The Fellow Opus 2 is a good fit if you want small espresso adjustments and filter coffee from one grinder. Its continuous dial suits brewers willing to refine a recipe and keep notes when switching methods.
Skip it if your goal is simply to repeat the same pot of coffee with minimal adjustment. The OXO Brew offers a remembered timer setting, while the Baratza Encore and Encore ESP give you defined grind positions.
Who should buy the Fellow Opus 2?
Buy the Fellow Opus 2 if espresso and filter coffee both matter in your kitchen. Its main advantage is the freedom to make small grind changes without jumping between fixed settings.
Fellow Opus 2: Best for mixed brewing households
- 48 mm conical burrs
- Stepless grind adjustment
- Espresso to cold brew range
- Two magnetic catch cups
- Automatic shutoff
Choose it for small espresso adjustments and a routine that also includes filter coffee. Recording dial positions helps when moving between brew methods.
Pros
- Continuous adjustment for small grind changes
- Separate catch cups for coarse grounds and espresso
- Automatic shutoff
- Tool-free burr access
Cons
- Returning to an exact position takes care
- Frequent method changes require more dial adjustment
The Opus 2 uses 48 mm conical burrs and covers espresso, pour-over, drip coffee, French press and cold brew. That range suits a household sharing one grinder across several brewers.
It also suits someone who weighs beans before each brew and changes coffees often. Fellow describes its retention as near zero, meaning the design aims to leave little ground coffee behind between doses.
When should you skip the Fellow Opus 2?
Skip the Opus 2 if you prefer defined settings to continuous adjustment. A numbered stepped position is easier to communicate between household members than a carefully noted point on a continuous dial.
Frequent switching also has a practical cost: you must return to each recipe's starting position and check the next brew. A wide grind range gives you options, but it doesn't remove that work.
For a kitchen devoted to one filter method, simpler controls may matter more than fine espresso adjustment. Spend your attention on a repeatable recipe rather than buying adjustment freedom you won't use.
What does stepless adjustment change?
Stepless adjustment lets you choose a grind position between fixed steps. This is most useful for espresso, where a small grind change can alter how quickly water passes through the coffee.
A stepped grinder gives you a set of positions to select. With a continuous dial, you can make a smaller move when one setting flows too quickly and a slightly finer position slows the shot too much.
That extra freedom also calls for restraint. Make one small change, brew again and judge the result before moving the dial further.
Record the coffee, dose, dial position and drink weight when a recipe works. A photo of the dial can help you return close to the same position after making another brew method.
The espresso grind size guide explains how grind affects extraction. For a starting point across several brewers, use the coffee grind size chart.
How does the Fellow Opus 2 compare with stepped grinders?
The Fellow Opus 2 suits brewers who want control between steps; stepped grinders suit those who prefer fixed reference points. Neither approach removes the need to adjust for different beans.
A fixed number helps you repeat a setting, but it isn't a universal recipe. Roast level, coffee age, dose and brewer can all change the grind you need.
The Baratza Encore vs Fellow Opus comparison explores that choice. If you want espresso adjustments with numbered positions, the Baratza Encore ESP review is the closer alternative.
How should you set up the Opus 2?
Start with one coffee and one familiar brew recipe. Learning the grinder is easier when you aren't also changing beans, water amounts and brewing methods.
Place it on a dry, stable counter with room to remove the lid and catch cup. Its dimensions are 7.95 x 5.12 x 10.49 in, but overhead clearance matters as well as the space it occupies.
Before the first grind, follow Fellow's assembly and preparation instructions. Use the guide under the lid to choose an initial position, then follow the manual's directions for moving between coarse and fine settings.
Weigh a modest amount of coffee for your first brew instead of grinding a large batch. Keep these recipe notes:
- Coffee and roast level.
- Bean dose and water amount or target drink weight.
- Dial position.
- Brew time and a brief taste note.
Use the first cup to choose your next adjustment. The goal is a useful baseline you can refine, rather than a supposedly perfect setting that works for every bag.
How do you dial in espresso and filter coffee?
Dial in by changing grind size while keeping the rest of the recipe steady. Changing the dose, water amount and grind together makes it hard to identify what helped.
For espresso, use a dose suited to your basket and keep your target drink weight consistent. If the shot rushes through and tastes sharp or thin, try a small move finer.
If flow is very slow or stalls, a small move coarser is a sensible first adjustment. Uneven puck preparation can also cause poor flow, so distribute and tamp consistently before blaming the grind.
Taste matters more than reaching one fixed shot time. Time is a useful note, but the same time won't suit every coffee and recipe.
For pour-over or drip, start in the filter range and keep the coffee-to-water ratio steady. A slow, harsh brew can suggest moving coarser; a fast, weak or sour brew can suggest moving finer.
Those are starting clues, not automatic diagnoses. Water temperature, pouring and filter choice also affect the result, so change one thing at a time.
For French press and cold brew, begin with a coarser setting and a repeatable steeping recipe. If the drink is weak, check the coffee-to-water ratio and steep time before making a large grind change.
When switching methods, return to your saved position and expect a small correction. Fresh beans or a different roast can make yesterday's successful setting less suitable today.
What do the catch cups and retention features help with?
The catch cups help with collecting grounds and transferring an espresso dose, while the retention design aims to reduce carryover. These features matter most when you weigh individual doses or switch coffees.
There are 2 magnetic cups: one for coarser grounds and an espresso cup compatible with 54 mm and 58 mm portafilters. Check your portafilter size before counting on that transfer fit.
For espresso, transfer grounds carefully and check that the basket is evenly filled before tamping. A cup can simplify the transfer, but it doesn't distribute the coffee throughout the basket for you.
Weigh the grounds occasionally as well as the beans going in. That helps you spot a dose difference before changing the grind to solve a brewing problem caused by too little coffee.
Fellow says its anti-static technology reduces buildup and scattered grounds. Keep the catch area clean and empty the cup carefully, since static control doesn't replace routine care.

