Differences Between Glass and Plastic Fermenters

When selecting a fermenter, one of the major issues is whether to use glass or plastic. There are some pros and cons associated with each form of container. On the one hand, glass is a hardy material that provides excellent clarity when viewing the fermentation process through the tube. It’s also easy to clean and usually won’t impart any off-flavors to the beverage. Unfortunately, it can be difficult to store due to its size and fragility, so it may be more suitable for stationary setups where you have a dedicated idea of its location as a homebrewer.

On the other hand, plastic fermenters tend to be much lighter and easier to maneuver compared to glass ones. In addition, they are relatively inexpensive compared to their glass counterparts, and food grade plastic fermenters are popular among home brewers. 

Given both advantages and disadvantages accompanying each material type, the decision ultimately comes down to personal preference and the specific times they’ll be used. It’s important that brewer chooses the right size fermenter for their setup; otherwise, they may find themselves with too little or too much wort after fermentation. No matter what type of fermenter one chooses, make sure to place it in a cool, dark place, away from direct sunlight.

To learn more about this factor in detail, turn your attention now towards one thing: what size fermenter you will need for your desired brew. As you navigate through the world of home brewing, consider exploring various fermentation vessels including barrels, fermentation chambers, and other types of fermenter containers like aluminum crocks. Other alternative options include canning jars, lemon mix containers, and even cider and mead-specific containers inspired by the history of brewing.

What Size Fermenter Do I Need?

Once you have considered the differences between glass and plastic fermenters, including food grade plastic options, you will want to evaluate what fermenter size is appropriate for your needs. Size is a very important item to consider when it comes to fermenting because it has an effect on the overall brewing process. Some factors, like the capacity of the fermentation vessel and the intended production scale, are to be considered. Depending on the number of fermentations you plan to do, you may need a small or large vessel.

On the one hand, investing in a larger-capacity fermenter, such as fermentation buckets, rubber stopper equipped containers, or a fermentasaurus, may be more cost-effective in the long run and could save time—glasses need refilling more often than larger containers and can allow more room for expansion. This can be beneficial if you are scaling up production or have a higher demand for faster fermentation cycles, which might be the reason for opting for a larger fermenter. However, a disadvantage to larger fermenters is that they may require additional investment in equipment, such as dedicated kombucha equipment, spoon, cloth, lots of fermentation weights, and other products.

On the other hand, choosing a smaller-capacity fermenter might be a suitable solution at the beginning stages of the brewing hobby and may not require as much cost or space. Smaller fermenters are ideal for experimentation and testing, allowing brewers to get creative without having to commit to bigger batches. Trying your hand at home brewing with a couple of small-scale experiments also reduces the chance of infection in your brew and handles the impact of experimenting with lower-risk factors. 

The size of your fermenter, whether it’s a porcelain vessel or an HDPE gallon jug, ultimately comes down to several reasons, such as how many batches you plan on making, how much beer you expect to produce daily and weekly, as well as other considerations such as storage constraints and financial resources available. 

When choosing the appropriate fermenter size and material, you can further enhance your homebrewing experience by investing in high-quality kits like SS Brewtech or FastFerment and exploring helpful tips for successful brewing ventures. One such tip could be opening various release mechanisms in models of glass jugs or other equipment often used in brewery settings, like valves and fruit fermenters, for added variety and strength in flavor. 

Additionally, consider investing in a PET system to help regulate the temperature and keep unwanted bacteria out. You may also want to sample unique ingredients, such as a lemon liqueur in your brew, or even set up a dedicated home bar area to showcase and mix your creations. With a few simple tips and proper navigation, you can ensure a successful fermentation process every time.

As you browse through numerous online sale listings and explore various blog posts and articles in different categories, take note of the many options available to home brewers looking to expand their knowledge and make an informed decision that will elevate their homebrew to new heights. Remember to exercise patience in this process, as perfecting your brewing techniques may take time, whether it’s for your own version of vodka or rum.

  • A typical homebrew setup uses a 6.5-7 gallon plastic or glass carboy as the primary fermenter, along with a 6-gallon bucket as the secondary fermenter.
  • According to homebrew supply shops, most brewers prefer to use glass or plastic as their primary fermenter since it is more durable and easier to clean.
  • The size of the fermenter should correspond to the amount of beer being brewed; generally speaking, 1 gallon of fermentation space is needed for every 5 gallons of beer being brewed.

