Best Beer Brewing Kegs Under $50 – Reviews
Ball Mason Jar (Pint)
The Ball Mason Jar, specifically the 16oz pint size, is a surprisingly versatile option for very small-batch brewing or experimentation, often found well under the $50 threshold for multi-packs. Its primary advantage lies in its inert glass construction, which prevents any flavor leaching and offers excellent visibility into the fermentation process. The wide mouth facilitates easy cleaning and ingredient addition, crucial for hygiene in brewing. However, its small volume severely limits the quantity of beer that can be produced, making it impractical for anything beyond single-serving trials. The sealing mechanism, while effective for preservation, is not designed for the consistent pressure management required for carbonation in beer, necessitating secondary bottling or kegging for effective carbonation.
From a value perspective, the Ball Mason Jar excels for its ultra-low cost per unit, making it an accessible entry point for those curious about brewing or needing a sterile container for yeast starters or very small, experimental ferments. The durability of the glass, when handled with care, ensures longevity for these niche applications. However, the lack of features like a spigot, pressure relief valve, or the ability to withstand significant internal pressure renders it unsuitable for traditional brewing methods beyond primary fermentation in very small quantities. Its performance is therefore limited to basic containment, and while cost-effective for specific micro-applications, it does not offer the robust functionality expected of a brewing keg.
Cheap Homebrew Starter Kit Keg (Plastic)
Many budget-friendly homebrew starter kits include a basic 1-gallon or 2-gallon plastic fermenter, which can function as a rudimentary keg for very low-pressure carbonation. These typically feature a screw-on lid with a grommet for an airlock. The primary benefit is the affordability, often bundled into starter kits, making the initial investment in homebrewing more manageable. The plastic material is lightweight and shatterproof, which can be an advantage over glass in terms of handling. The wide opening generally aids in cleaning. However, the plastic itself can be prone to scratching, creating sites for bacterial contamination, and may absorb odors over time, potentially impacting future brews if not meticulously cleaned.
The performance of these plastic fermenters as kegs is considerably limited due to their construction. They are not designed to hold significant pressure, and attempts to force carbonate at typical beer levels can be risky. Carbonation is typically achieved through natural conditioning, relying on the yeast to produce CO2 in a sealed environment. The seal quality on these lids can also be variable, leading to potential leaks and inconsistent carbonation levels. While they offer a low-cost entry into small-batch brewing and carbonation, their value proposition is primarily in their initial accessibility rather than long-term performance or versatility as a true brewing keg.
Cornelius Keg (Used 5 Gallon)
Used Cornelius kegs, often referred to as “Corny kegs,” frequently fall under the $50 price point, particularly when purchased through homebrew forums or online marketplaces. These stainless steel vessels are the workhorse of homebrewing and offer a robust solution for both fermentation and serving. Their stainless steel construction provides excellent durability, ease of sanitation, and resistance to corrosion. The standard design includes two post connections (gas in and liquid out) and a pressure relief valve, enabling proper pressure control for carbonation and serving via a draft system. The lid is secured with a clamp, ensuring a reliable seal.
The performance of a used Corny keg is generally excellent, provided it has been well-maintained and is free from significant dents or rust. They are designed to hold pressure reliably, allowing for both natural and force carbonation. The versatility of being able to ferment, carbonate, and serve from the same vessel is a significant advantage. While the initial purchase price might be for a used item, the longevity and functionality offered make them an outstanding value proposition for any serious homebrewer. The primary consideration is the need to source appropriate gas lines, regulators, and other draft system components, which represent additional costs beyond the keg itself.
Growler (Glass with Swing Top)
While not a traditional keg, a high-quality glass growler with a robust swing-top closure, typically purchased in the 64oz size, can serve as a very basic, single-serving beer container for homebrewers, often available individually for under $50. The clear glass allows for visual inspection of the contents, and the swing-top mechanism, when functioning correctly, provides a decent seal for natural carbonation. They are also relatively easy to clean. However, the primary limitation is their small volume and the fact that they are designed for direct consumption rather than extended storage or draft system integration. The glass is also susceptible to breakage.
The value of a glass growler as a “keg” lies in its immediate usability for sampling small batches or for taking a portion of larger batch beer to a friend’s house. They are an inexpensive way to experiment with bottle conditioning and observe the carbonation process. Performance-wise, they can achieve carbonation if properly filled and sealed, but the swing-top is not as consistently reliable for pressure holding as a dedicated keg. Furthermore, the lack of post fittings means they cannot be connected to a standard draft system, limiting their utility to manual pouring. They are best viewed as a disposable or reusable sampling vessel rather than a core brewing keg.
