Sediment vs. Lees — What's the Difference?
By Tayyaba Rehman & Maham Liaqat — Updated on April 27, 2024
Sediment generally refers to any particulate matter that settles at the bottom of a liquid, often seen in natural water bodies; lees specifically denotes sediments in wine or other alcoholic beverages after fermentation.

Key Differences
Sediment encompasses a broad range of particulate matter, including sand, silt, clay, and organic material, typically found at the bottom of bodies of water due to natural deposition processes. Whereas, lees specifically refers to the deposits that accumulate at the bottom of wine and other alcoholic beverages during and after fermentation. These deposits are primarily composed of dead yeast cells and other byproducts of the fermentation process.
Sediments can form through various natural mechanisms such as weathering of rocks and erosion, contributing to diverse ecosystems in aquatic environments. On the other hand, lees result from the intentional process of fermentation in winemaking, influencing the flavor, texture, and aroma of the final product.
In environmental science, the study of sediments is crucial for understanding sedimentation rates, pollution levels, and ecological impacts on water bodies. Conversely, in viticulture and brewing, lees are studied for their role in enriching flavors and contributing to the mouthfeel and complexity of wines and beers.
While sediment can be found in virtually any natural water setting, such as rivers, lakes, and oceans, lees are confined to the production environments of breweries, wineries, and distilleries. This distinction points to the differing roles and contexts in which these substances are considered and managed.
Sediment management often involves considerations of water clarity, ecosystem health, and pollution control. In contrast, the management of lees is focused on culinary applications, particularly in enhancing the sensory qualities of alcoholic beverages.

Sediment
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification.
Lees

Common Curiosities
What are lees in winemaking?
Lees are the deposits left at the bottom of wine after fermentation, consisting mostly of dead yeast cells.
What is sediment?
Sediment refers to any solid material that settles at the bottom of a liquid, often formed through natural processes like erosion.
How do sediments impact the environment?
Sediments can influence water clarity and quality, affecting aquatic life and ecosystem health.
What role do lees play in winemaking?
Lees contribute to the flavor, aroma, and texture of wine, often enhancing its complexity.
Can sediment be found in drinking water?
Yes, sediment can accumulate in water tanks or pipes and is often a concern in water treatment.
Is it safe to consume lees?
While lees are generally filtered out before bottling, they are non-toxic and can be consumed safely.
What are the ecological roles of sediment?
Sediment layers can create habitats and provide nutrients for various aquatic organisms.
What are common techniques for sediment analysis?
Techniques include sieving, chemical analysis, and microscopy to study particle size and composition.
How can lees affect the shelf life of a beverage?
Lees can protect against oxidation, potentially extending the shelf life of certain wines.
What methods are used to manage sediment in natural bodies of water?
Methods include dredging, sediment traps, and vegetation buffers to prevent excessive accumulation.
How are lees handled in breweries?
In breweries, lees are typically removed to avoid off-flavors, although some beer styles embrace lees for added character.
Are sediments always harmful to water systems?
Not necessarily; while excessive sediments can be harmful, normal levels are crucial for many aquatic ecosystems.
Why might a winemaker choose to age wine on lees?
Aging on lees can enhance the wine’s body and introduce secondary flavors and creaminess.
