There’s so much more to a great cup of coffee than the bean or how it was roasted. The age of the roast, grind size, brewing method, water temp, and coffee-to-water ratio can all create completely different flavors from the exact same bag of beans.

This article is to help you get the maximum flavor from your cup of coffee without too much work in the mornings and getting too nerdy. Once you dial things in, it’s pretty much a set and forget process.

For most people reading this, the beans have already been roasted to complement their region and flavor profile. The rest is up to you—how strong you want your coffee, how much caffeine you prefer, and how smooth you want each cup to taste (If the bean allows).

I personally use an AeroPress, a Chemex, and a Fellow Aiden. When I travel, I bring my AeroPress along to make my morning cup of Joe. At home, I enjoy the simplicity of the Fellow Aiden. The Chemex makes amazing coffee, but most mornings I prefer the Aiden’s automatic blooming and pour-over process.

To grind my coffee, I use the Fellow Opus 2 grinder. It produces an excellent grind, works quickly, and does an outstanding job for the money. There are better grinders out there, but I believe this one offers some of the best bang for your buck.

The reason I don’t currently offer my beans pre-ground is simple: coffee begins losing its vibrant aroma and flavor shortly after it is ground. Grinding exposes much more of the coffee to oxygen, allowing many of its aromatic compounds to disappear quickly. I may eventually offer a ground option, but if you’re chasing that perfect cup of Joe, I highly recommend grinding your beans immediately before brewing.

The Extraction Process

After coffee is roasted, the beans begin releasing carbon dioxide. This degassing process is especially active during the first several days after roasting, which is why coffee often benefits from a short 4-6 day resting period before brewing.

You might think the freshest possible roast will always produce the best cup—and freshness is certainly important. However, brewing beans too soon after roasting can make extraction more difficult. The excess carbon dioxide can interfere with the water’s ability to evenly reach the coffee, sometimes resulting in a sharper, more acidic, or puckering taste.

Grind size is another important part of the extraction process. It controls both the amount of surface area exposed to the water and how quickly the water moves through the coffee.

A coarse grind allows water to pass through more quickly, extracting fewer compounds and potentially producing a sour, acidic, or weak cup. A fine grind slows the water down and extracts more from the coffee, but going too fine can create a bitter, over-extracted flavor.

For this article, I’m focusing mainly on drip and pour-over brewing. Grinding for French press, espresso, cold brew, and other brewing methods is a topic for another day.

The Grind for Drip and Pour-Over

For drip or pour-over coffee, start with a medium grind—roughly the middle of your grinder’s range.

Keep in mind that grinder settings are not standardized. A setting of 6 on one grinder may produce a completely different result on another brand or model. Flat-burr and conical-burr grinders can also produce different results.

I use an Opus 2 conical-burr grinder and find that a setting around 4.3 works well for most of my coffees using 2oz of beans. I enjoy a little more extraction from my beans, partly because I use less coffee than the standard coffee-to-water ratio to keep my caffeine intake down. I like a smooth coffee without too much of a pucker taste (sour).

Coffee-to-Water Ratio for Drip and Pour-Over

A common starting ratio is 1:16—one gram of coffee for every 16 grams of water. For a standard mug made with 8 ounces of water, that works out to approximately 15 grams of coffee.

Personally, I find that ratio a little too strong. I drink around four cups of coffee throughout the day, so I prefer a more diluted ratio that doesn’t wind me up too much.

This is where trial and error comes in. There is no single “correct” ratio that works for everyone. Your ideal cup depends on your taste, brewing method, beans, and how much caffeine you want.

The Bloom

For fresh coffee, blooming helps greatly. This is where you wet your grounds with a small amount of hot water, then wait 30 – 45 seconds before the main pour. This helps release trapped carbon dioxide gas, giving a better extraction process. The good automatic coffee makers will have this feature built in.

Water Temps

Mix and Match Your Grind and Ratio

This is my favorite part of finding the right cup. Don’t be afraid to experiment with your grind setting and the amount of coffee you use. I recommend changing just one thing at a time and making small adjustments. That makes it easier to understand how each change affects the final cup.

Over time, you’ll begin recognizing the difference between coffee that is sour or under-extracted, coffee that is bitter or over-extracted, and coffee that tastes smooth and balanced.

There’s a whole world to explore in your cup every morning. People who think coffee is simply bitter have probably only experienced bad coffee.

Soon, you might find yourself sitting on a beach or standing on top of a mountain, treasuring every sip as you start your day. I’ve honestly lost sleep from the excitement of waiting for my next morning cup.