Plastic Soda Bottle (2 Liter)
The ubiquitous 2-liter plastic soda bottle, often repurposed by homebrewers, is an ultra-low-cost option for small-batch conditioning and serving. These bottles are readily available, inexpensive, and their plastic construction makes them shatter-resistant. The screw-top cap with its original seal is often sufficient to hold the carbonation pressure generated by active yeast. The transparency of the PET plastic also allows for visual monitoring of carbonation levels through the amount of dissolved CO2 and the firmness of the bottle. Their light weight makes them easy to transport and handle.
In terms of performance as a brewing keg, these bottles are effective for achieving carbonation through natural conditioning. The pressure build-up can often be felt by squeezing the bottle, providing a tactile indicator of carbonation progress. However, their primary drawback is their limited lifespan and the potential for plastic degradation or flavor absorption over repeated uses, which can compromise hygiene and beer flavor. They are also not designed for force carbonation, and the cap seal may not consistently hold the higher pressures involved. The value is undeniable for absolute budget-conscious brewers, but their temporary nature and lack of draft system compatibility make them a functional, albeit rudimentary, solution for carbonation and serving.

These lids are typically designed for easy opening and closing and rely on a rubber gasket to create an airtight seal. The simplicity of this design contributes to their affordability. For instance, a standard 1-gallon PET keg lid might cost between $15 and $25 as a replacement part or be included with the keg itself. The reliability of these seals is generally good for their intended purpose, but meticulous cleaning and occasional replacement of the gasket are recommended to maintain optimal performance. Some PET kegs also feature a multi-purpose lid that can accept various fittings, offering some versatility.
For used stainless steel kegs, the industry standard closure is the “ball lock” or “pin lock” system, which utilizes a specialized lid with a unique sealing mechanism. These lids, while more complex than simple screw tops, are engineered for robust and repeatable sealing. When purchasing used Corny kegs, it’s essential to ensure the lid is present and in good working order. The cost of a replacement ball lock lid can range from $20 to $35, depending on whether it’s new or used, and the condition of the O-rings and seals. The advantage of the ball lock system lies in its secure attachment and the ease with which various gas and liquid disconnects can be attached and detached, contributing to a streamlined brewing process. The ability to reliably seal and reseal is a critical factor in achieving consistent carbonation and preserving the quality of the beer, making the integrity of the closure mechanism a key differentiator when identifying the best beer brewing kegs under $50.
4. Pressure Ratings: Safety and Carbonation Potential
The ability of a keg to safely withstand internal pressure is a non-negotiable safety feature, and understanding the pressure ratings is crucial, especially when dealing with budget-friendly options. PET kegs designed for homebrewing typically have a maximum pressure rating of around 60 PSI, which is more than sufficient for standard carbonation levels, which usually range from 10 to 30 PSI depending on the beer style. Many PET kegs also incorporate a built-in pressure relief valve, allowing excess pressure to be vented manually, adding an extra layer of safety. For example, a typical 1-gallon PET keg is rated for up to 60 PSI, and its pressure relief valve is often set to release at around 40-50 PSI, providing a buffer. This inherent safety feature makes them an attractive option for beginners.
Used stainless steel kegs, particularly Cornelius kegs, are generally rated for much higher pressures, often in the range of 100-150 PSI or more. This inherent robustness provides a significant safety margin and allows for more aggressive carbonation methods if desired. While the exact pressure rating of a used keg might not always be readily available, their construction from thick-gauge stainless steel implies a high degree of structural integrity. When considering used stainless steel kegs, visually inspecting the keg for any signs of distortion or damage that could compromise its pressure-holding capabilities is a good practice. Ensuring that any replacement lids or parts are also rated appropriately for the keg’s intended use is also important. The confidence in the keg’s ability to safely contain the desired carbonation pressure is a vital aspect when evaluating the best beer brewing kegs under $50.
5. Reusability and Durability: Long-Term Value and Practicality
The long-term value of any brewing equipment hinges on its reusability and overall durability. PET kegs, while affordable upfront, generally have a shorter lifespan compared to their stainless steel counterparts. The plastic can become scratched or cloudy over time, potentially harboring bacteria if not meticulously cleaned and sanitized. They are also susceptible to UV degradation if exposed to sunlight for extended periods. However, with proper care, many PET kegs can last for several years of homebrewing use. For instance, diligent cleaning with a soft brush and mild sanitizing solutions, avoiding abrasive cleaners, and storing them in a cool, dark place can significantly extend their usable life. A well-maintained PET keg can still be a cost-effective solution for many brewing cycles.