Volume vs. Capacity

Now that the reason for choosing a specific size of your fermenter has been discussed, let us move on to another topic within brewing – discussing the differences between volume vs. capacity as they pertain to fermentation equipment. No matter if you’re making something like kombucha, beer, cider, mead, or even region-specific drinks such as rum with lime, understanding capacity and volume is essential for choosing the right fermentation vessel for your kitchen. 

In the brewing process, your fermentation vessel typically needs to hold about 15-20% more liquid than your total recipe. Things like copper jugs, oak bottles, or alternative green options like fermentation weights and porcelain containers, such as amber glass jugs, may also need to be factored in, depending on your brewing setup and the reasons behind your chosen equipment. Brown drinks, popular in establishments around the world, may influence your choice of equipment too. 

Considering different brands and options, such as fermenters specifically designed for lacto-fermentation or those commonly used in restaurants, will ensure that you make an informed decision regarding your health and brewing needs when serving a diverse range of drink options.

Bottom line, while capacity is an important factor you must consider if you are going to be regularly brewing batches beyond five gallons, paying attention to the volume of your fermentation vessel is far more important. The majority of homebrewers will not need anything larger than a five-gallon fermenter with secure lids, regardless of whether they are using glass, plastic, or metal. Some fermenters may even come with helpful features like an airlock, spigot, or dedicated space for bottles or mason jars. 

Depending on the type of beer you are making and its ingredients, such as pieces of fruit or using more yeast, a higher amount may require a larger volume fermenter. Always opt for one that handles slightly more than your expected brew output when picking out a vessel. This could prevent off flavors, contamination from an overflow, or exposure to unwanted elements, such as airlocks or brine.

Additionally, consider investing in a fermenter with a durable valve to manage fermentation strength with ease, or a fabric strainer for separating solids from liquids. However, it’s always best practice to measure each ingredient, like the juice extracted from fruits or lime, in your recipes separately for accuracy. Having a hands-on approach and considering if you’ll need space for bottles, gallon batches, and possibly storing a jar, measuring your batch size beforehand can help determine the optimal size for your fermenter. 

This discussion serves the purpose of guiding you to make the right selection of brewing equipment. It also leaves openings for additional items like a brush for cleaning or oxygenation equipment. With the knowledge of what size fermenter is needed and which type would work best for your unique requirements, transitioning into measuring recipes becomes straightforward. You can even refer to MoreBeer or other brewing websites to find valuable resources, such as ports and links to buy necessary brewing tools like bucket fermenters, while browsing other cone-shaped fermenters.

Measuring Your Recipe

Once you understand the difference between volume and capacity, the next step is to measure your recipe. The size of your fermenter should reflect the volume of wort produced by your recipe, such as wines or other beverages.

As a general rule of thumb, you should have at least one gallon per pound of grains in your mash, along with five to ten gallons for boil off and yeast assimilable nitrogen. This way, you can ensure a successful home brewing experience without the worry of overloading your equipment, compromising the quality of your final product, or disappointing your customers with subpar drinks. 

To that end, brewers often use larger fermenters than what is actually needed to ease their brewing course. This allows them to add more ingredients, such as pieces of fruit, cinnamon, or ice, or distill wash for spirits without overflowing their equipment. Moreover, it opens up various choices for experimentation with different ways and forms to brew unique stuff like health-oriented foods or beverages, such as coffee-based cocktails.

At this point, you’ve considered volume vs. capacity and measured your recipe; now it’s time to pick a material for your fermenter and even come up with a fitting name that represents your home country. Metal fermenters offer many advantages to brewers, from heavy-duty construction to temperature control capabilities – but more on that later. 

Also, consider glass containers, which enable you to monitor the brewing process. Glass containers are particularly useful for fermenting milk kefir or supplies like cheese, as they can showcase the changes occurring during fermentation and are perfect for cocktail-making endeavors. It’s important to cover glass containers with a cloth or a lid secured by a rubber band to prevent fruit flies or other contaminants from spoiling your brew.

