How to Tell If Wood Is Teak: 6 Checks, 2 Myths to Skip

To tell if wood is teak, check the pores, not the weight. Real teak (Tectona grandis) is a golden to medium brown wood with coarse, mostly straight grain, large open pores in a ring-like pattern, a slightly oily feel, and a leather-like smell when freshly cut. Its look-alikes, iroko and afrormosia, have a different pore structure, and neither weight nor hardness will separate them from the real thing.

Most guides say real teak feels heavy and hard. It does not, at least not compared with other hardwoods, and that advice sends buyers toward the wrong wood. This guide uses figures from the Wood Database teak profile and its profiles of the common substitutes to give you six checks that hold up, two popular tests that do not, and a quick way to test a finished piece of furniture without wrecking it.

Quick Answer: What Real Teak Looks Like

Wood Database describes teak heartwood as golden or medium brown that darkens with age, with straight grain that is occasionally wavy or interlocked, a coarse and uneven texture, and only moderate to low natural luster. Teak is rated very durable and is often called the gold standard for decay resistance. That combination explains why it shows up on boat decks, outdoor tables, and workshop benches, and why sellers are tempted to stretch the name to cheaper woods.

If a piece matches that description, check it against the six tests below. One match proves nothing. Three or four that all agree, including the pore check, is strong evidence.

Why the Usual Advice Fails: Teak Is Not Heavy or Unusually Hard

Search results are full of “teak is dense and heavy, so lift it and see.” Look at the published numbers instead. Teak weighs about 40.9 lb per cubic foot dried and has a Janka hardness of 1,070 lbf. White oak, the wood most people picture when they think “solid hardwood,” weighs 47.0 lb per cubic foot and measures 1,350 lbf. Teak is a medium-weight, medium-hardness wood that gets its reputation from oils and decay resistance, not from brute density.

Wood	Janka hardness (lbf)	Dried weight (lb/ft3)	Pore structure
Teak	1,070	40.9	Ring-porous or semi-ring-porous
Iroko	1,190	41.2	Diffuse-porous
Afrormosia	1,570	45.3	Diffuse-porous
White oak	1,350	47.0	Ring-porous
Dark red meranti (Shorea)	800	42.0	Diffuse-porous

Two things jump out. First, teak and iroko differ by only 0.3 lb per cubic foot, so no scale or “feels heavy” test can tell them apart. Second, the last column is the only one where teak separates cleanly from its two best-known substitutes. That is why the pore check comes first in the list below.

The 6 Checks That Actually Work

1. Look at the pores (the most reliable check)

Wood Database lists teak as ring-porous or semi-ring-porous, with large to very large pores in the earlywood and medium to large pores in the latewood, few in number. Tyloses and whitish deposits, which are silica, are common inside those pores. Iroko and afrormosia are both listed as diffuse-porous, meaning the pores are spread fairly evenly across the growth ring with no obvious band of large pores.

To check, use a sharp blade or fine sandpaper on a hidden end-grain surface and look with a 10X loupe. In teak you should see the larger pores clustered along the growth rings with smaller ones between them, sometimes with pale specks inside. In a diffuse-porous look-alike the pores look more uniform across the surface. The pore check is not foolproof on tiny samples or on badly sawn surfaces, but it is the one difference that comes from the species themselves rather than from the finish or the age of the wood.

2. Judge the color and how it ages

Fresh teak heartwood runs golden to medium brown and darkens with time. Sapwood is much paler, so a board with a lot of pale edge is a sign that the maker cut cheaply. Left outdoors without oil, teak weathers to a silver-gray. Color alone is a weak test, though: iroko is described as yellow to golden or medium brown and also darkens, and afrormosia is yellowish brown, sometimes with a reddish or olive cast. Treat color as a filter, never as proof.

3. Read the grain and texture

Teak grain is usually straight, sometimes wavy or interlocked, with a coarse, uneven texture and a low luster. Iroko is different in a useful way: its grain is interlocked and sometimes irregular, with a medium to coarse texture and good luster, so it can look shinier and more ribbon-striped. Afrormosia has a finer, more uniform texture. If the surface looks smooth and glassy with tight, even grain, you are probably not looking at teak.

4. Smell a freshly cut or sanded spot

Wood Database notes that teak can have a leather-like scent when freshly milled. That is the “new baseball glove” description you see online. The keyword is fresh: a varnished, oiled, or years-old surface will smell of the finish, so scrape or sand a hidden spot first. Smell is also a supporting clue only, because afrormosia is listed with a distinct odor of its own while being worked, and iroko is listed with no characteristic odor. If you want a reference, our guide on what different woods smell like covers the common ones.

5. Feel for a slightly oily surface

Unfinished teak often feels slightly oily or greasy because of its natural oils. This is a real trait, but it is easy to fake and easy to lose. A “teak oil” finish can be rubbed into almost any wood and will make it feel and look richer, and old teak that has weathered gray no longer feels slick on the surface. Test an unfinished edge or the underside, and compare against a piece of wood you already know, such as an oak or pine offcut.

