Ladies and gentlemen, there’s geekery and then there is geekery. Portafilter.net has just published a terrific set of equations for the MojoToGo set. Probably would’ve sounded really good in podcast form. (Sigh…)

Don’t skip this lesson:

Given extraction yield, mass of coffee, mass of water, and water absorption factor, calculate TDS:

TDS = mass of solubles ÷ mass of solution
mass of solubles = extraction yield × mass of coffee
mass of solution = mass of water + mass of solubles – absorbed water
absorbed water = mass of coffee × water absorption factor
Therefore, TDS = mass of coffee × extraction yield ÷ ((mass of water + (mass of coffee × extraction yield)) – (mass of coffee × water absorption factor))

Absolutely fascinating and perfect for making coffee brewing more accessible to consumers.

There’s more.
