulator ensures consistent pressure, which affects both carbonation and pour quality.
Drip Tray and Guard Rail
These minor features can make a big difference in cleanup and presentation. A removable drip tray keeps spills contained, while a guard rail helps prevent glasses from sliding off the top.
Interior Components
Look for stainless steel or chrome-plated brass components to ensure longevity and avoid off-flavors. Plastic or low-grade metal parts can affect the taste of beer over time and are harder to sanitize.
Mobility
If you plan to move your kegerator between spaces, a model with locking casters is ideal. These wheels make it easier to clean, rearrange, or roll the unit outdoors for special events.
Conversion Kits
Some buyers choose to convert a mini-fridge into a kegerator using a DIY conversion kit. While this can be more affordable, it requires some technical skills and often voids the appliance’s warranty.
Pros and Cons of Owning a Kegerator
Owning a kegerator can be a game-changer, but it’s not for everyone. Here’s a quick look at the upsides and potential drawbacks:
Pros
- Cost savings over time if you buy beer by the keg
- Always have fresh, cold draft beer on tap
- Perfect for entertaining and social gatherings
- Reduces single-use cans and bottles
- Can serve multiple types of drinks
Cons
- Upfront cost for the unit and accessories
- Requires occasional cleaning and maintenance
- Needs space and proper ventilation
- You must have access to keg refills or distributors
Who Should Buy a Kegerator?
Home Entertainers
If you frequently host parties or events, a kegerator adds convenience and a wow factor. Dual-tap models let guests choose between beverages, and the consistent pour eliminates the mess of cans and bottles.
Beer Enthusiasts and Homebrewers
For craft beer lovers, a kegerator is a must-have. It preserves flavor better than bottles or growlers and allows you to enjoy your favorite brews exactly as the brewer intended. Homebrewers can keg their own creations and enjoy pro-level dispensing at home.
Garage and Backyard Enthusiasts
Whether you’re building a man cave or upgrading your outdoor kitchen, a weather-rated kegerator turns any space into a social hub. With portable models available, you don’t need to be locked into one location.
Budget-Conscious Drinkers
Buying kegs can save significant money over time, especially for those who prefer high-end craft beer. With proper use, a kegerator pays for itself in reduced packaging and bulk buying power.
Final Thoughts
Kegerators may have started as a niche appliance for die-hard beer fans, but today they’ve gone mainstream. Thanks to better design, energy efficiency, and flexible configurations, owning a kegerator is more accessible than ever.
Whether you’re sipping an IPA after mowing the lawn, serving cold brew to brunch guests, or experimenting with nitro kombucha, the right kegerator can elevate your everyday experience.