Metal Fermenters

Metal Fermenters

Metal fermenters are becoming an increasingly popular choice in the brewing environment today, thanks to the many advantages they offer. Unlike glass and plastic vessels which can be prone to breakage and scratching, metal fermenters are extremely durable and can last for years as long as they’re taken care of properly. Further, the lockable lid on many metal fermenters provides added security and sanitation – especially if you live in an area where animals, dust infiltration, or exposure to environmental factors is a concern. 

One downside to metal fermenters is their price, which can be quite expensive and might deter some customers compared to glass and plastic vessels, especially if you’re new to homebrewing. Additionally, metal fermenters tend to have less surface area compared to glass, making it harder to observe the fermentation process as it reaches its end. 

This article will help you understand the different options available and guide you in choosing the right fermenter for your needs. Finally, it is important to note that metal fermenters should only be made from stainless steel. Any other type of metal could potentially leach chemicals into your beer, causing off flavors and poor tasting brews. 

With that said, measuring how much beer or cocktail you plan to make will be instrumental in helping you choose the size and diameter of the fermenter, like a hopping bucket fermenter. That decision, plus a careful review of your materials, will help determine whether glass, plastic, or metal is best suited for your brewing needs. 

As you gain experience, you might even start brewing hundreds of varieties of beers and share them with friends. Now let’s explore another factor when choosing the right equipment—kegging versus bucket fermentation, taking into account the risk associated with different fermentation tools, such as the fermonster, stopper, fittings, and their effect on the final product, including gas levels and cases.

Kegging vs. Bucket Fermentation

Kegging vs. Bucket Fermentation

Now that we understand the advantages of metal fermenters, let’s look at two common fermentation methods: kegging and bucket fermentation.

Kegging is often preferred as it requires less involvement and leaves less room for error. All you have to do is rack your beer from the fermenter into a keg and let natural carbonation occur, thereby reducing the weight of carbon dioxide (CO2) handling and the need for gas fittings. Jars of yeast and hops can be easily added during this process using a pump, making it a cost-effective choice for both the brewer and customers in many cases. Therefore, it can be done in much less time than bottling or racking into glass containers or buckets for secondary fermentation. 

On the other hand, while bucket fermentation takes longer and involves more steps, it offers an increased level of refinement over kegging. It allows for greater control over the fermentation process, such as gas levels, and might be preferred by some homebrewers who use a fermonster with a tight stopper. 

For example, suppose you are hoping to achieve a particular flavor profile or level of clarity that is not attainable through kegging alone. In that case, bucket fermentation may be worth your time. Additionally, beginners can find different types of fermenters like conicals, ceramic containers, and even yogurt or water kefir vessels, which make the bucket fermentation process more accessible. 

Ultimately, the decision between kegging versus bucket fermentation comes down to the level of quality desired by the brewer and whether accommodating factors such as cost, time, or accessibility are of concern. With this said, however, metal fermenters are particularly well-suited for both processes as a method of fermentation due to their strong build quality and long life span. 

To maintain proper acidity, consider using a scoby with a glass jar or another suitable vessel. But also consider the shipping costs if ordering online, along with the case and accessories such as caps. Before making your choice, review a list of available fermenters to find the one that best suits your needs. 

Before discussing the pros and cons associated with different materials for fermenting containers, it is important to note that all three major ones (glass, plastic, or metal) can be beneficial depending on the brewing process chosen. Armed with the right information and the appropriate tools like stoppers and fittings, you’ll be able to make a sound decision that suits your needs.

Pros and Cons of Different Materials

When deciding between the three materials for a fermenter, there are many factors to consider. Glass is often perceived as the superior choice in terms of quality, but this is only part of the picture. It offers excellent visibility for monitoring the fermentation process but is also easy to break, resulting in potential scratches and increasing contamination risk. This makes it an unreliable long-term option for those who ferment regularly or don’t want to worry about replacing their vessel frequently and dealing with broken cases. Glass jars are ideal for culturing yogurt or housing a water kefir scoby, both of which require less vigorous fermentation. 

