Effective refractometer; fun toy for espresso tuning.

I primarily bought this refractometer for espresso tuning. While its more common (and useful) at-home use for brewing beer, I got it to try out measuring TDS within espresso shots.

With the included app, I found that it was pretty usable - more so than hard-to-use and hard-to-decode professional calibrated tools. And its slim form factor makes it easy to store or even take on-the-go.

Running a few samples, I found that it had some amount of variance in between samples of the same liquid. This suggests some amount of error on the measurement. However, when I tested it against some calibrated equipment at a local brewery, we saw that it measured with only a few percentage points of error - quite impressive for a little pocket tool.

Ultimately though, this product falls into a tricky range. The mid-range version has excess range for alcohol use, and too little range for honey, etc use. That makes it good for coffee ideally, but measuring coffee with a refractometer is not a super useful indicator, even for professional breweries. It's always a good tool to have to test for consistency and to feel like a scientist, but I haven't noticed any improvement in taste or quality by using this to dial in my pours.

Make a better cup of coffee

I got this thinking I would be able to zero in on a better cup of espresso. I LOVE my coffee so why not try to make it the best coffee ever? So I played with the refractometer and figured out that to make better coffee, I needed better coffee-making equipment. While I get better equipment I have been measuring liquids all over my home. This definitely an instrument for the true coffee, wine, or beer make who is also somewhat of a geek.

Small, Simple, Fast, Accurate.

I was planning on doing some home brew from a sugar beet crop. That's off in the future yet but had a chance to get this a head of time for it. So I have not had experience in actual intended use, but I can say from my initial look of all included and performance this will do the job just fine. Everything you need is in the box except of course the phone App for download which will give you more data than just on the units digital display. The simplicity and accuracy of this unit is what drew me to it and the simple set up tests I did prove that to be the case. This is the type item you will have for a lifetime and for many type uses.

This particular refractometer is incredibly easy to use and to read

I recently started brewing beer at home and decided to purchase a refractometer to measure the total sugar content of the wort. This particular refractometer is incredibly easy to use and to read. It's both an excellent value and an excellent and indispensable tool. Highly recommended for frequent or small-batch homebrewers.
