Weber Workshops The EG-1 80mm Flat Burr Coffee Grinder

Weber Workshops EG-1 – 80mm Flat Burr Espresso Grinder

You slide the Blind Shaker off the oak plate. Two neodymium magnets precisely lock it into the correct position – no play, no fumbling. You load the dose into the funnel, press the button. The brushless motor starts, quietly, almost casually. You hear nothing sharp, no screeching, just a deep hum. The 80mm CORE burrs operate at the RPM you set – 900, 1200, 1800, depending on the bean and roast. The grounds fall into the shaker, which you shake briefly: the coffee powder distributes homogenously. You place it on the portafilter, flip it over. Puck. Clean. The same every morning. You look forward to the morning.

Since 2015, the Weber Workshops EG-1 has been the grinder against which others are measured. Douglas Weber, formerly part of Apple's product design team, conceived it as a single-dose espresso grinder for home baristas – with the explicit aim that it would be used for decades. The current Mk.3 version features 80mm CORE burrs (magnetically mounted, tool-free to change), variable speed from 500 to 1800 RPM, a PID-controlled motor for constant RPM, and retention under 0.1g. Coffee Coaching Club is the exclusive Swiss importer for Weber Workshops and carries the entire range including accessories and spare parts.

What the 80mm Flat Burrs Do in the Cup

The EG-1 grinds with 80mm CORE burr sets. This is not just a numbers game – size determines particle distribution. Smaller burrs (48mm, 54mm, 64mm) typically produce a larger proportion of very fine particles (fines) alongside the main particles. This is a bimodal distribution, which creates body, crema, and a certain sweetness in espresso.

80mm flat burrs work differently. The particle distribution is narrower, and the proportion of fines is lower. What becomes discernible in the cup: more clarity, more defined aroma separation, cleanly separated acidities. This does not mean that 80mm is automatically better – it means it produces a different result. Especially with lighter roasts and filter coffee crossovers, the difference is clear. Our observation after years of having the EG-1 in the showroom: those who want to hear the nuances of their bean will find more of them with the EG-1. This is one perspective, one of many.

The Further Developments

The current EG-1 is the third main generation. CORE (DB-1) burrs are the standard burr set for the Mk.3 and replace the previous BASE (DB-3) burrs – specially developed by Weber for a balanced character between clarity and body. For those who want even more specific profiles: the ULTRA (DB-2) burrs (sold separately) are optimized for maximum clarity in pour-over and filter. Other third-party alternatives, such as SSP sets, are available upon request.

Variable speed from 500 to 1800 RPM – adjustable in real-time during grinding. Lower RPM (around 800) tends to produce fewer fines and more clarity, higher RPM (around 1300) more body and texture. You can grind the same coffee in different ways without changing the grinder. The PID-controlled motor detects the resistance of the bean and adjusts the torque in real-time to maintain the set RPM even with hard beans. New in the Mk.3: a dedicated purge button in the center of the RPM dial, which briefly runs the burrs in reverse and then at maximum speed – to dislodge foreign objects or stuck beans and flush out any remaining coffee grounds.

Tool-Free Cleaning, Blind Shaker, Oak Plate

The lid of the EG-1 is held magnetically. You lift it off, the upper burr is also magnetically secured and can be removed without tools. Within 20 seconds, the grinding chamber is cleaned, and everything is back in place. This may sound like a small detail – but anyone who uses a grinder daily knows how much easy cleaning is worth in everyday life.

The Blind Shaker is a Weber in-house development, now used by world barista champions worldwide. A magnetically mounted collection cup with a special lid that homogenizes the grounds by brief shaking. The oak plate under the grinder precisely positions the shaker so that it stands exactly where it should during grinding.

At a Glance

Who is the EG-1 For?

The EG-1 is suitable for anyone looking for a grinder for the next ten to twenty years and willing to invest in a flagship-level tool. Home baristas who consciously single-dose and want to switch between different beans without rinsing. Cafes and roasters who want a grinder for competition use or for the bar.

The EG-1 is not for everyone. Those looking for an all-round grinder for various preparation methods will find a good choice at a significantly lower price with Varia (exclusive Swiss importer). Those seeking 80mm precision with more modern features like a pre-crushing system and auger feed will find a younger alternative in the Option-O Lagom P80. Those specifically looking to optimize for light roasts should check out the Option-O Lagom 01 with 102mm Blind Burrs. A detailed comparison of endgame options is available on the page EG-1 vs. Lagom P80 vs. Lagom 01.

The EG-1 remains the icon. The grinder with which Weber Workshops has shown that home grinding works at a commercial level. Those who want the tactile detail, longevity, and watchmaker-level craftsmanship will have something with the EG-1 that still feels good even after years. Those who want it know why.

What Goes Well With It

The EG-1 unfolds its potential with thermally stable espresso machines. The La Marzocco Linea Mini R with a saturated group head is the classic combination – both devices rely on stability and precision. The La Marzocco Linea Micra or the GS3 are also strong partners. For manual lever extraction: Flair Espresso 58+2 – the precision of the EG-1 particularly comes into its own with manual pressure build-up.

For brew-by-weight on the La Marzocco Mini R: the dedicated La Marzocco Connected Scale (sold separately) or the Acaia Lunar (USB-C, AL008+) with a Connected Scale license upgrade. For a standalone espresso scale with app and flow rate display: also Acaia Lunar (exclusive Swiss importer). For puck prep: Weber Workshops Moonraker as premium or Normcore WDT Tool as a more affordable option (exclusive Swiss importer). For airtight bean storage: Airscape (exclusive Swiss importer). For precise coffee water: Apax Labs mineral concentrates (exclusive Swiss importer). Background information on burrs, RPM, and particle distribution can be found in our Sensory World.

Frequently Asked Questions

What makes the 80mm burrs of the EG-1 special?

Larger burrs produce a narrower particle distribution with fewer fines for the same dose. This tends to lead to more clarity and defined aroma separation in the cup – especially noticeable with light roasts and filter coffee. In contrast, 48mm or 64mm burrs produce more fines and thus more body and crema. Both have their justification – the EG-1 specializes in clarity.

Can I change the burrs?

Yes. The CORE (DB-1) burrs are magnetically mounted and can be changed in under two minutes without tools. Official Weber alternatives: ULTRA (DB-2) for maximum clarity in filter coffee. SSP burrs and other third-party sets are available upon request. One grinder, multiple characteristics.

Is the EG-1 suitable for filter coffee?

Yes. The grind adjustment covers the complete range from espresso to coarse for French Press. With the CORE burrs, it works as an all-rounder; with the ULTRA burrs, it is particularly exciting for filter coffee and light roasts. If you are looking for a pure filter coffee specialist, the Timemore Sculptor 078 is a focused alternative.

How loud is the EG-1?

Quiet. The brushless motor operates without the high screeching of cheaper grinders, and the aluminum housing dampens vibrations. In our showroom, the EG-1 is in continuous use without disturbing conversations.

How long does an EG-1 last?

Weber Workshops builds with the explicit aim that the EG-1 will be used for decades. Wear parts such as wiper blades and cleaning pads are sold separately, and the burrs are interchangeable. In professional cafe use, wiper blades are changed approximately monthly; in home use, rarely. The construction itself is designed to last for generations.

Can I see the EG-1 before buying?

Yes. In the showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b), the EG-1 is in daily use. Weight, running noise, cleaning, and haptics cannot be conveyed through photos. You are welcome to bring your own beans.

How quickly is the EG-1 delivered in Switzerland?

2 to 4 working days throughout Switzerland and Liechtenstein. Click and Collect in Bern and Zurich recommended. Financing via Heylight is possible.
