01. Roast Level
Perhaps unsurprisingly, the most important factor influencing taste was the roast level of the coffee beans. Before roasting, coffee beans are green with little or no taste. Roasting develops different aroma compounds, and the length of the roast affects these compounds and determines the flavor. Many people choose a medium roast, but it’s worth exploring both lighter and darker roasts to get a greater appreciation for different flavors, and learn which roast suits you.
Lighter Roast
Light brown in color with no oil on the surface of the beans, light roasted coffee is commonly more acidic with fruity, bright flavors. A light roast retains the unique origin flavors of the beans to a greater degree.
Medium Roast
A medium roast is brown in color and offers more body than light roasts. The coffee starts to approach the darker, caramel sweetness of a longer roast, and exhibits a more balanced flavor and aroma.
Dark Roast
A dark roast has low acidity, heavy body, and deeper, darker flavors. The origin flavor of the coffee is overtaken by the roasting flavors, with a taste that is bitter, smoky and earthy.
02. Filter shape
This factor might surprise you, but the shape of the basket has a greater impact on flavor than most other variables. By simply swapping out the filter basket, you can dramatically transform the flavor of the brew. The experts found that certain flavors are associated with different basket shapes, so you can choose a basket for brewing that matches your flavor preferences.
Flat bottom basket
Sweet, floral, dried fruit and chocolate flavors were emphasized with brewing in flat bottom baskets.
Semi-conical basket
Bright, berry, citrus and fuller-bodied brown roast notes were emphasized with brewing in semi-conical shaped baskets.
03. Brew Ratio
This is the ratio of ground coffee to water used to brew, and it makes sense that varying the ratios will affect the flavor of your coffee. Most baristas would use brew ratios of between 1:15 and 1:18, which means for every gram of ground coffee they are adding between 15 grams to 18 grams of water.
Less Coffee
The less coffee that is used, the increased perception of sweetness. The coffee will offer a more mellow and rounded taste with gentle acidity.
Recommended
The brew ratio you decide upon will be guided by your personal taste preferences, but a ratio of 1:18 will deliver a rich and balanced flavor.
More Coffee
With more coffee used in the brewing process, the coffee will be more concentrated, with a rich, crisp taste and greater acidity.
04. Grind
Grinding coffee beans increases the surface area of the coffee that comes into contact with the water, and how coarse or fine the grind is determines how quickly water can pass through it. In turn, this influences how your final brew tastes. Your personal taste preference will determine the ideal grind size.
Fine
A finer grind has the coffee packed closer together, so water takes longer to pass through, leading to greater extraction, more bitter flavors and a thicker body.
Coarse
A coarser grind allows water to flow through the coffee more quickly, with a shorter brew time and less extraction, creating floral and dried fruit flavor notes.
05. Brew Time
The length of time the coffee stays in contact with the water affects the level of extraction, which is the process of drawing the flavor compounds from roasted and ground coffee. These compounds are not all extracted at the same time. First up are the fruity and acidic notes, followed by sweetness and balance, and lastly bitterness. As a result, the brew time produces different coffee flavors.
Shorter
When the coffee is brewed for a shorter time, fruity, sweet, and spicy notes are emphasized, along with brightness which coffee tasters refer to as acidity.
Longer
Coffee brewed for a longer time will have a fuller-bodied and thicker taste as the compounds that create sweetness and acidity will be overwhelmed.
06. Temperature
During extraction, water draws the flavor from the coffee grounds. The temperature of the water is an essential part of the process because if the water is too hot you risk an over extraction, resulting in a bitter tasting coffee, and if the water is too cold, under extraction may occur leaving a weaker, sour-tasting coffee. As part of the research, we found within our temperature testing range of 188-200°F (87-93°C) there wasn’t a significant flavor difference, but coffee connoisseurs might appreciate the flavor subtleties.
