Weber Workshops EG-1 Coffee Grinder – The Icon of the Single-Dose Revolution
The Weber Workshops EG-1 isn't just a grinder – it's the grinder that started the single-dose revolution in 2015. With 80mm CORE flat burrs, variable RPM control, 5-micrometer stepped adjustment, and the legendary blind shaker, the EG-1 still sets the standard today. As an official Weber partner in Switzerland, we offer you access to this iconic grinder.
Why the EG-1 is legendary
As a coffee roastery, we have a clear opinion: The EG-1 is not the perfect grinder. It's expensive, it can stall with hard beans and low RPMs, and it's heavy (13.5 kg). But despite all these "drawbacks," for many it's the best grinder ever made. Why?
Because the EG-1 perfected the concept of the single-dose grinder before anyone else even thought of it. Variable RPM (2015 – years before anyone else), 5-micrometer stepped adjustment (unrivaled in precision), near-zero retention (<0.1g), and the blind shaker – a tool that has changed the way we dose coffee.
The EG-1 isn't for everyone. If you're looking for a grinder that simply works, get the Varia VS4 . If you want flexibility with interchangeable burrs, get the Varia VS6 . If you want 80mm precision at a better price, get the Option-O Lagom P80 .
But if you want the icon, the original, the grinder used by barista champions worldwide, the grinder with which Weber Workshops proved that home grinding can work at a commercial level – then you want the EG-1.

The Blind Shaker: Weber's Game-Changer
The EG-1 comes with the Blind Shaker – a Weber innovation now used by barista champions worldwide. What makes it so special?
The Blind Shaker is a magnetically mounted collection cup with a special lid. You grind directly into the shaker, put the lid on, and shake. Shaking does three things:
- Reduces static (fluffier flour, less clumping)
- Homogenizes particle distribution (less channeling)
- Increases extraction yield (measurably better shots)
In practice? We use the blind shaker daily in the roastery. With our Cozy Chocolate , the difference between "without shaker" and "with shaker" is about 0.5% TDS – that's noticeably more body and sweetness.
The Blind Shaker is now so popular that Weber sells it separately . But with the EG-1, you get it included – perfectly matched to the grinder.
Variable RPM with PID controller: The Weber magic
The EG-1 was the first commercially available grinder with variable RPM in 2015. That alone is impressive. But what really makes the EG-1 special is its PID controller.
The PID controller "senses" the hardness of your beans in real time and dynamically adjusts the RPM to maintain your target RPM. Hard, light beans? The motor delivers more power. Soft, dark beans? Less power. The result: constant RPM, constant particle distribution.
Recommended starting RPM range: 1600 for espresso. We grind our Nutty Delight at 1700 RPM – the perfect compromise between clarity and body. For pour-over, we go down to 800-1000 RPM for higher throughput.
A word of warning: The EG-1 can stall with very hard beans and very low RPMs (below 500). The 315W motor isn't the most powerful (the Lagom P80 has 500W). But for 99% of applications, this isn't a problem – just stay within the recommended RPM range.
5-micrometer stepped adjustment: Precision like a scalpel
The EG-1 has a 5-micrometer stepped adjustment – that's 0.005 mm per step. For comparison: The Varia VS6 has 5 micrometers, the Lagom P80 has 10 micrometers.
What does that mean in practice? If you have a perfect shot and only want to make minimal adjustments – one step, 5 micrometers, that's enough. No overshoot, no undershoot. Surgical precision.
We use this precision daily: When a new roast is freshly roasted (days 1-3), it's harder. We coarsen the grind by 2-3 steps. After 7-10 days of degassering, we go back to a finer grind by 2-3 steps. That's a total of 10-15 micrometers – tiny changes, but they make a noticeable difference.
EG-1 vs. Lagom P80 vs. Varia VS6
We are often asked: EG-1, Lagom P80 , or Varia VS6 ? All three are top-tier, but for different users:
EG-1: The icon. 80mm CORE Burrs, Blind Shaker, 5-micrometer adjustment, legendary status. More expensive, heavier, but the original. For people who want the best, regardless of price.
Lagom P80: A modern alternative. 80mm mizen burrs with a pre-crushing system, 500W motor (more power), and a lower price. For those who want 80mm precision at a better price-performance ratio.
Varia VS6: Modular concept. Interchangeable burrs (flat vs. conical), variable RPM, compact design. For those who enjoy experimenting and prioritize flexibility over specialization.
Who is the Weber EG-1 right for?
EG-1 is for you if you:
- Want to own the original single-dose revolution?
- If you want to use the Blind Shaker (game-changer for dosing)
- 5-micrometer precision estimates (surgical dialing-in)
- You only want the best
The EG-1 isn't the cheapest, the most compact, or the most powerful. But it's the grinder that started it all. And it's still damn good.
A typical workflow with the EG-1
7:00 AM: You weigh out 18.5g of Cozy Chocolate . The RPM dial is set to 1600. Place the bean dish on, hot start (the grinder is already running), add the beans. Grind for 9 seconds, done. Press the clicker (purge last granules).
The flour goes into the blind shaker. Put the lid on and shake 3-4 times. The flour is now fluffy, homogeneous, and static-free. You pour it into your portafilter using the normcore dosing funnel and distribute it with the subminimal flick .
Extraction on your Linea Mini R : 1:2.5 ratio, 93°C. The shot tastes of chocolate, hazelnut, and caramel. Perfectly balanced, no bitterness, creamy texture. This is the EG-1.

Frequently asked questions about the Weber EG-1
Is the EG-1 worth it compared to the Lagom P80 ?
Technically, the P80 probably offers better value for money (500W motor, pre-crushing system, cheaper). But the EG-1 is the icon, the original, with the legendary blind shaker. If status and history are important to you: EG-1. If technical specs are more important: P80. Come by, we'll show you both.
Can the EG-1 really stall?
Yes, it can stall with very hard beans (e.g., very light roasts, Kenya AA) and very low RPMs (below 500). The 315W motor isn't the most powerful. Solution: Stay within the recommended RPM range (1000 and above for espresso), then there won't be any problems. We haven't had a single stall in two years.
Which Burrs should I choose: CORE or ULTRA?
CORE filters are suitable for both espresso and filter coffee (all-rounders). ULTRA filters are specialized for filter coffee (minimal fines, maximum clarity) but are not suitable for espresso. For 90% of users: CORE. Only if you exclusively use pour-over: ULTRA.
Is the EG-1 really that easy to clean?
Yes. Funnels open (magnetically), Burr chamber accessible in 20 seconds, clear it out, close it again. 30 seconds total. No tools needed. It's really true.
EG-1 Silver or Onyx?
It's purely a matter of taste. Silver is classic, black is modern/stealthy. Technically identical. We have both in the showroom – come by and see which one you prefer.

Coffee Roastery Tip: The EG-1 with the blind shaker is a revelation with our Nutty Delight blend. At 1600 RPM with CORE Burrs, you get a balance that's hard to beat – the hazelnut notes are precise, the caramel sweetness is fully present, and the blind shaker adds a creaminess to the texture that you could never achieve without it. Shaking homogenizes the particle distribution so effectively that channeling becomes virtually impossible. Also try Cozy Chocolate at 700 RPM – the chocolate sweetness becomes so creamy with the blind shaker that you'll think you're drinking milk chocolate. For the adventurous: Wild Peach at 700 RPM with CORE Burrs (or better yet, ULTRA Burrs for filter coffee) – the clarity is breathtaking, every fruity note stands on its own, and the blind shaker prevents clumping, which is often problematic with lighter roasts.
