How can a refractometer help me dial in coffee?
The key to brewing exceptional coffee lies in achieving the perfect balance of flavors. A refractometer enables you to precisely measure the TDS, allowing you to adjust various brewing parameters, such as grind size, water-to-coffee ratio, and extraction time. By accurately dialing in your coffee, you can extract optimal flavors, accentuate more desired flavors or mask less desirable flavors.
What is TDS?
Total Dissolved Solids (TDS) represents the concentration of soluble substances present in a liquid. In the context of coffee, TDS measurement reveals the amount of dissolved coffee solids, including minerals, oils, sugars, and acids. By understanding the TDS level and how much of the coffee you have extracted, you can fine-tune your brewing technique to achieve desired flavours, sweetness, and body in your cup.
It is important to keep in mind that TDS will only measure the total of all the dissolved solids in your coffee, this means that you can have 2 samples with the same TDS and have 2 completely different tasting coffees.
