Once you stick your head down the coffee rabbit hole, it can be nearly impossible to satisfy that hunger for greater understanding and greater skill.

At first, coffee is a black mystery juice. Then it becomes a liquid with some variation between origins.

Before long, you’re tasting specific acids and adjusting the grind in such small increments that you cannot see the difference – but you can taste it.

The rabbit hole goes deep.

There are hundreds, if not thousands, of internet resources for coffee (including Coffee Brew Guides), but the following have stuck out to me in significant ways, and have pushed me to new levels of coffee understanding and appreciation.
