density.coffee

If you don't know where your coffee is on the 150 point density spectrum from very lightly roasted to very dark, then you are just guessing : how long your coffee beans will continue to improve after roasting, how long will the beans take to stale, what ratio, dose, yield, temperature, pressure, and time to use. Most likely you will under extract making your coffee sour or over extract making your coffee bitter, missing the sweet spot altogether.
A quick and simple measurement of the density to determine the exact roast level, and use of the density.coffee tool,  will improve your coffee.
