Mahlkönig E80W GBS/GBW Espresso Grinder

Key Features

• Grind-by-Weight dosing: A built-in load cell weighs the grounds 6,000 times a second, so every dose is exact across staff and shifts. 
• Grind-by-Sync with automatic adjustment: Pairs with a compatible espresso machine or the Mahlkönig Sync Scale and nudges grind size towards your target extraction time. 
• 80mm cast steel burrs: Grinds 6-7g per second in the UK, so a double shot is ready in around 3 seconds. 
• Tool-free zero calibration: Recalibrates in about 10 seconds from the touchscreen, rather than 10+ minutes by hand. 
• Disc Distance Detection and portafilter detection: Repeatable grind settings, and the grinder recognises each portafilter to load the right recipe. 
• Active temperature control: A cooled motor keeps grind quality steady through back-to-back peak service, and it runs quietly too.

Frequently Asked Questions

What's the difference between the E80W GbS and the E80S GbW?

The Mahlkönig E80W GbS (Grind-by-Sync) is the newer model and replaces the E80S GbW (Grind-by-Weight). It keeps full Grind-by-Weight dosing and adds Sync connectivity, electrical burr adjustment and the Mahlkönig Sync app. 

Should I choose the E80W or the E65W?

Go for the E80W if you run a very busy bar: it grinds faster, and its burrs last around three times longer. The Mahlkönig E65W suits moderate volumes or tighter counters, as it’s narrower and lighter. 

Do I need a Sync-compatible machine to use this grinder?

No. The E80W works fully as a standalone Grind-by-Weight grinder with any of our commercial espresso machines or your existing setup. Sync simply adds automatic grind adjustment when paired with a compatible machine. 

How often do the burrs need replacing?

The burrs are rated for around 2,500kg of coffee at the median setting. That’s roughly 138,000 double shots at 18g, so a café pulling 300 doubles a day gets well over a year from a set. 

Does it need to be plumbed in?

No plumbing required. It’s a standard plug-in unit on a regular UK socket. 

Can new baristas use it without much training?

Yes. Weight-based dosing and the on-screen assisted dial-in take the guesswork out, so new staff pull consistent shots quickly. Want your team to go further? Take a look at our barista training courses.