How easy is the Opus 2 to clean?
The Opus 2 offers tool-free burr access, which makes reaching the grinding chamber simpler. Fellow backs it with a 2-year standard warranty.
Unplug the grinder before removing parts. Follow the manual's removal and reassembly steps, and use a dry brush for accessible loose grounds where instructed.
Keep water away from the motor and grinding chamber. Wash removable parts only where Fellow permits it, and let any washed parts dry fully before reassembly.
Set your cleaning interval around use and the manual's guidance. More frequent grinding and visible buildup are reasons to check the chamber sooner.
Don't change calibration as a routine response to one disappointing cup. First check the recipe, burr seating and any accumulated grounds, then follow Fellow's calibration directions if needed.
Our guide to cleaning a burr coffee grinder covers a careful care routine.
Which alternative suits your daily coffee?
Choose the OXO for a repeated timed routine, the Encore for simple filter brewing, or the Encore ESP for stepped espresso adjustment. The Opus 2 remains the choice here for continuous control.
| Grinder | Main reason to choose it | Who should skip it |
|---|---|---|
| Fellow Opus 2 | Small continuous adjustments across brew methods | Brewers who want fixed reference positions |
| OXO Brew Conical Burr Grinder | A remembered timer setting for repeat brewing | Buyers seeking adjustment between fixed positions |
| Baratza Encore | Simple controls for learning filter recipes | Buyers focused on fine espresso adjustment |
| Baratza Encore ESP | Separate stepped ranges for espresso and filter | Brewers who specifically want a continuous dial |
OXO Brew: for a repeat morning routine
Choose the OXO if you usually brew the same coffee in the same amount. Its one-touch timer remembers the last setting, and its hopper holds up to 12 oz of beans.
It has 15 settings plus 43 micro-adjustments. Those defined positions suit a household that wants to write down a setting and return to it easily.
Skip it if continuous espresso adjustment is your main reason for shopping. Also remember that a timer controls grinding duration, so check the ground dose when you change beans or grind size.
Baratza Encore: for filter coffee beginners
Choose the Encore if you want to learn drip, pour-over or French press with straightforward controls. It has 40 settings, a front pulse button and an on/off switch.
Those controls suit someone who wants to see and stop the grind directly. Skip it if you want automatic shutoff or a dedicated fine-adjustment espresso range.

Baratza Encore ESP: for espresso with numbered steps
Choose the Encore ESP if espresso matters but you prefer a defined position for each adjustment. Settings 1–20 provide espresso micro-steps, while 21–40 cover filter brewing.
Its quick-release burr helps with access for cleaning. Skip it if you specifically want to settle between fixed positions, which is the Opus 2's main adjustment advantage.

Which mistakes should you avoid with the Opus 2?
Avoid large dial changes and changing several recipe variables together. Both make it harder to learn what the coffee needs.
Don't copy another brewer's setting as a final answer. Use it only as a starting point, then adjust for your beans, basket or filter, dose and water amount.
Don't assume a larger burr diameter alone guarantees better coffee than another grinder. Adjustment style, dose control, care and your ability to repeat a recipe all affect the buying decision.
Automatic shutoff means you don't have to stop the Opus 2 manually, but it doesn't measure your recipe for you. Decide how much coffee you need before grinding.
Finally, save separate notes for each brew method. One espresso note and one filter note are more useful than trying to remember the dial position while changing beans and brewers.
Should you choose the Fellow Opus 2?
Choose the Fellow Opus 2 if you'll use its small espresso adjustments and regularly brew filter coffee too. Be ready to weigh doses, record positions and refine the first brew after switching methods.
Choose the OXO for a repeated timed routine, the Encore for simple filter brewing, or the Encore ESP for espresso with numbered steps. Those are clearer reasons to buy than choosing by burr size alone.
Before ordering, settle on the brew method you'll use most often and check your portafilter fit and counter clearance. Then compare the Baratza Encore with the Fellow Opus or use the home burr grinder guide to resolve the remaining choices.
