No matter how you brew your coffee; drip, espresso, press pot, or perc, your grinder has to do its job correctly or your cup will be doomed from the start. If you are still using one of the blade grinders you will probably not believe how important the grinder is until you start using a good grinder. Maybe "doomed" is an overstatement, but you just cannot make a great cup with a grind from the whirlybird. The problem is consistency. Look at the grind carefully, with strong light and under magnification. You will see a wide variance in the particle size, from tiny pieces to dust. The difference in particle size causes a difference in the extraction process, and results in over extraction of some of the coffee and under extraction of other. Also, you can't control the fineness of the grind with the blade. If you want a fine grind, you have to let it grind longer, which makes more coffee dust and, because of the speed of the blade, the coffee is overheated during the grind. Overheating changes the taste of the cup. Inconsistent particle size changes the taste. Precision and consistency are the keys to good coffee.
This Capresso Infinity grinder is a good grinder. It does its job so you can concentrate on the other aspects of brewing a great cup of coffee. It is easy to use, easy to clean, produces a consistent grind, and is priced right.
The model I tested is the 560. It has a black plastic body and retails for $89.95. It takes a 5"x7.5" footprint and stands 10.5" tall. There are 16 fineness settings, from very coarse for French press to very fine for espresso or Turkish. The commercial heavy steel burrs grind slowly and with precision to reduce heat build-up and static electricity. I examined several grind settings under magnification and saw almost perfect consistency in particle size. It's very easy to clean, just by taking off the clear plastic hopper and lifting out the moveable burrs. It comes with a scoop and a cleaning brush. I recommend cleaning after each grind, because there is a residue of about a teaspoon of coffee that should be removed. The shelf life of ground coffee is measured in minutes, so you don't want that residue in tomorrow's coffee.
The operation of this grinder is simple. Turn the top housing to line up a black dot with the desired fineness setting. Fill the hopper with a measured amount of roasted beans, turn the timer clockwise to start, and when the grinder stops, slide out the collection tray for the ground coffee. The timer's max is 10, which is about 60 seconds. The hopper holds about one cup, much more than I need for my 12 cup press pot. Warning, the top hopper is so clear I forgot to take off the lid and spilled beans all over the counter and floor. It's good that no one was watching this klutz in action.
The grinder is quieter than most, which is important for those who get up first in the morning and don't want to wake the house with grinder noises from the kitchen. (Do you wake up grouchy in the morning? No, I let my wife sleep late.)
Negatives:A design on the top lid to make it visible for klutzes. (I've added one to mine.)
Make the base more ergonomic to make it easier to hold when cleaning out the residue.
Make the dot on the upper housing larger.
Positives:Consistent particle size produces consistent extraction.
Easy to control fineness settings.
Easy to clean.
Good price at $89.95. There is a chrome (brushed or bright) version for $139.95.
Quiet operation.
I like this grinder and recommend it.
