What Is a Stainless Broth Chinois? (Mesh Specs)
A stainless broth chinois is a cone-shaped strainer used to separate stock or broth from solids. Its woven mesh sets how much passes through: a 40-mesh screen with 0.25 mm wire has a nominal opening near 0.385 mm, while a finer 60-mesh screen with 0.15 mm wire opens near 0.273 mm. Check both figures before buying.
When dinner depends on a pot of stock, the last step should not be a guessing game. A chinois can catch bones, vegetables, and fine particles, but product labels often say only “fine mesh.” That phrase does not tell you the opening size, how quickly broth will drain, or how clear the result may be.
Below, I explain the mesh numbers, how to select a stainless model, and how to strain without forcing liquid through a screen that is too fine. The examples are practical setups, not reports about specific tested products. Always check the dimensions and care instructions for the chinois you own or plan to buy.
Stainless Chinois Materials and Mesh Selection
A stainless chinois is a cone-shaped strainer with a handle and a mesh or perforated body. For broth, woven mesh gives a stated opening size that can help you judge what it may catch. The alloy, wire thickness, cone size, and support also affect how well it works.
What does mesh count mean?
Mesh count is the number of openings along one linear inch of screen. It is not a complete measure of fineness: wire thickness also takes up space, so two screens with the same count can have different openings.
To estimate a woven screen’s nominal opening, convert one inch to 25.4 mm, divide by the mesh count, then subtract the wire diameter:
Opening ≈ (25.4 mm ÷ mesh count) − wire diameter
This is an estimate for a regular weave. The manufacturer’s stated aperture, or opening size, is more useful when available. Real products may vary due to weave style, production tolerances, and how dimensions are measured.
| Mesh count | Wire diameter | Nominal opening | Likely use |
|---|---|---|---|
| 40 mesh | 0.25 mm | 0.385 mm | General stock straining; a practical balance of flow and particle capture |
| 60 mesh | 0.15 mm | 0.273 mm | Finer filtering; slower flow and greater risk of clogging |
These examples do not guarantee a particular level of broth clarity. A chinois catches particles larger than its openings, but dissolved material, very small particles, and particles that change shape can still pass through. A finer screen often drains more slowly and can clog sooner.
Which stainless steel should I look for?
For a food-contact strainer, look for a clearly identified stainless grade and a manufacturer’s food-contact information. Type 304, often sold as 18/8, is a common choice. Type 316 is another option, with greater resistance to chloride corrosion. Verify the alloy and any compliance claim with the maker rather than relying on “stainless” alone.
A chinois is a strainer, not a pan. It does not need an induction rating, a preheat time, or an oil-smoke-point limit. Hot stock may be close to boiling, about 100°C at sea level, but there is no single maximum-use temperature for every chinois. Follow the maker’s limits, especially for the handle, welds, and other joints.
What else should I check before buying?
Mesh is only one part of the choice. Check the stated opening, cone capacity, handle attachment, and whether the cone can sit securely over your pot or bowl. A wide cone may accept a larger batch, but it still needs stable support.
- Woven mesh has crossing wires and defined openings. Ask for both mesh count and aperture.
- Perforated metal has punched holes, not woven openings. Compare the listed hole diameter instead of treating a hole count as mesh count.
- Cone size affects how much liquid it can hold at once. Follow the maker’s capacity guidance, if provided.
- Construction should have sound welds, a firm handle, and no loose or bent mesh.
Preparing and Straining Broth
Prepare the chinois so it rests securely over a suitable vessel and can take the hot liquid without tipping. Rinse the mesh before use. Then pour or ladle stock in controlled batches, letting gravity do the filtering when clarity matters.
Set up the strainer safely
- Inspect it. Check the mesh for holes or dents, the welds for cracks, and the handle for looseness. Do not use a damaged strainer for hot liquid.
- Choose a stable support. Set the cone over a bowl or pot that holds it upright. The tip should not touch the bottom, where it could block drainage.
- Rinse the mesh. A rinse removes dust or residue. You may wet it with hot water to reduce temperature loss and help it sit against the vessel.
- Do not heat it empty. The chinois is intended to strain liquid, not to be heated as cookware.
Strain in controlled batches
Ladle or pour hot stock into the cone in manageable amounts. Keep one hand on the handle if needed, and avoid filling it so high that liquid spills over the rim. For clearer broth, allow it to drain by gravity rather than pressing the solids.
Pressing can extract more liquid, but it may also push fine particles through the mesh and make the broth cloudier. The effect depends on the solids and the screen. If you want a fuller extraction, press gently and expect that the result may be less clear.
What if the mesh clogs?
Starch, proteins, and fine food particles can block small openings. If drainage slows sharply, stop pouring and let the liquid settle or drain. Forcing broth through with a spoon or heavy pressure can distort or rupture fine mesh and may cloud the liquid.
