Capresso Infinity Conical Burr Grinder: The Full Story
The Capresso Infinity Conical Burr Grinder is one of the most consistently recommended entry-level burr grinders on the market, and it's been that way for years. It sits at around $100-130 and offers 16 grind settings, a slow-speed conical burr mechanism, and a notably quiet operation compared to most grinders in its price range.
If you're trying to decide whether it's the right grinder for you, the short answer is: it's excellent for drip coffee, pour-over, and French press, decent for cold brew, and a compromise for espresso. I'll walk through everything, including how it performs across brew methods, what the "Infinity" actually refers to, and how it stacks up against the Baratza Encore and similar machines.
What Makes This Grinder Different
The "Infinity" in the name refers to the infinite number of micro-adjustment positions between Capresso's 16 labeled grind settings. Most grinders with discrete settings lock at specific click points. The Capresso Infinity lets you stop the dial anywhere between settings, giving you finer control than you'd expect from a machine in this price range.
Slow-Speed Grinding Mechanism
Capresso built the Infinity with a 450 RPM gear reduction motor. Most budget grinders run at 10,000-20,000 RPM directly, which generates significant friction heat. The Capresso's slow speed generates much less heat during grinding, which preserves the volatile compounds in coffee that create aroma and flavor.
The practical effect: your beans smell noticeably better as they're being ground, and cup quality is slightly better when you compare it to a faster motor running at the same price point. This is also why the Infinity is comparatively quiet. The motor isn't spinning at screaming RPM.
Conical vs. Flat Burrs
Conical burr grinders like the Infinity use cone-shaped burrs where beans travel in a spiral path, staying in contact longer for a thorough grind. Flat burrs use two parallel discs. Both designs can produce excellent results; the difference matters more at higher price points. At the $100-130 range, the conical design in the Infinity contributes to consistent grounds without much retention (grounds left in the burrs after grinding).
Grind Range and Settings
The Infinity has four setting zones, each with sub-settings:
| Zone | Settings | Best For |
|---|---|---|
| Extra Fine | 1-4 | Turkish coffee |
| Fine | 5-8 | Espresso (with caveats) |
| Medium | 9-12 | Drip, pour-over, Moka pot |
| Coarse | 13-16 | French press, cold brew |
The sweet spot for most people is the medium range (9-12). Settings 10-12 work well for auto-drip coffee makers, and setting 8-9 handles most pour-over methods like Chemex or V60.
Does It Work for Espresso?
This is the most debated question about the Infinity. The fine settings (5-8) do reach espresso-appropriate particle sizes, but consistency at that fine end is lower than dedicated espresso grinders or the Baratza Virtuoso+. If you pull shots on an entry-level espresso machine (Delonghi Stilosa, Gaggia Classic), the Infinity can produce acceptable espresso after careful dial-in.
If you have a semi-automatic or prosumer machine (Breville Barista Express, Rancilio Silvia), you'll likely frustrate yourself trying to dial in espresso on the Infinity. The precision just isn't there at the fine end.

Build Quality and What You Actually Get
The Infinity is built with a combination of stainless steel and quality plastic. The housing feels solid; it's not a cheap-feeling machine. The hopper holds about 8.8 oz (250g) of beans, which is enough for about 15-20 cups before you need to refill. The grounds container sits below and holds a similar amount.
What's Included
- Stainless steel or black housing (both available)
- 16-setting adjustment ring
- 8.8 oz bean hopper with lid
- Grounds container with window
- Cleaning brush
Noise Level
This is a genuine differentiator. The Infinity runs at roughly 65-70 dB, compared to 80-90 dB for many budget grinders. In a quiet kitchen at 6 a.m., that difference is significant. If you have a sleeping partner or baby in the next room, the Infinity is one of the better choices at this price.
Capresso Infinity vs. Baratza Encore
These two grinders come up in every comparison at the $100-150 price range, so I'll be direct about the differences.
