  • Ideal tds and coffee to water brew ratio???

    Hey Everyone

    Can anyone tell me what the ideal TDS strength and coffee to water brew ratio is? I can find an official number for for the Specialty Coffee Association of Europe for a 1.2% to 1.45% TDS and a 6.67% brew ratio....but is this the same that is most commonly used in Australia for drip coffee? Or is it higher or lower?

    Cheers

    G'day,

    Sorry to answer a question with a question, but why do you need to know?

      Exactly! Who really gives a rat's ass? If it's good.. it's good... screw the numbers!!!

      Sheesh

        Yep agreed Vinitasse,

        I'm way too busy drinking mine to spend 10 minutes experimenting with it.

        Buy a brazen snle24. You can trade the scientific instruments on one. You won't need 'em.

          To be fair, the OP might have a valid reason for wanting to know. But if it's just for personal beverage brewing I echo the above comments.

            I would rather calculate the extraction yield (yield % = Brewed Coffee[g] x TDS[%] /Coffee Grounds[g]) and see if it's between 18-22% that is the ideal extraction yield interval according to SCAA.

              There is no one ideal TDS or brew ratio, it varies depending on the bean type or blend, roast depth, extraction method and personal taste. There is always a trade off between strength and yield. The numbers you have quoted will give you a starting point, try varying the numbers either side and see where it sits on your personal flavour profile.

                I read some of this stuff with a sense of dismay! we're talking about brewing coffee, if it too strong use less, too weak add a bit.

                Wouldn't be surprised if some clown calls for govt legislation calling for minimum strength standards for brewed coffee served in retail outlets, then they could set up a govt team of inspectors (gestapo) to carry out raids and impose fines for failure to comply with said legislation.

                  Hehe, this ^ goes to show how much trust the nanny government has lost lately. Back on topic, the TDS/yield measurements are useful in certain situations, for example when you're troubleshooting extraction issues or roast issue .. or if you're a coffee geek through and through. Other than that just trust your taste buds.

                    Hey Everyone,

                    Thanks for the responses so far. Normally I wouldn't care to put an exact number on this sort of thing, but this is for a special project comparing drip style coffee from around the world.

                    To simplify: what is the ratio of coffee to water people typically use? So basically, how many grams (or any other unit of measurement) of ground coffee are you combining with some amount of water...e.g. 100 grams of ground coffee combined with 1900 ml of water. I know this will always range but any example of recipe ratios would be great to hear!

                    Many thanks