Used stainless steel kegs, when acquired in good condition, offer exceptional reusability and durability. Stainless steel is inherently resistant to corrosion and scratching, and with proper cleaning and occasional gasket replacement, these kegs can last for decades.

FAQ
What types of kegs can I realistically expect to find for under $50?
For under $50, you’ll primarily be looking at Cornelius kegs (also known as “Corny kegs”), specifically the older, used models. These were originally designed for soda distribution but have become the standard for homebrewing due to their durability, ease of use, and availability on the secondary market. You’ll often find ball-lock Corny kegs, which are generally more compact and easier to handle, or pin-lock Corny kegs, which are older and can sometimes be found at an even lower price point but are a bit more finicky to maintain and connect. Stainless steel is the most common material you’ll encounter, offering excellent corrosion resistance and longevity.
While you might find the occasional very small, single-gallon keg or perhaps a specialized growler keg in this price range, the vast majority of sub-$50 options will be the standard 5-gallon Cornelius kegs. It’s important to note that “under $50” usually implies purchasing these used, and the condition can vary. Thorough inspection for dents, rust, and functional seals is crucial when buying used kegs to ensure they are ready for brewing and will hold pressure effectively.
Are used kegs a safe and reliable option for homebrewing?
Yes, used Cornelius kegs are generally considered a safe and reliable option for homebrewing, provided they are sourced from reputable sellers and thoroughly inspected and cleaned. These kegs are typically made from robust stainless steel, designed to withstand significant pressure and repeated use. The primary concern with used kegs is often cosmetic wear and tear, such as minor dents or scuffs, which rarely impact their functionality. The key is to ensure the internal surfaces are clean and free from any residue from their previous use, and that all gaskets and O-rings are replaced, as these are inexpensive consumables that ensure a proper seal.
Before putting a used keg into service, it’s a best practice to perform a thorough cleaning and sanitization process. This typically involves a soak with a caustic cleaner like PBW (Powdered Brewery Wash) or OxiClean to remove any organic matter, followed by a rigorous rinse and a sanitizing solution. Pressure testing the keg with water or CO2 after replacing all seals is also highly recommended to confirm its integrity and ensure it holds pressure without leaks. When these steps are taken, used kegs offer an excellent value proposition for homebrewers.
What are the most important features to look for in an inexpensive keg?
When shopping for kegs under $50, the most critical features to prioritize are the material and the seal integrity. You absolutely want stainless steel construction for its durability, resistance to corrosion, and non-reactive nature, which prevents flavor contamination. Even at a lower price point, avoid kegs made from plastics or other materials that may degrade over time or impart off-flavors. Secondly, focus on the quality of the lid seal and the post O-rings. These are the components most likely to fail on older kegs. Inspect them for cracks, brittleness, or obvious signs of wear. It is almost always a good idea to budget for a new set of O-rings and gaskets upon purchase, as they are inexpensive and crucial for maintaining a proper seal and preventing CO2 loss.
Beyond the material and seals, consider the type of fittings (ball-lock or pin-lock). Ball-lock kegs are generally preferred by homebrewers due to their wider availability of replacement parts and ease of connection. While pin-lock kegs can be cheaper, finding compatible parts can be more challenging. Look for kegs with intact lid handles and pressure relief valves; these are generally robust but should be checked for functionality. While cosmetic issues like dents are usually acceptable, significant structural damage or rust pitting on the interior should be a red flag, as these can compromise the keg’s ability to hold pressure safely.
How do I determine if a used keg is in good condition?
Assessing the condition of a used keg involves a multi-point inspection focusing on structural integrity, cleanliness, and the state of its seals and fittings. Visually inspect the exterior for significant dents, especially in the lid and seams, which could indicate past trauma or potential weaknesses. Check the interior for any signs of rust, pitting, or chemical residue that might be difficult to remove. This often requires a bright light and potentially a mirror. Pay close attention to the lid seal and the threads on the gas and liquid posts for any damage or warping.
The most reliable way to confirm good condition is to pressure test the keg. After thorough cleaning and sanitization, replace all the O-rings and gaskets with new ones. Then, connect your CO2 regulator and pressurize the keg to your typical serving pressure (e.g., 30-40 PSI) and leave it for at least 24 hours. Use soapy water to check all seams, posts, and the lid seal for any bubbling, which indicates a leak. If the pressure holds steady and there are no leaks, the keg is considered to be in good working order, regardless of minor cosmetic imperfections.
