Weber Workshops EG-1 burrs – Core and Ultra (DB-2)
The EG-1 was developed around its burrs. That's why there are several burr sets, each enabling a different grind profile with near-zero retention. Here you'll find the two main sets, as a replacement or to swap between.
The Core (DB-1) shipped with the EG-1 Mk.3. According to Weber, the new EG-1 (October 2026) is available with either Core or Ultra fitted at the factory. Coffee Coaching Club is the official Swiss importer of Weber Workshops.
The two sets
Core (DB-1)
The all-rounder among the EG-1 burrs. Weber recommends the Core if you want to grind espresso as well as filter coffee. Weber describes its particle distribution as medium fines.
Ultra (DB-2)
Built for filter coffee. Weber has the Ultra made by SSP. According to Weber, it produces low fines and is designed for separation and clarity in the cup. According to Weber, it is not suitable for espresso.

Which set suits you
The Core is the familiar factory configuration. If you'd like to shift the character of the grind deliberately towards more clarity, have a look at the Ultra (DB-2). According to Weber, the Ultra is made for filter coffee and is not suitable for espresso.

Frequently asked questions
Which set is fitted in my EG-1?
The EG-1 Mk.3 shipped with the Core (DB-1). According to Weber, the new EG-1 (October 2026) is available with either Core (DB-1) or Ultra (DB-2) fitted at the factory. Both sets are also sold separately.
Can I change the burrs myself?
Swapping them is intended and takes careful work; on the EG-1 up to Mk.3, adjustment afterwards is part of it. On the new EG-1 (October 2026), according to Weber, Intrinsic Alignment means no manual alignment is needed after a burr change. If you're unsure, our team will help you.
How do Core and Ultra differ?
The Core is the balanced standard; the Ultra (DB-2) is designed for more separation and clarity.
Do the burrs fit the new EG-1?
Yes. Weber offers the Core (DB-1) and Ultra (DB-2) as a second set when you buy the new EG-1 (October 2026) and lists the EG-1 burrs as an accessory on its product page.
Roastery tip: After a burr change, new burrs need a few runs to bed in – go ahead and grind through the first doses and readjust the grind size before you judge the shot. That's our recommendation, one of many.
