The Capresso Infinity is enticingly cheap for a burr grinder, but unfortunately it failed to present any of the benefits of a burr model in our testing. In fact, it only fared slightly better in our all important grind consistency test than some of the much less expensive blade grinders. It also tends to spill a lot of grinds onto the counter, and isn't the easiest machine to use. We will say that it is a bit quieter than most of the other models in its price range, but we don't think that alone makes it a compelling option for those shopping on a budget.

Our Analysis and Test Results
The Capresso Infinity isn't a bad grinder, but in our opinion it fails to find a meaningful niche for itself in the current market. There are other inexpensive burr models that do a significantly better job, and there are much less expensive blade models that aren't too far off from the Infinity's performance.
The only thing we would say we really like about the Infinity is the fact that the noise it makes is a bit less offensive than the squeals of most of the other lower-priced burr grinders on the market. It registered just 83 decibels on our noise meter, making it one of the quieter models of the bunch. The pitch it emits is a bit lower than that of most comparable models as well, making the overall sound a bit less grating. The pitch does undulate a bit, which makes the noise a bit more noticeable, but it never verges into full-on annoying territory.
Apart from a relatively innocuous noise, we didn't encounter anything in our testing that really got us excited about the Infinity.
Our biggest qualm with the Infinity is its grind consistency. You would both hope and expect that a burr grinder would be a step up in terms of grind consistency when compared to any blade grinder. The Infinity is a step up from all the blade models we tested, but only by a small degree.
The biggest problem we found with this model's grind consistency is its propensity to create fine coffee dust (often referred to as fines). These fines expose more surface area to water and cause the water to move through the grinds more slowly, leading to over extraction. When we ran the Infinity's grinds through a series of sieve shakers we found a whopping 30% of those grinds to be fines, something we saw in no other burr grinder.
Apart from creating a lot of fines, the Infinity also tends to hang onto a lot of grinds in its chute. This often leads to multiple grams of coffee spilling out of said chute, creating a mess on your counter. After every use we ended up tapping the machine to release all of those pent up grinds so they wouldn't affect the tests we ran next.
Our final complaint is the lower burr of this machine is quite difficult to remove and clean. That problem is especially frustrating since so many grinds tend to get stuck in the machine.
While the Capresso Infinity is inexpensive, we don't think it presents a very good value within its price range. There are other, similarly priced burr grinders that outdid it in almost all of our tests, and you could spend much less on a blade grinder without sacrificing too much performance.
While there's nothing we absolutely hate about the Capresso Infinity, there's nothing we absolutely love either. No matter your needs or budget, we think you'll be able to find a grinder that better suits your situation.