Try one of these steps instead:
- Use a coarser strainer first to remove large solids.
- Reduce the amount in the cone and strain in smaller batches.
- Use the chinois for the first pass, then use a finer secondary filter if the recipe needs it.
- Allow a clogged screen to drain before cleaning it; do not push hard against the mesh.
Cleaning, Inspection, and Storage
Clean a chinois soon after use so food residue does not dry in the weave. Let it cool safely, remove solids, then wash with detergent and a soft brush. Rinse and dry it promptly. Gentle cleaning helps protect the mesh and its joints.
Clean without distorting the screen
First, let the strainer cool enough to handle safely. Remove large scraps, then wash both sides with dish detergent and a soft brush. Brush with the weave rather than scraping across it, and rinse until no food remains trapped in the openings.
Do not shock hot mesh with cold water; a sudden temperature change can distort fine mesh. Avoid steel wool and abrasive pads, which can damage the surface or bend the weave. Dry the chinois promptly, including around welds and the handle connection.
Inspect and store it
After washing, hold the mesh toward a light source to spot holes, bent sections, or trapped debris. Look again at welds and the handle joint. Replace or stop using a strainer if damage could let solids pass or make the tool unsafe to hold.
Store it where heavier cookware will not crush the cone. Do not stack objects inside it if they press on the mesh. A small dent may change the opening pattern even if the strainer still looks usable.
Clear Broth Service and Presentation
For a clean-looking broth, use the chinois as a controlled filter rather than a press. A coarse first pass removes large solids; a finer pass can catch smaller particles. This two-step approach can reduce clogging, but the result still depends on the broth and the mesh.
Practical kitchen setups
These examples show how mesh choice changes a straining workflow. They are not promises of a set drain time or a guaranteed clarity level; stock thickness, solids, and batch size all affect flow.
- Everyday chicken or vegetable stock: A 40-mesh screen with a nominal 0.385 mm opening is a reasonable starting point for separating cooked solids from liquid. Pour in batches and let gravity drain it.
- A broth needing a finer finish: Use a coarser first pass to remove bones and large pieces, then try a 60-mesh screen with a nominal 0.273 mm opening. Expect slower flow and watch for clogging.
- A screen that stops draining: Pause, reduce the batch, or clear the solids from the screen. Do not force liquid through. If a very clear result matters, use a finer secondary filter after the first pass.
Match the screen to the result
| Goal | Starting approach | Main trade-off |
|---|---|---|
| Separate large cooked solids | Coarser strainer before the chinois | More particles may pass into the next step |
| Strain everyday stock | 40 mesh, about 0.385 mm nominal opening | May not catch the finest suspended particles |
| Filter more finely | 60 mesh, about 0.273 mm nominal opening | Slower drainage; clogs more readily |
| Reduce cloudiness | Gravity drain; avoid pressing solids | Some liquid remains in the solids |
The useful buying question is not simply “How fine is this chinois?” Ask for the aperture and wire diameter, then consider how quickly you need to strain and how much cloudiness you can accept. If a seller gives mesh count alone, request the opening size before comparing it with another product.
Frequently Asked Questions
These short answers define the key terms and choices behind stainless broth chinois mesh. Product details can vary, so use a maker’s specifications for the exact model, especially for alloy, aperture, capacity, and temperature limits.
What is a stainless broth chinois?
It is a cone-shaped stainless strainer used to separate broth or stock from food solids.
What does 40 mesh mean?
It means about 40 openings along one linear inch of screen. It does not state the opening size by itself.
What is the opening size of 40 mesh?
With 0.25 mm wire, the nominal opening is about 0.385 mm. Actual product dimensions may vary.
What is the opening size of 60 mesh?
With 0.15 mm wire, the nominal opening is about 0.273 mm. Check the maker’s stated aperture.
Is 60 mesh better for broth?
Not always. It can catch smaller particles, but it drains more slowly and may clog sooner.
Should I press broth through a chinois?
Only if fuller extraction matters more than clarity. Pressing can push fine particles through and cloud the broth.
Can I pour boiling stock into a stainless chinois?
Stock may be near 100°C at sea level. Follow the manufacturer’s temperature limits, including those for handles and joints.
Can a chinois go in the oven or on induction?
It is a strainer, not cookware. Do not assume it has an oven rating or induction compatibility.
How should I clean fine mesh?
Use detergent and a soft brush, rinse well, and dry promptly. Avoid abrasive pads, steel wool, and cold-water shock while the mesh is hot.
What should I do if the mesh clogs?
Stop forcing liquid through. Use smaller batches, remove solids, or strain first through a coarser screen.
What is the key buying specification?
Ask for the actual opening size as well as mesh count. Also verify the stainless grade and food-contact claims with the manufacturer.
