Choosing the right wine fermentation tank depends on several factors. When you start making wine from grapes, one of the first important decisions is what to use as a fermentation vessel. Common choices include plastic barrels and plastic boxes, glass or plastic carboys, stainless steel tanks and kegs, and traditional oak barrels. Different fermentation vessels will affect the style and taste of the wine.

Plastic fermentation tanks are a cheap and lightweight option, just make sure it is BPA-free, food-grade plastic. The top of a plastic fermentation tank is open, making it easy to reach and break the pomace cap, so plastic fermentation tanks are ideal for red wine fermentation. Some fermentation tanks come with lids and fermentation locks and can be used for both red and white wine fermentation. However, plastic scratches easily, so you must be careful when cleaning the fermentation tank. You should also consider bacterial spoilage. Excessive exposure to oxygen can introduce spoilage microorganisms into the fermenting grape juice. If you are looking for a versatile fermentation tank but can’t afford a more expensive solution, consider plastic buckets and plastic boxes.
Glass Bottles
Although most wineries use glass for storage and transportation, they also make great primary fermentation containers. Glass is a great material because it is inert and allows winemakers to have more control over the fermentation process. It is also relatively easy to clean because of its smooth surface. You can insert fermentation locks or rubber stoppers into glass bottles to prevent oxidation. They are also smaller in size, which means you can easily put them in the refrigerator to control the temperature. The downside is that they break when hit, let light through, and are limited in size.
Carboys are great containers for fermenting white wines, but with their narrow necks, they are not suitable for fermenting red wines. Carboys These are smaller glass containers that are often used for small-scale or personal winemaking. Carboys come in a variety of shapes but typically have a rounded bottom and a narrow neck, which helps reduce oxygen exposure. They are often used for secondary fermentation or short-term storage of wine.
Both glass carboys and narrow-necked carboys have a wide range of applications in the winemaking process, and the specific choice depends on the scale of production and personal preference.

Stainless steel fermentation tanks are the most popular type of container used in the winemaking process. They first appeared in the 1950s and took the wine world by storm. Today it is difficult to find a winery that does not use stainless steel fermentation tanks in the winemaking process.
Stainless steel wine fermentation tanks are mainly divided into two categories: closed tanks and open tanks.
- Open Fermentation Tanks: Designed specifically for red wine fermentation, open-top fermentation tanks provide unrestricted access to the grape caps while facilitating the immersion of the grape caps in them. Their spacious, sloping bottom ensures seamless and effortless removal of skins and seeds after fermentation.
- Closed fermentation tanks: usually have sealed lids or rubber seals, which can effectively control oxygen contact during fermentation and help maintain the fruity and fresh taste of wine. They are usually equipped with temperature control devices to accurately adjust the fermentation temperature, suitable for producing white wines that need to maintain stable flavor or red wines that are easy to oxidize.
Oak barrels
Oak barrels have a significant impact on the flavor and texture of wine. They can give wines complex aromas, tastes, and structures. If winemakers choose to use oak containers (which is very common in red wine production), they can allow oxygen to flow into the wine more slowly. Therefore, wines brewed from these containers have softer tannins. Depending on the degree of toasting of the oak barrels, the final flavor of the wine may be affected. Oak barrels vary in size, ranging from a minimum of 11 gallons to a maximum of 250 gallons. Each size of oak barrel has different uses, depending on the needs of the winemaker.
Ceramic pots
Ceramic pots are one of the oldest containers for winemaking. Compared with stainless steel or other materials, ceramic pots are generally more breathable and can allow wine to undergo moderate micro-oxygenation during fermentation. This helps the wine breathe during fermentation and aging and develops complex flavors. These clay fermenters were not widely adopted because they were very labor-intensive. Winemakers estimate that they could bottle 10 times more wine using modern stainless steel equipment. You also have to be careful when sterilizing. The pores in the clay are home to many microorganisms, but you can’t rinse the container with hot water. The clay might crack.
Why choose a conical fermentation vessel?
효모 수확량 향상
One of the significant advantages of conical fermentation vessels is the ease of yeast collection. Using a conical fermenter allows the winemaker to collect yeast from the bottom of the vessel without disturbing the sediment. This allows the yeast to be reused, saving time and money. By carefully collecting and reusing yeast, brewers can maintain brewing consistency and achieve desired flavors.
Enhance flavor and aroma.
Conical fermenters separate yeast and sediment, resulting in a cleaner, more refined final product. By minimizing contact with yeast and sediment during fermentation, conical fermenters help preserve the flavor and aroma of your beer or wine, resulting in a more enjoyable drinking experience. Imagine tasting a beer with a well-balanced flavor and pleasant aroma that will never be forgotten. This is the magic of the conical fermenter.
손쉬운 청소 및 유지 관리
Conical fermentation vessels are designed for easy cleaning and maintenance. The tapered shape easily removes sediment and yeast, simplifying the cleaning process. Additionally, many conical fermenters are made of stainless steel, making them very durable and easy to sterilize. This means winemakers and winemakers can spend less time scrubbing and more time focusing on their craft. With the right equipment, maintaining a sanitary environment for fermentation is a breeze.
How to choose the right wine fermentation container?
When choosing a wine fermentation vessel, it’s best to first understand the needs of the specific type and style of wine you want to produce, and then combine your budget and production capabilities to make the most appropriate decision.

- Wine type: Different types of wine may require different fermentation vessels. For example, white wine usually needs to maintain a fruity aroma and clear taste, so stainless steel or other materials that do not affect the flavor are often chosen. Red wines may be served in wooden barrels or clay pots to add complexity and taste.
- Material considerations: Conical fermenters are usually made of stainless steel or food-grade plastic. Stainless steel fermenters are known for their durability, making them a long-term investment. They are also easier to clean, which is a significant advantage when it comes to maintaining hygiene during fermentation. Additionally, stainless steel fermenters offer better temperature control, allowing you to control fermentation conditions more precisely.
- Size Capacity: The right size depends on your brewing or brewing needs. Consider the batch sizes you typically use and choose a fermenter that can accommodate your required capacity. There must be enough space for the fermentation process to take place without spillage or damage to the brew or the quality of the wine. Also, consider the space available in the brewing area. You want to make sure that the fermenter is installed comfortably and is easily accessible during the fermentation process.
- Fermentation Control: Consider how much control you need over the fermentation process. Stainless steel tanks are often equipped with temperature control systems that enable precise control of fermentation temperatures. Temperature control of barrels and clay pots may depend on environmental conditions, which may affect the fermentation process and final wine style.
