"Most of the roasted coffee bean, about two thirds of the bean's mass, is insoluble cellulose. The other third is dissolvable in water. Of that soluble third, most of it is the good stuff, particularly various organic acids and sugars. The rest are longer-chain molecules that we associate with astringent and bitter tastes. Where we find the happy balance is at the 19-20% point, that is, if you extract the first 19-20% of the mass of the coffee, we tend to find the best flavor balance. More than that and you'll find those astringent and bitter flavors start to dominate. Less than that and you'll find the resulting flavors thin and unbalanced, and with lighter roasted coffees, unusually sour. Timing really is what makes or breaks your coffee brew."
"A French press is often treated like Jason Segal's character in Forgetting Sarah Marshall. He's actually the one you want, but people tend to flock blindly to the flashy, temperamental types like coffee-siphon-somethings or Russell Brands. The French press is definitely a potential coffee happily-ever-after, but as with all things coffee, it ain't rocket science… but it is science! Let's delve a little deeper into how the French press works, and how you can make the best cup of coffee using this tool."