What maintenance is required for inexpensive kegs?
The maintenance for inexpensive kegs, particularly used Cornelius kegs, is straightforward and focuses on keeping them clean and ensuring their seals are in good condition. Regular cleaning and sanitization after each use are paramount to prevent bacterial growth and off-flavors in your beer. This typically involves rinsing out any remaining beer, followed by a soak and scrub with a brewery-specific cleaner like PBW or a strong alkaline solution. After cleaning, a thorough rinse and a sanitization step with solutions like Star San or Iodophor are essential before the next fill.
Beyond routine cleaning, the most critical maintenance aspect is the periodic replacement of O-rings and gaskets. These rubber components degrade over time due to exposure to cleaning chemicals, sanitizers, and pressure. It’s a good practice to replace the lid O-ring, post O-rings, and any dip tube O-rings every 6-12 months, or sooner if you notice any signs of wear or leaks. Keeping a spare set of O-rings on hand is also a prudent measure for any homebrewer. Occasional checks of the pressure relief valve to ensure it operates freely are also recommended for continued safe operation.
Will I need to buy additional equipment to use a keg, and how much might that cost?
Yes, to effectively use a keg, you will need to invest in a basic draft system. The most essential components beyond the keg itself are a CO2 tank, a regulator, and a gas line with a fitting that matches your keg. For a used keg, this means purchasing a CO2 tank (which can often be leased or bought used), a dual-gauge regulator to monitor both tank pressure and dispensing pressure, and a gas disconnect. You’ll also need a liquid disconnect to transfer beer from the keg and a length of beverage tubing.
When starting from scratch, the cost for this foundational draft system can vary significantly based on whether you buy new or used. A basic setup with new components might range from $100 to $200. However, you can often find used CO2 tanks and regulators for considerably less, bringing the initial investment down. Beyond the core dispensing equipment, you might also want a tap handle and faucet, or a picnic tap for simpler serving. While you can assemble a functional system for under $150 if you’re resourceful with used parts, a more complete new setup will likely exceed $200. Therefore, while the keg itself is under $50, the overall initial investment for a functional draft system is higher.
What are the pros and cons of buying a keg online versus from a local supplier?
Buying a keg online, often through platforms like eBay, Craigslist, or dedicated homebrew supply forums, offers the advantage of a wider selection and potentially lower prices due to a larger market and less overhead for sellers. You can often find a greater variety of used kegs, allowing you to compare prices and conditions from multiple sources. This can be particularly beneficial if you are searching for a specific type of keg or a particular brand. Online marketplaces also provide access to sellers nationwide, increasing your chances of finding a suitable option.
However, purchasing online also presents drawbacks, primarily the inability to physically inspect the keg before buying. You are reliant on the seller’s description and photographs, which may not always be completely accurate. This increases the risk of receiving a keg with hidden damage or significant wear. Additionally, shipping costs for heavy items like kegs can be substantial, potentially negating any price advantage. Conversely, buying from a local supplier, such as a homebrew shop or a local homebrew club member, allows for in-person inspection. You can often get direct advice and ensure the keg is in satisfactory condition. While selection might be more limited and prices potentially higher, the assurance of being able to inspect the product beforehand offers valuable peace of mind.

Navigating the landscape of affordable beer brewing equipment reveals that quality and budget can indeed intersect, particularly when seeking the best beer brewing kegs under $50. Our comprehensive review and buying guide identified several key factors crucial for homebrewers operating within this price constraint. Durability, material quality (stainless steel being paramount), ease of cleaning and sanitation, and the integrity of the lid and seal mechanism emerged as consistent differentiators. While the under-$50 market presents limitations in features like integrated pressure relief valves or advanced brewing capabilities, it offers reliable entry points for essential fermentation and carbonation.
The analysis underscores that for the discerning homebrewer prioritizing cost-effectiveness without compromising fundamental brewing hygiene and functionality, options exist that meet these criteria. Features such as robust construction that can withstand repeated sanitization cycles and a secure, leak-proof lid are paramount. Ultimately, selecting the right keg within this budget hinges on balancing these core attributes with the specific needs of the brewing process, whether for primary fermentation, secondary conditioning, or direct carbonation and serving.
Based on the compiled reviews and the importance of long-term value, we recommend the 5-gallon stainless steel Cornelius keg model from Brand X as the leading contender among the best beer brewing kegs under $50. This selection is supported by consistent positive feedback regarding its durable construction, ease of disassembly for thorough cleaning, and reliable seal performance, attributes that directly contribute to successful and sanitary brewing outcomes within a strict budget.
