The size of your coffee grounds significantly affects the taste of your coffee. The finer the grind, the more flavor is extracted, and the coarser the grind, the less flavor is extracted.

Different coffee brewing systems require different types of coffee grinds. If your coffee is too sour or watery, you'll need to grind your beans finer. If it's bitter or extremely acidic, you'll need to grind your beans coarser.

A coarse grind is best for a French Press. This allows the water to move quickly between the pieces, extracting only some of the flavor.

A fine grind is ideal for espresso machines because it packs together well. This allows the water to pass through the grounds more slowly, extracting more flavor.

Using a fine grind in a longer brewing process, such as a French press, will result in over-extraction, producing a bitter brew. If your coffee tastes bitter, your coffee grinder may be too fine. It is possible to improve your brew by grinding it coarser.

The best grind size for coffee depends on the brewing method. For espresso, a fine grind size is best. For filter coffee, a medium to coarse grind size is recommended. For French press coffee, a coarse grind size is best.

Different brewing methods produce different flavors and caffeine levels. For example, espresso machines use pressure to quickly extract a rich, intense flavor, while a French press allows for a longer extraction time, resulting in a different flavor profile.

Drip coffee is brewed through a filter containing the ground, coarse coffee beans as boiling water is “dripped” on top. The filter leaves behind the ground coffee beans as liquid passes through and into a decanter or coffee pot that is then used for serving.

French pressed coffee is intended to be consumed immediately after brewing. A french press features a cylindrical glass carafe with a mesh filter inside which separates the ground coffee from the hot water. When it’s time to pour and serve, a lever is pushed down which strains and separates the coffee grounds from the brewed coffee.

Espresso machines use pressure to push hot water through a chamber/puck of finely ground coffee beans, through a filter, resulting in what we call a shot of espresso.

The AeroPress is a device for brewing coffee. Coffee is steeped for 10–50 seconds (depending on grind and preferred strength) and then forced through a filter by pressing the plunger through the tube.

Make sure that your tools — from bean grinders and filters to coffee makers— are thoroughly cleaned after each use. Rinse with clear, hot water (or wipe down thoroughly), and dry with an absorbent towel.

Fresh-roasted coffee is essential to a quality cup, so buy your coffee in small amounts (ideally every one to two weeks).

A general guideline is called the "Golden Ratio" - one to two tablespoons of ground coffee for every six ounces of water. This can be adjusted to suit individual taste preferences.

Use filtered or bottled water if your tap water is not good or has a strong odor or taste, such as chlorine. If you’re using tap water, let it run a few seconds before filling your coffee pot, and be sure to use cold water. Avoid distilled or softened water.

A Moka pot is a coffee maker that produces coffee by passing boiling water pressurized by steam through ground coffee. It is named after the Yemeni city of Mocha.

Pour-over coffee makers involve pouring water over and through the grounds to extract the coffee flavors into your cup or serving vessel. They are simple to use and offer a hands-on brewing experience.

Cold brew coffee is made by steeping coarsely ground coffee beans in room-temperature water for six to 12 hours. This produces a coffee concentrate you mix with cold water or milk.

A burr or mill grinder is best because the coffee is ground to a consistent size. A blade grinder is less preferable because some coffee will.
