Oak segments are larger-format oak alternatives designed to provide extended contact time and gradual extraction in wine. They offer a slower release of oak compounds than chips or powder, allowing for deeper integration of structure and aroma over longer aging periods. Because of their size and extraction profile, oak segments are often used when winemakers want sustained oak influence without relying entirely on traditional barrel aging.
Understanding what oak segments are and how they behave helps ensure they are used intentionally within a winemaking program. When used thoughtfully, they can support structure, enhance mouthfeel, and contribute subtle aromatic complexity throughout extended maturation.
This guide explains how oak segments work, how they differ from other formats, and how to use them effectively in winemaking.
What are Oak Segments?
Oak segments are larger pieces of toasted wood that are added directly to wine during aging. They are typically bigger than cubes and smaller than full staves, providing a balance between surface area and extraction time. This makes them well suited for longer contact periods and gradual integration.
Segments are commonly used in tanks or larger vessels where extended contact time is desired. Because they release compounds more slowly than smaller formats, they can help build structure and complexity over time without introducing oak character too quickly.
For a broader overview of how segments fit into the full range of alternatives, see the main guide on oak alternatives for winemaking, which compares all oak formats and their roles.

How Oak Segments Influence Wine
When oak segments are added to wine, they gradually release compounds that interact with tannins and aromatic elements. Because of their size, extraction occurs more slowly than with chips or powder. This slower interaction allows the oak influence to integrate more deeply and evenly over time.
This makes segments useful when, longer aging periods are planned, gradual integration is desired, and a more subtle oak profile is needed.
Types of Oak Segments
Oak segments can vary based on wood type, toast level, and processing style. Each of these factors influences how they interact with wine.
Wood Types
French oak segments are often associated with subtle spice and refined structure. American oak segments may contribute more pronounced vanilla and sweetness. Maple and cherry segments can provide lighter, more delicate influences. Choosing the appropriate wood type depends on the wine style and the level of oak influence desired.

Toast Levels
Toast level plays an important role in the aromatic and structural compounds released during contact. Lighter toasts emphasize structure and subtle wood influence, while medium and heavier toasts introduce more aromatic complexity. Selecting the appropriate toast level helps ensure the oak complements the wine’s style.

Segment Size
Oak segments can vary in size and thickness, which affects extraction speed. Larger segments tend to extract more slowly and provide extended contact time, while slightly smaller segments may release compounds at a more moderate rate. Most winemakers select segment size based on how long they plan to age the wine and how gradual they want the oak influence to be.
At OCI, our segments are approximately 2" L x 3" W x 0.375" H in size but can vary.

When to Use Oak Segments
Oak segments are typically introduced during aging when a longer contact period is desired. Because they extract gradually, they are well suited for wines that will mature over several months.
Our experts recommend using oak segments in red wine during malolactic fermentation and after clarification in white wine.
Because segments are often left in contact longer than chips or powder, regular tasting helps determine when the desired level of integration has been reached.
Oak Segment Dosage Considerations
The amount of oak segments used depends on batch size, wine style, and desired intensity. Because extraction occurs gradually, dosage levels may differ from smaller formats.
For oak segments, our experts recommend using 20-30 grams per gallon (6-8 grams per liter).

Contact Time and Extraction
Contact time for oak segments is typically longer than for chips or powder. Because extraction is gradual, they may remain in contact for extended periods to achieve the desired level of integration.
Our experts recommend leaving the segments in contact for 5-6 months to impart appreciable oak flavor, but regular tasting throughout the aging process helps determine when the oak influence has reached the desired level.

Oak Segments vs Other Oak Formats
Segments may be preferred when a slower extraction is desired and gradual integration is needed.
Cubes may be preferred when a moderate extraction is desired with medium contact time.
Staves may be preferred when a very slow extraction is desired and long aging is planned.

Common Mistakes When Using Oak Segments
Even the best winemakers make mistakes and certain mistakes can lead to imbalance with your wine. Some common mistakes include using too many segments at once, leaving them in contact too long, not monitoring extraction, and choosing the wrong toast level for your wine.
Monitoring the wine and making gradual adjustments helps prevent these issues and ensures the oak integrates properly.
Final Thoughts
Oak segments provide a controlled, gradual way to introduce oak character into wine over extended aging periods. Their slower extraction allows for deeper integration of structure and aroma, making them useful for wines that benefit from sustained maturation.
When used thoughtfully and monitored carefully, they can help refine balance and complexity while maintaining flexibility in production.

Oak Segments FAQ
What do oak segments do in wine?
They provide gradual extraction of oak compounds, helping build structure and complexity over time.
How long should oak segments stay in wine?
Contact time varies depending on dosage and desired intensity. Because extraction is slow, they are often left in contact for extended periods.
Are oak segments better than cubes?
They serve different purposes. Segments provide slower extraction and longer contact time, while cubes provide moderate extraction.
Can oak segments replace oak barrels?
They can provide similar structural influence but are often used alongside other formats rather than as a full replacement. For a more detailed comparison, we recommend reading Oak Barrels vs. Oak Alternatives: Which is Better?
