Stainless steel wine fermentation tanks give you flexibility, control, and high quality, making them a smart choice for many winemakers.
Oak Wine Fermentation Vessels
Flavor Impact
When you use oak as a wine fermentation container, you create unique flavor profiles that stand out. Oak wood tanks, including barrique and foudre, add special flavors and aromas to wine. The material of the vessel matters a lot. Oak species, where the wood comes from, and how it is toasted all change the impact on wine flavor. You can taste vanilla, coconut, clove, nutmeg, cinnamon, toast, smoke, and spice in wines fermented in oak barrels. French oak gives subtle flavors and less oxygen, which helps you make elegant wines. American oak adds stronger flavors and more oxygen, making bold wines. The size and shape of the vessel, like a barrique or a foudre, also affect how much skin contact and oxygen the wine gets. This changes the expression and quality of the final product. Oak fermentation helps with malolactic fermentation, giving wine a creamy mouthfeel and balancing freshness and acidity.
Tip: The longer wine stays in oak, the more flavor complexity and aroma it gains. You can control this by choosing the right type of oak and how long you let the wine ferment.
Pros
- Oak wood tanks allow gentle oxygen exposure, which helps soften tannins and improve quality.
- You get unique flavor profiles, such as vanilla, spice, and toast, that make your wine stand out.
- Oak vessels support malolactic fermentation, which adds creaminess and smoothness.

If you want to highlight the impact on wine flavor and improve quality, oak is a classic choice for both traditional and modern winemaking.
Concrete Fermentation Vessels
Influence on Wine Flavor
Concrete fermentation tanks wine offer a unique way to shape the flavor and quality of your wine. When you use this material as your wine fermentation container, you combine the best features of oak and stainless steel. Concrete tanks do not add extra flavors like oak, but they allow gentle oxygen exposure through their porous walls. This micro-oxygenation softens tannins and helps balance the wine’s mouthfeel. For example, the Lalomba winery found that concrete tanks preserved fruit character and freshness while creating a juicier texture. Oxygen levels in concrete are about half those in oak, which influences malolactic fermentation and the final flavor balance. The composition of the concrete, such as the type of sand or stone, can even add a subtle mineral note, giving your wine a sense of place.
| Vessel Type | Material | Flavor Influence | Advantages | Disadvantages |
|---|---|---|---|---|
| Oak Barrels | Oak wood | Imparts vanilla, spice, tannins | Micro-oxygenation, tradition | Costly, requires upkeep |
| Stainless Steel | Stainless steel | Clean, pure, fruit-forward | Precise temperature control, inert | Limited oxygen exchange |
| Concrete Tanks | Concrete | Adds minerality, texture | Thermal stability, gentle oxygenation | Heavy, porous |
Benefits
You gain several advantages when you choose concrete tanks for fermentation. Concrete’s thick walls, often up to 5 inches, absorb and slowly release heat. This thermal stability keeps fermentation temperatures steady, which protects wine quality and supports healthy yeast activity. Concrete tanks wine allow for longer, cooler fermentations that enhance color, flavor, and tannin extraction. The shape of these tanks, such as egg or cone designs, helps natural circulation and keeps the lees moving, which boosts complexity and texture. Concrete’s gentle oxygenation supports balanced fermentation and improves the overall quality of your wine.
Tip: Concrete tanks come in many sizes, from small amphorae to large vessels holding up to 38,000 liters. You can match the tank size to your production needs.
Drawbacks
You should know about some challenges with concrete fermentation tanks wine. Scientific studies highlight these drawbacks:

Concrete is a smart choice when you value quality, flavor balance, and a sense of place in your wine.
Clay and Amphorae Fermentation Vessels
Flavor Profile
When you choose clay or amphorae vessels for wine fermentation, you unlock unique flavor profiles that stand apart from other methods. Clay is a porous material. It allows gentle oxygen exchange during fermentation. This process softens the wine and adds texture and complexity. Unlike wood, clay does not add its own flavors. Instead, it lets the grape’s true character shine. Modern winemakers often use amphorae to create wines with a distinct expression. You may notice more minerality, floral notes, and a round mouthfeel. For example, wines like the 2019 Vitalba Secco Albana show ripe stone fruit, ginger, and toasted hazelnut after 90 days in amphora. The 2018 Luccianus Amphore from Bordeaux displays black fruits and dense tannins, showing how this vessel shapes flavor.
Note: Clay amphorae allow a delicate oxygen exchange that influences chemical reactions during aging, softening tannins and enhancing complexity. This results in flavors and aromas you cannot achieve with stainless steel or wood alone.
Strengths
- Clay vessels give you a neutral base, so the grape’s natural flavor stands out.
- The slow oxygen exchange helps soften tannins and build complexity.
- Amphorae support a stable fermentation temperature, which protects wine quality.
- You can create wines with unique flavor profiles that highlight terroir and grape variety.
Limitations
Scientific research shows some limits when you use clay and amphorae for wine fermentation. The oxygen flow depends on how the vessel was made, so results can vary. You may find that commercial yeast strains do not always work well in these vessels. Indigenous yeast often adapts better to the clay environment. The porous material can also affect the wine’s polyphenolic and aromatic profile in ways that are not fully understood. Traditional methods, like those in Portugal, use pine pitch coatings and long contact with grape skins. These methods can change the wine’s shelf life and flavor. There is still a lack of scientific data on how these vessels affect fermentation and aging, so you may need to experiment to get the best results.
Suitable Wines
You should use clay and amphorae vessels when you want to make wines that express their origin and grape variety. These vessels work well for both white and red wines. For example, Pinot Noir, Albana, and Aglianico all show unique flavor profiles when fermented in amphorae. If you want to highlight minerality, floral notes, or a round texture, clay is a strong choice. You can also use these vessels to create natural or low-intervention wines, where the material supports a pure and honest expression of the grape.
Plastic and Glass Fermentation Containers
Flavor Considerations
When you use plastic or glass containers for wine fermentation, you can expect subtle differences in flavor. Scientific studies show that most people find only minor flavor changes between plastic and glass vessels. Some tasters notice slight differences, but these are not always linked directly to the container material. Factors like plastic aging or surface scratches may play a role. In other foods, such as Sichuan pickles, plastic jars can change the flavor profile more than glass. Plastic may lead to higher acid levels and different microbes, which can affect the final flavor of your wine. Glass, on the other hand, does not react with the wine and keeps the flavors pure.
Advantages
Plastic and glass containers offer several benefits for wine fermentation:
- Plastic buckets are lightweight and easy to move. You can clean them quickly and use them for short-term fermentation.
- Glass carboys keep oxygen out, which helps preserve the wine’s flavor and quality.
