On average, anyone can tell a good cup of coffee and a bad cup of coffee apart. But not everyone can tell a perfect cup of coffee from an average cup of coffee.

Distinguishing so, and identifying the quality of coffee, requires the perfect mix of three special ingredients. And these are:

And of course, chemical X – An ingredient that we don’t name officially but one that happens to be a weapon of most coffee professionals behind the scenes.

Any guesses as of yet?

(Well, yes, we know, the title says it all. But let us not ruin our script.)

So, yes, coming back to the chemical X, the special ingredient, it’s none other than a refractometer!

Fundamentally, a refractometer refers to an accurate instrument that measures the concentrations of aqueous solutions.  You only need to provide it with only a few drops of coffee, and it will let you know the exact chemistry of your blend.

Things to Consider

Before you make your final refractometer purchase, make sure you consider the following few aspects. With these, you will be able to determine whether or not a refractometer is a right pick for you.


Without a doubt, your primary concern is to establish the perfect balance between water and coffee solutes in your cup of coffee. You want to ensure the exact and accurate practical implementation of the recipe you follow. Isn’t it?

Well then, performance is the first and utmost important aspect to consider. Read the description and reviews of your preferred coffee refractometer and determine what degree of accuracy does it promise. Do users complain about the calibration? Or does the company itself admit negligible plus-minus differences in readings?

Know that you need to avoid all such refractometers. Why compromise on the basic function when you can get refractometers that provide accurate and exact readings?

Similarly, check out the temperature sensitivity. The standard temperature to evaluate concentration is plus minus 20 degrees. However, the figure can vary as per the specifics of a refractometer. So, generally, just look for one with precise temperature sensitivity.


When buying a coffee refractometer, consider the materials used to construct it. Opt for the ones built with premium quality materials so that they last longer and feel sturdy in hand.

Also, it’s better to choose models that can withstand extreme temperature changes. That’s because refractometers often have exposure to too cold or too hot beverages.

Constant exposure to high temperatures can lead to the development of cracks and the early expiry of the device. For that very reason, look up the durability that the manufacturing brand promises before making the final purchase. If possible, opt for the one that comes with a guarantee or warranty.


Another essential aspect is the ease of use that a refractometer offers. You surely don’t want to get yourself a refractometer with confusing controls and loads of maintenance demands that keep you occupied unnecessarily.

And so, the first thing you need to look into is the design. Check out its power and control buttons and determine if they are easy to read and understand.

Some refractometers, such as the AMTAST refractometer, have controls that involve waiting for 2 seconds for a certain thing to happen. Consider this and determine if you will easily get the hang of such operations or not.

Similarly, some require cleaning after every use. Some require the use of particular materials and chemicals for this cleaning. Again, it depends on you how much time you can invest in the mere maintenance of a device.

About the portability, all of the refractometers listed here are pocket refractometers. Their compact built makes it easy to carry around anywhere and everywhere. Hence, we suggest you opt for small-sized models as they add to convenience substantially.


Depending on your needs, set up a budget for yourself. Ask yourself how much do you ought to spend on a refractometer?

Do you use it too often or occasionally? Or do you need the refractometer for a one-time use?

In case you use it frequently, we will suggest you spend as much as need be, given that you can afford it. For an idea, the PAL COFFEE refractometer is an ideal pick for expert coffee professionals who have intensive usage of this device. But for beginners and occasional users, spending as little like that of Milwaukee will work fine too.
