What Are Tannins?
The most general and useful definition of tannins is any molecule that binds with proteins. You might think that’s not very helpful since it is an extremely broad definition, but it turns out that defining tannins more rigorously than that is actually quite difficult. Binding to proteins can happen in many different ways, meaning there isn’t a specific chemical structure to tannins like there is for other families of molecules.

What is Sean's obsession with coffee?
Sean’s obsession with coffee started when he received his first French press as a gift almost ten years ago. Since then, his love of coffee – and the number of coffee gadgets he owns – has grown considerably. A scientist by training, there is no stone he has left unturned in the never-ending quest for the perfect cup of coffee. He has spent many hours tuning his pour-over technique, thinking about how to best compare grind quality, and worrying about whether the Nicaraguan or Kenyan beans will make the best cold brew.These days he favors the Hario V60, and starts each day by hand grinding his coffee before enjoying a cup prepared with care and attention to detail.

What causes acidity in coffee?
Several factors seem to influence the acidity in a cup of coffee, including how long and at what temperatures the beans have been roasted, what kind of roaster was used and the method of brewing. The lighter the roast, the higher the concentration of acids tends to be; the darker the roast, the lower the acid concentration. Coffee grown at higher altitudes and in volcanic, mineral-rich soil typically has a higher acid content. Washed coffee has a higher perceived acidity than dry roasted coffee.

Next to the chlorogenic acids, aliphatic exist in the highest proportions in roasted coffee.