Plastic is usually the most affordable material and comes with considerable flexibility. It’s highly resistant to light and oxygen, so plastic buckets and carboys make great cold storage vessels, suiting a variety of brewing needs. Most plastics, including BPA-free options, are lightweight, which makes transport easy with the aid of a jug and funnel.

Metal is arguably the sturdiest choice and works especially well for high gravity beers that require plenty of stirring while fermenting. Steel and stainless steel containers are both highly durable and food grade, the latter generally being considered superior amongst brewers due to their superior ability to resist corrosion, alcohol, and tarnish. 

What matters most is finding a vessel with a good seal that suits your fermentation and budget needs without compromising on quality or safety standards.

Frequently Asked Questions and Answers

How can I tell which fermenter is right for my brewing needs?

Glass fermenters are the most common and are preferred by many craft brewers since they are easily sanitized and resistant to scratches, which can lead to contamination. They also provide excellent visibility so you can monitor the fermentation process, making them suitable for brewing endeavors that may include yogurt or water kefir cultures using scobys in glass jars. Plastic fermenters, including those made with mouth-friendly BPA-free materials, are a cheaper option than glass but not always ideal since they can interact with some types of beer ingredients and are more likely to scratch over time, leading to contamination. 

With a lot of options available, your choice ultimately depends on your needs and preferences. In their conical style, metal fermenters are the most durable option. They often have features such as temperature controls and the ability to settle trub at the bottom without issue, which may be beneficial. The conical shape and narrow neck also aid in separating the beer from the sediment, making it an excellent tool for beer making. 

So when choosing a fermenter for your brewing needs, take into account all of these factors, as well as the number of kegs it can accommodate, before deciding which one will work best for you.

What are the best uses for each type of fermenter?

Glass Fermenters: Glass is a generally inert material, making it ideal for avoiding unwanted interactions between the fermenting beer and the fermenter itself. This makes glass an excellent choice for brewers who are new to fermentation, as it’s impossible for them to introduce unwanted flavors from the fermenter into the finished beer. Additionally, glass is relatively easy to clean, sterilize and inspect and doesn’t require any additional treatment like plastic and metal does before use. 

Plastic Fermenters: BPA-free plastic fermenters are not ideal for aging or storing beer, but they are less expensive than most other types of fermenters, so they’re often used as starter tanks. In general, plastic will also impart fewer flavors into the beer than glass. It can be rigid enough to provide good temperature control without cracking due to pressure changes caused by fermentation gasses. 

Metal Fermenters: Metal tanks are great for storing large quantities of beer in commercial operations since they can handle more extreme pressure changes than either glass or plastic during fermentation. While metal is a durable option that brewers won’t need to replace often, it does have some drawbacks. For one, since stainless steel has been shown to impart metallic flavors into light beers such as lagers, it isn’t well-suited for these styles unless treated with a coating beforehand. Additionally, metal is much harder to clean and sterilize by hand compared to glass and plastic containers.

What specific advantages and disadvantages do glass, plastic and metal fermenters offer?

Glass fermenters offer a number of advantages over their plastic and metal counterparts. The most significant advantage is that glass does not leach toxins and will not interfere with the flavor of your finished product. Glass also allows for better monitoring of the fermentation process as it is a relatively clear material. 

However, glass fermenters do come with some drawbacks. For starters, they are generally expensive and can be quite fragile compared to their plastic and metal counterparts. 

Plastic fermenters offer a number of advantages over glass and metal fermenters. They are far more affordable than either type and are also lightweight, which makes them ideal for transport. In addition, the interior design is often customizable (i.e., designed with spigots). The biggest drawback to plastic fermenters is that certain compounds from the material can leach into the beer during fermentation, leaving an off-flavor or aroma in the finished product. 

Metal fermenters have some great benefits. They are lightweight and durable compared to glass or plastic fermenters and are still able to handle extreme temperatures without breaking down structurally like their glass counterparts. 

On the downside, metal can easily rust when exposed to humidity and water, which can taint flavors in the beer being fermented and make cleaning difficult due to its sharp edges and potential iron oxide buildup in crevices on its surface. Additionally, tastes/aromas imparted by the metal itself may be noticed in very light beer styles—particularly those fermented at warmer temperatures where metal ionization occurs at faster rates.
