The Short Version
That uncharacteristic sourness in your cup isn’t a bad roast—it’s likely a fractured burr ring sabotaging your grind geometry. While 3D printing offers a quick fix, a $5 official replacement is the only way to ensure the mechanical alignment your brew demands.
If your coffee tastes uncharacteristically sour despite high-quality beans, the culprit might be a microscopic mechanical failure rather than your roast profile. When a Baratza Encore produces an uneven grind—mixing fine dust with larger chunks—the issue often traces back to a fractured burr ring. This small component is vital for maintaining the alignment necessary for uniform particle size.
I did the print out, replaced the ring, and the Encore was grinding evenly again.
Identifying the mechanical failure
The symptoms are unmistakable during the brewing process. Inconsistent extraction caused by poor grind geometry leads to acidity and a lack of body in drip brewers like the Bonavita. Upon inspection, you will likely find that one of the small tabs on the burr ring has snapped off. I did the print out, replaced the ring, and the Encore was grinding evenly again. This structural failure prevents the burrs from sitting perfectly parallel, sabotaging even the most precise brewing equipment.
Temporary fixes and long-term stability
3D printing offers an immediate workaround if you have access to a printer and files from sites like MakerWorld. However, using PLA filament may not withstand the long-term friction and vibration of daily operation. For those seeking permanent stability, there is a clear cost-benefit: while a DIY print is essentially free, ordering official replacement rings directly from Baratza costs only about $5. This minimal investment ensures the grinder’s long-term reliability compared to the uncertainty of plastic filaments.

Questions & Answers
Why does a broken burr ring cause inconsistent coffee flavor?
A broken burr ring causes inconsistent coffee flavor because it prevents the grinding burrs from sitting perfectly parallel to one another. When the structural integrity of the ring is compromised, such as when a small tab snaps off, the grinder produces an uneven mix of fine dust and large chunks. This poor grind geometry leads to inconsistent extraction during the brewing process, which often results in coffee that tastes uncharacteristically sour and lacks necessary body.
How can you identify if your Baratza Encore has a fractured burr ring?
You can identify a fractured burr ring by looking for unmistakable symptoms of uneven grinding during your brewing process. If your coffee tastes unusually sour despite using high-quality beans, the issue likely stems from inconsistent particle sizes produced by poor grind geometry. Upon a physical inspection of the grinder's internal components, you will typically find that one of the small tabs on the burr ring has snapped off, disrupting the alignment needed for uniform grinding.
What are the pros and cons of 3D printing a replacement burr ring?
The main advantage of 3D printing a replacement burr ring is that it offers an immediate, essentially free workaround if you have access to a printer and digital files. However, using 3D-printed parts like PLA filament carries significant risks regarding long-term stability. These plastic filaments may not be able to withstand the constant friction and vibration produced during daily grinder operation. This makes a DIY print less reliable than purchasing an official part for permanent mechanical stability.
How much does it cost to replace a Baratza Encore burr ring?
Ordering an official replacement burr ring directly from Baratza costs approximately five dollars. While 3D printing provides a free temporary fix, this minimal financial investment ensures the long-term reliability and mechanical integrity of your grinder. Choosing an official part avoids the uncertainty associated with plastic filaments that might fail under heat or vibration. Investing in the genuine component is a cost-effective way to ensure your grinding burrs remain perfectly aligned for consistent brewing results.
