The Four “M”s of Perfect Coffee, Part 2: Mill

(This is Part 2 of a 4-part series called “The Four ‘M’s of Perfect Coffee”, in which we’ll talk about the four elements of making great espresso-based drinks at home: Machine, Mill, Mix (blend), and Method.)

The Second “M”: Mill

Unlike shopping for an espresso machine, which can require quite a bit of research and forethought, it’s fortunately not difficult at all to shop for a proper mill or coffee grinder. There are a few key attributes to look for, but those questions are often answered right on the box. Here’s what you want in a good grinder:

1. Look for steel conical burrs. The “burr” is the piece of the mill that actually grinds the coffee beans. Sometimes this is done in cheaper mills via blades and not burrs which can be fine for infrequent grinding for automatic drip machines, but to get a proper espresso grind, blade mills are too inconsistent. Also, make sure the burrs are metal and not plastic, as plastic burrs warp and break easily with even light use.
2. Check the range of grind adjustments. The more settings, the better. Commercial espresso grinders can adjust the grind by 5 microns up or down. You don’t need a mill quite that granular, but grind has a very important effect on your espresso and you should get a mill that will allow you room to experiment to find the best grind for your particular machine. Three or four settings won’t cut it.
3. A reliable reputation is worth a lot. Even the best grinders can eventually break down, so look for a brand with a history of mechanical reliability and positive customer service. Bodum, Saeco, and Capresso are all good names to start with.

Got Any Recommendations?

To get you started, here are a few models to consider.

Bodum Antigua Electric Burr Grinder–This unit gets all the basics right at a reasonable price ($80-90), but has some minor durability issues, particularly in the nylon gear teeth. Customer service from Bodum is always good, but be prepared to baby this machine a little bit.

Capresso 560 Infinity Burr Grinder–Almost the complete opposite of the Antigua in the sense of being mechanically reliable, but with some minor flaws in form factor. Overall a solid unit at the same price point as the Antigua, with equally strong customer service, but a few people have found that some nonmechanical parts don’t always fit perfectly and may crack easily.

Baratza Maestro Plus Conical Burr Coffee Grinder–The stolid workhorse of the prosumer market, it’s hard to go wrong with the Baratza Maestro. It’s reliable on every level and won’t heat up your beans with repeated use. Expect to pay about $140-150.
