Coffee Grinder Service & Repair

Grinder Service & RepairTwo important, often neglected, requirements for good espresso are a quality grinder and soft, good tasting water.  Let’s discuss the grinder.

The coffee making process consists of moving water through ground coffee, you should pay close attention to those two items. Regardless of how much money you spend on an espresso machine, using improperly ground coffee and/or bad tasting water will produce lousy tasting coffee.

A grinder’s sole function is to produce consistently sized grounds.  Without that consistently sized ground, your high dollar coffee machine will never make a great cup of coffee. There are numerous, quality commercial and home grinders that produce great coffee grounds. However, you won’t find a good, new, commercial grinder for $150 or a good, new, home grinder for $25.

Once you’ve adjusted your quality grinder to produce the grounds which best suit your coffee, don’t assume that setting will never change. You will find that  humidity effects your espresso shot time.  Higher humidity usually requires a little finer grind, while lower humidity may require a slightly coarser grind.

The grinder burrs are what actually cut the bean and they have a finite lifespan; as the burrs wear, you must adjust the grind setting to maintain the same grind. Depending upon several variables [cutting area (i.e. 58mm, 63mm, 71mm), shape (flat or conical), and the manufacturing material (steel or ceramic)], burrs will grind anywhere from 600 to 40,000 lbs of beans before requiring replacement.  Check the manufacturer’s literature to find your model’s burr rating.

Here are the manufacturers’ recommended burr ratings for some of the more popular commercial grinders:

Manufacturer Model Burr Size Flat (F) or Conical (C) Burr Life (in lbs of coffee)
Anfim Caimano 75mm  F 1,300
