Who would use a TDS coffee meter and why?
Coffee is one of the world’s most popular drinks. Consumers ready to drink cold brew coffee or coffee concentrate are becoming more sophisticated about its taste. And measuring total dissolved solids TDS allows you to know the coffee extracted rate and the coffee concentration. Thus, the coffee industry may install TDS coffee meters in their workplaces.
Besides, roasters use TDS coffee meters to test the beans to check if the roast is developing evenly. Professional coffee baristas also need a handheld refractometer to measure the consistency of the extraction. And drinking coffee lovers may use this tool to get the best home-brewed coffee. Shop owners of specialty coffees require the TDS meters to scientifically control their coffee quality. And machine manufacturers may use it to check the constancy of their coffee machines.
Why is the coffee refractometer useful?
Measuring TDS is of great help for them to understand the correct roasting time, coffee extracted time, and other factors for a golden cup of coffee. If you are a roaster, a barista or you own a shop for specialty coffees, a coffee densitometer refractometer is definitely worth a try. Even coffee professionals cannot only depend on their senses. So, a pocket coffee refractometer is necessary. To determine the coffee quality, some scientific data will help build a standard. If you want to make an expresso taste, you can dial in your coffee.
The coffee flavor depends a lot on the amounts of coffee solids dissolved in the ground coffee. If too little is dissolved, the coffee may be acidic, salty, or under-extracted. If too much, the coffee may be bitter with a charcoal taste. The measured TDS can help you dial in your coffee if it tastes bad. Both the under-extracted coffee and over-extracted coffee are difficult to distinguish by your taste alone. If you know the TDS (how strong your coffee is) in the coffee samples, you can use it to calculate the extraction rate. Then you can understand scientifically why your coffee tastes bad or good.
