Timemore E&B Burr: What It Is, How It Performs, and Who It Is For

The Timemore E&B burr is a specialty burr set designed to work across both espresso and brew (filter) coffee. The name literally stands for "Espresso and Brew." Unlike standard burrs that are optimized for one end of the grind spectrum, the E&B aims to deliver good performance whether you are pulling shots or making pour over. After using the E&B burr in my Timemore Chestnut X for several months, I can say it delivers on that promise, with some caveats.

Most hand grinders come with a single burr set that tries to cover everything but compromises somewhere. You either get great espresso performance with mediocre filter results, or smooth pour over grinds with too many fines for espresso. The E&B burr is Timemore's attempt to close that gap. It uses a specific cutting geometry on the stainless steel surfaces that produces a more bimodal particle distribution for espresso and a tighter unimodal distribution for coarser filter settings.

How the E&B Burr Differs From Standard Timemore Burrs

Timemore uses several burr designs across their grinder lineup. The most common are the S2C (standard in the C2 and C3) and the E&B (available as an upgrade or stock in premium models). Understanding the difference helps you decide if the E&B is worth the investment.

S2C Burrs (Standard)

The S2C burrs use a simpler cutting geometry that prioritizes consistency at medium and coarse settings. They perform well for pour over, French press, and drip. At espresso-fine settings, S2C burrs produce a wider particle distribution with more fines, which can lead to channeling and muddy flavors in your shots.

E&B Burrs (Premium)

The E&B burrs have a more complex tooth pattern that changes behavior depending on grind size. At fine settings (espresso), the geometry produces a moderate amount of fines alongside a concentrated peak of target-size particles. This bimodal distribution is actually what you want for espresso. The fines slow down water flow through the puck, creating resistance and allowing for proper extraction.

At coarser settings (pour over and filter), the E&B burrs shift toward a unimodal distribution, meaning most particles are the same size with fewer outliers. This produces a clean, sweet cup without the muddiness that excessive fines cause in filter coffee.

The Practical Difference

In my testing, the E&B burr improved my espresso shots noticeably compared to the S2C. Shots had more clarity in the flavor, better body, and less astringency. The difference on pour over was smaller but still present. My V60 drawdown times became more consistent, and the cups had a touch more sweetness.

If you only brew filter coffee, the S2C is perfectly fine. If you split your time between espresso and filter, the E&B is worth the upgrade.

Which Timemore Grinders Use the E&B Burr?

The E&B burr is available in several configurations:

Stock E&B burrs: The Timemore Chestnut X and some limited edition models come with E&B burrs installed from the factory.

Upgrade option: You can purchase E&B burr sets separately and install them in compatible Timemore grinders. The most common upgrade path is swapping the S2C burrs in a C2 or C3 for E&B burrs.

Compatibility: The E&B burrs fit any Timemore grinder that uses the 38mm burr size, which includes the C2, C3, Slim, Slim Plus, and Chestnut series. Make sure you order the correct size if you are upgrading. Timemore also makes 42mm and larger burrs for their premium models, so double-check compatibility before purchasing.

Cost of the Upgrade

A standalone E&B burr set runs about $25 to $40 depending on the seller. For a C2 owner, that means your total investment goes from $65 to about $90 to $105. At that price, you start overlapping with the 1Zpresso Q2 and JX, which are worth considering as alternatives. For a full comparison, check our best burr coffee grinder roundup.

Installing the E&B Burr

Swapping burrs in a Timemore grinder is straightforward and takes about 10 minutes. Here is the process.

Step by Step

Remove the bottom catch cup by unscrewing it
Unscrew the outer burr retaining ring (counterclockwise)
Lift out the outer burr
Note the orientation of the old burr (there is a flat edge that aligns with a notch in the body)
Place the new E&B outer burr in the same orientation
Screw the retaining ring back on firmly
Reassemble the grinder

The inner burr is press-fit onto the shaft and does not need to be replaced separately in most cases. The E&B upgrade kit usually includes just the outer burr, as that is where the geometry change matters most.

After Installation

Re-calibrate your zero point by tightening the adjustment until the burrs touch. Then season the new burrs with 50 grams of cheap beans. Your click settings will change after the swap, so do not assume your old V60 or espresso settings still apply. Start fresh and dial in again.

Grind Performance Testing

I ran the E&B burr through three brew methods to see how it performs in practice.

