I was wondering if all you could give me some suggestions about Pocket coffee densitometers. There are some in Amazon like: PAL-COFFEE (BX / TDS) From import JPN; but for me seems to be very expensive. Any suggestions?
Coffee preparation techniques besides espresso like pourover.
There's one in aliexpress for around 100€. It's their anniversary shopping frenzy time so I saw lowest for 91€ or so. You can use the search term "coffee refractometer". It's the one with yellow white color. I suppose you can also find it on Amazon or alike.
