A bitter, harsh cup in particular can be genuinely disappointing. The good news is that once you understand what's causing it, it's usually easy to fix.     Start With the Root Cause Before you can fix bitter coffee, you need to understand why it's happening. In most cases, bitterness comes down to over-extraction — pulling more out of the coffee than you actually want. This usually happens when the brew time runs too long, the water is too hot, or the grind is too fine. Let's break down each cause and how to fix it.     7 Ways to Reduce Bitterness 1. Grind Size A finer grind breaks the coffee into smaller particles, which increases the total surface area in contact with water. The finer the grind, the more of that surface gets exposed — and...

It's frustrating, and it usually comes down to one thing: not fully understanding what's actually happening during extraction. To brew consistently great coffee, you need to understand the five core variables at play: roast level, grind size, brew time, coffee-to-water ratio, and water temperature. Know Your Taste First Coffee can taste dramatically different depending on how it's brewed, even from the exact same beans. And what counts as "delicious" really depends on personal preference. At the simplest level, taste preferences usually come down to a few basic axes: acidity vs. bitterness, and strong vs. mild.   Some people love the bright acidity of a light roast; others prioritize a nutty, toasty flavor; and some prefer the deep bitterness of a dark roast. Preferred strength varies...

This post digs into one part of that world: extraction. We'll walk through the three main brewing methods — immersion, filter, and pressure brewing — along with the tools that go with each.   The Basics of Coffee Extraction Coffee extraction is the process of pulling flavor, aroma, and color out of ground coffee using water (or occasionally another solvent). How that extraction turns out depends on a handful of variables: the type of bean, the grind size, the brewing method, and the water temperature. The methods that shape all of this generally fall into three categories — immersion , filter , and pressure brewing.     Immersion Brewing How It Works Immersion brewing means steeping ground coffee directly in water, letting the soluble compounds di...