6. Notice what it does to your tools

Teak contains silica, up to about 1.4 percent according to Wood Database, and it has a pronounced blunting effect on cutting edges. If a saw blade or plane iron dulls faster than its hardness would predict, that fits teak. It also fits iroko, which can contain calcium carbonate deposits with a significant dulling effect, so this is a confirming clue rather than a deciding one. Wood Database also notes teak may need a solvent wipe before gluing or finishing because of its oils. If you are planning a build, that matters more than identification, and our article on how to apply teak oil covers the finishing side.

Two Popular Tests You Can Skip

• The weight test. As the table shows, teak is lighter than white oak and nearly identical to iroko. Lifting a board tells you almost nothing about the species.
• The water-drop test. Beading water is often described as proof of teak. In practice it depends more on the surface than the species: a sanded, waxed, oiled, or sealed piece of almost any wood can bead water for a while. Use it, if at all, as a weak hint on a bare surface, never as a deciding test.

Teak vs Its Common Look-Alikes

Iroko

Wood Database says iroko (Milicia excelsa and M. regia) is sometimes used or marketed as a low-cost alternative to teak, and that it is stable, durable, and somewhat resembles teak. Tell it apart by the diffuse pores, the interlocked and more lustrous grain, and the lack of a leather-like scent. Iroko can also cause eye, skin, and respiratory irritation in sensitive people, so wear a dust mask when sanding it. We compare the two in detail in Iroko vs Teak.

Afrormosia

Afrormosia (Pericopsis elata) is marketed as a teak substitute and is described as similar in weight, strength, and appearance, with nearly comparable rot resistance. It is diffuse-porous with a finer, more uniform texture than teak. Wood Database also notes that afrormosia is itself threatened and CITES protected, so a seller offering it as a bargain teak is a double red flag for the buyer.

Teak-look composites and stained hardwoods

Some products sold as teak-look are composites, tiles, laminates, or a different hardwood stained golden brown. Composites have no real end grain and a repeating pattern, and stained wood shows raw color where it is scratched or drilled. If the grain pattern repeats at regular intervals, it is printed or molded, not grown.

Real teak also comes with grades and origins, from old-growth Burmese to plantation-grown lumber. If you are chasing a specific origin, see how to identify Burma teak, and for why prices vary so much, read why teak is so expensive.

How to Test Teak That Is Already Finished

Most furniture arrives sealed, oiled, or varnished, which hides the feel and the smell. You still have options:

• Find a hidden surface. The underside of a tabletop, the inside of a drawer, or the back of a leg is usually less finished than the visible face.
• Look at end grain. A cut end, a tenon, or a table edge shows pores through most clear finishes. This is where the loupe earns its price.
• Ask for the species name. A reputable seller should be able to say Tectona grandis, and where it was grown. Vague answers such as “teak-type” or “teak finish” are a warning.
• Do not sand through paint or stain on a piece you do not own. Ask permission first.

If you own the piece and want it to look its best, our guides on treating teak furniture and restoring weathered teak pick up where identification leaves off.

Step-by-Step: A 5-Minute Teak Check

1. Find a hidden spot such as an underside, drawer interior, or cut end.
2. Clean a small patch with fine sandpaper so you are looking at bare wood, not finish.
3. Smell the sanded patch. A leather-like scent is a point for teak; a sharp resinous or no scent is neutral or against.
4. Feel the bare surface for a slightly oily texture, and compare with a known wood.
5. Look at the pores with a 10X loupe. Large pores clustered along the growth rings point to teak; evenly scattered pores point to iroko, afrormosia, or something else.
6. Check color and grain against the descriptions above.
7. Count the matches. Three or four consistent signs, including the pores, is a confident yes. Anything less, treat it as unconfirmed.

FAQ

Is teak heavy or very hard?

No. Wood Database lists teak at about 40.9 lb per cubic foot and 1,070 lbf on the Janka scale, which is lighter and softer than white oak at 47.0 lb and 1,350 lbf. Teak’s reputation comes from its oils and decay resistance, not from extreme density.

How can I tell teak from iroko?

Look at the pores and the grain. Teak is ring-porous or semi-ring-porous with a coarse, uneven texture, while iroko is diffuse-porous with interlocked, more lustrous grain. Weight will not help because the two are almost identical at about 41 lb per cubic foot.

Does real teak smell like leather?

Freshly milled or freshly sanded teak can have a leather-like scent, according to Wood Database. A finished or weathered surface will not smell of it, so test a bare hidden spot, and treat smell as a supporting clue only.

Can I identify teak if it has been oiled or varnished?

Partly. The feel and smell are hidden, but the end grain and a hidden bare spot still show the pore structure and color. Checking for pore arrangement with a 10X loupe is the most reliable method on finished pieces.

Is teak oil made from teak?

Not necessarily. Teak oil is a finish sold for teak and many other woods, and applying it does not make a piece teak. An oily look from a recent oiling is one reason the feel test alone is unreliable.