Baratza Encore Advantages
- 40 grind settings vs. 16 labeled settings on the Infinity
- Better espresso grind consistency
- Baratza's service program: you can send the grinder back for repairs, and parts are sold directly on their website
- Slightly better build quality on the motor and burr housing
Capresso Infinity Advantages
- Quieter operation (meaningfully so)
- Lower price (usually $20-40 cheaper)
- Micro-adjustment between settings gives more flexibility
- Slower RPM means less heat, which some coffee enthusiasts prefer
The Baratza Encore is the better grinder overall, especially for espresso and for users who want a larger setting range. But the Capresso Infinity's quieter operation and lower price make it the smarter buy for people whose priority is drip and pour-over coffee at reasonable cost.
The Best Burr Grinder roundup compares these two alongside the Oxo Brew, Cuisinart DBM-8, and others if you want a side-by-side look.
Common Issues and How to Handle Them
Grounds Retention
The Infinity retains about 1-2 grams of grounds in the burr chamber between grinds. This means if you haven't used it in a few days, the first batch out will include slightly stale grounds from the last session.
Solution: run a few grams of fresh beans through first and discard, or use a grounds knocker to clear the chamber before brewing.
Static Clinging
The grounds container builds up static charge with certain bean types, causing grounds to cling to the container walls. To reduce this, try the Ross Droplet Technique: add one or two drops of water to your beans in the hopper before grinding. The moisture reduces static significantly.
Grind Calibration Drift
Some users report that the dial can shift slightly during grinding if not fully tightened. Before using, press the adjustment ring firmly into position. If settings drift, Capresso includes instructions in the manual for recalibrating the zero point.
Cleaning Schedule
Aim to clean the Infinity every 2-3 weeks with daily use. Remove the hopper, brush the burrs with the included brush, and wipe down the grounds container. Capresso recommends their own Capresso cleaning tablets monthly. Urnex Grindz tablets work as well and are widely available.
Who This Grinder Is Actually For
Best fit: Someone upgrading from a blade grinder or cheap electric burr grinder who makes drip coffee or pour-over daily and wants a noticeably quieter machine.
Good fit: Light espresso users who pull occasional shots on an entry-level machine and don't need the precision for consistent espresso extraction.
Not the best fit: Serious espresso enthusiasts, households grinding more than 60g at a time (the hopper isn't large enough for high-volume use), or people who want more than 16 discrete settings.
FAQ
How many cups can the Capresso Infinity grind before the hopper needs refilling?
The 8.8 oz hopper holds roughly 250 grams of beans. A standard 12-cup drip batch uses about 60-70 grams, so you get roughly 3-4 full batches before refilling. For single-cup use, that's 12-14 cups per hopper fill.
Does the Capresso Infinity work for pour-over coffee?
Excellently. Pour-over methods like the Chemex, Hario V60, and Kalita Wave all perform well with Infinity grinds at settings 9-11. The consistency at medium grind range is strong for this price point, and you can fine-tune between settings for different flow rates.
Can you grind dark roast beans in the Capresso Infinity?
Yes, but dark roasts are oilier, which means more residue on the burrs and faster buildup of rancid oils. If you drink primarily dark roast, clean the grinder every 1-2 weeks instead of monthly.
What's the warranty on the Capresso Infinity?
Capresso offers a 1-year limited warranty. That's shorter than Baratza's warranty program and doesn't include the same level of repair support. For a $100-130 grinder, it's reasonable but not exceptional. Keep your receipt.
The Bottom Line
The Capresso Infinity Conical Burr Grinder earns its reputation as one of the best entry-level burr grinders for drip and pour-over coffee. The slow-speed motor, 16-setting range with micro-adjustment, and genuinely quiet operation are all real advantages at the $100-130 price point.
If espresso is your primary focus and you want more precision, stretch the budget to the Baratza Virtuoso+ at $250. For everything else, the Infinity is a smart buy that will noticeably improve your daily cup quality over any blade grinder or cheap burr model.