Espresso (12 Clicks on Chestnut X)

I pulled shots on a Flair Pro 2 using 18 grams in, targeting 36 grams out in 25 to 30 seconds. With the S2C burr, I had to grind at 10 clicks to hit that range, and the shots often channeled. With the E&B at 12 clicks, I consistently hit 28-second shots with less channeling. The flavor profile was cleaner, with more defined acidity and a smoother finish.

The E&B does not turn a hand grinder into a Niche Zero. But it closes the gap meaningfully. My shots went from "okay for a hand grinder" to "I am actually enjoying this."

V60 Pour Over (20 Clicks)

Using my standard 15g:250g recipe, the E&B burr produced a drawdown time of 2 minutes 50 seconds compared to the S2C's 3 minutes 5 seconds at the same relative setting. This tells me the E&B produces fewer fines at pour over settings, allowing water to flow more freely through the bed.

The cup tasted slightly brighter and sweeter. The clarity improvement was subtle but consistent across multiple brews with different beans.

French Press (26 Clicks)

At coarse settings, the difference between E&B and S2C was minimal. Both produced a clean French press with acceptable sediment levels. If French press is your primary method, the E&B upgrade probably is not worth the cost.

E&B Burr vs. Competitors

The E&B burr is not the only option for improving a budget hand grinder's performance. Here is how it compares to the alternatives.

Timemore E&B vs. Stock 1Zpresso Q2 Burrs

The 1Zpresso Q2 uses its own proprietary burr design that performs well across the grind spectrum. In my side-by-side testing, the Q2's stock burrs were comparable to the E&B at espresso settings and slightly behind at pour over. For the total price (C2 + E&B upgrade versus Q2), the Q2 is a better value since you also get a better adjustment mechanism and overall build quality.

Timemore E&B vs. Comandante Standard Burrs

The Comandante uses Red Clix burrs that are widely regarded as some of the best in the hand grinder world. The E&B cannot match the Comandante's consistency, especially at filter settings. But the Comandante costs $250 versus $90 for a C2 with E&B burrs. For the price difference, the E&B is a strong performer.

When to Buy the E&B vs. A New Grinder

If you already own a Timemore C2 or C3 and want better espresso performance, the $30 E&B burr upgrade makes more financial sense than buying a new grinder. If you are starting from scratch and want the best all-around performance under $100, buying a 1Zpresso Q2 or JX with stock burrs is a better move. Check out our best burr grinder picks for a detailed comparison.

Maintenance and Longevity

The E&B burrs are made from the same stainless steel as the S2C burrs and should last just as long. With regular home use (15 to 30 grams per day), expect several years of service before any noticeable dulling.

Clean the E&B burrs the same way you would any Timemore burr set. Brush out retained grounds after every few uses, and do a monthly deep clean with a dry cloth. The more complex tooth geometry of the E&B burr can trap coffee particles in the grooves, so pay extra attention during cleaning. A toothpick or wooden skewer helps clear grounds from the deeper cuts in the burr surface.

FAQ

Is the Timemore E&B burr worth upgrading to?

If you primarily brew espresso and filter coffee, yes. The improvement at espresso settings is significant, and the filter performance is slightly better too. If you only brew French press or cold brew, the standard S2C burrs are perfectly adequate and you can save the $30.

Can I put E&B burrs in my Timemore C2?

Yes, as long as you buy the correct 38mm E&B burr set. The installation is simple and reversible. You can always swap back to the original S2C burrs if you prefer them.

Do E&B burrs change the click settings?

Yes. After installing E&B burrs, your old grind settings will not produce the same results. You need to re-calibrate your zero point and dial in your settings for each brew method from scratch.

How do E&B burrs compare to flat burrs?

The E&B is still a conical burr. Flat burrs (found in grinders like the DF64 or Eureka Mignon) generally produce a more unimodal distribution, which some people prefer for filter coffee. The E&B is Timemore's best attempt at bridging conical and flat burr characteristics in a conical format. It is a meaningful improvement over standard conical burrs but does not fully replicate the flat burr experience.

The Bottom Line on E&B Burrs

The Timemore E&B burr is a smart upgrade for anyone who already owns a compatible Timemore grinder and wants better espresso performance without buying a new grinder. For $30, you get a noticeable improvement at fine settings and a slight boost at filter settings. If you are shopping for a new grinder entirely, factor the E&B upgrade cost into your comparison. A C2 plus E&B burrs at $95 total competes directly with the 1Zpresso Q2, and both are solid choices for an all-around hand grinder.
