Darker roasts tend to be stronger with less acidity whereas medium dark-roasted beans retain the distinct flavors of their respective regions or varietals. Both dark and medium roasting processes remove different flavors from beans but people like them better because they taste richer and stronger respectively.
Here it is: if measured by weight, caffeine content is virtually equal in light roast and dark roast coffee. But, if measured by scoop, light roast coffee will have oh-so-slightly more caffeine, since the beans are denser than a darker roast. Because they've been roasted longer, dark roasts have less mass.
If you prefer a more acidic, more subtle coffee that retains the character of the coffee beans, you're better off going with medium roast. If you prefer a less acidic, bolder coffee with the deep, rich taste often associated with traditional coffee, dark roast is your best option.
Dark roasts, with their bolder, gustier taste are typically seen as carrying a more substantial caffeine punch than light roasts. However, the stronger-tasting brews aren't actually an indicator of their caffeine content. Light roast coffee has approximately the same caffeine content as dark roast coffee per bean.
Light roasts tend to have more delicate yet complex flavor profiles than dark roasts. Dark roasts tend to have deep but simple flavors due to some of the initial flavors of the beans being lost or changed during the roasting process. Dark roast is sometimes described as tasting more bitter than light roast.
– Medium roast coffee beans are roasted for shorter periods of time and have a moister bean which makes them sweeter and than dark roasted coffees. They also have slightly less caffeine content.
As beans roast darker, both the caffeine content and origin flavors roast out. Darker roasts are slightly less acidic and have the least caffeine. Dark roasts get their bold, smoky flavor from oil that surfaces on the bean. Light and Medium roasts have little to no oil on the surface of the bean.
Light roast coffee
Light roast coffees are less bitter, more sweet, and often tea-like. They also often have the highest acidity. This isn't necessarily a bad thing as acid carries flavor. The presence of acid in coffee is often described as bright.
Black Label Brewed Coffee is believed to have the most caffeine per ounce at 129.6 mg. And when it comes to brand name caffeine, Coffee Bean & Tea Leaf's regular coffee packs the most caffeine per ounce at 20.8 mg. That's more than twice the amount of caffeine offered in McDonald's coffee (9.1 mg per fluid ounce).
PRO: Dark roast still contains chlorogenic acid lactones and melanoidins, which have antioxidant properties. CON: All research indicates that total free chlorogenic acid content decreases as the coffee is roasted to a darker level. This in turn impacts antioxidant activity of those particular polyphenols.
Medium-Dark roasts will develop in body. Body is used to describe the physical properties of the beverage and is associated with sensations of fulness, roundness, richness and denseness. Italian baristas insist that medium or medium dark roasts are perfect for making espresso.
The darker the roast, the more bitter the coffee. Think of baking chocolate chip cookies at home. If you end up burning your cookies, they'll taste more like coal than chocolate chips. Same with coffee.
Lighter roasts are often made from higher quality beans that are more expensive, which can drive up the cost of the coffee. On the other hand, darker roasts can be made from lower-quality beans that are more readily available, which can make them less expensive.
Dark Roasts - a study published in 2010 found that dark roast coffee is easier on the stomach than light roasts because it produces an ingredient that prevents hydrochloric acid from building up in the stomach. Cold Brew - brewing coffee using the cold brew method has been shown to increase the pH level of coffee.
Espresso packs a wallop when it comes to strength. Its concentrated brew has heaps of flavor and caffeine. The strongest coffee beans will taste even stronger. Even if you dilute espresso, it still tastes stronger than other brews at equal ratios.
Dark roast coffees tend to be less acidic because they contain fewer compounds that cause stomach cells to produce acid.
Which coffee type has the weakest taste? A latte is generally considered the least intense coffee. Made with freshly brewed espresso, the taste is then made less intense because of the volume of milk added, which makes it sweeter tasting and with a more mellow taste.
Light roast coffee beans are light brown in color and are a preferred roast for more mild-bodied coffees. Light roast coffee should not have any oil on the surface of the coffee beans. If you prefer light, fragrant, floral or fruity coffee notes - you'll enjoy a light roast coffee.
Let's dispel the most common myth right off the bat: A dark-roasted bean contains more caffeine than a light-roasted bean due to its stronger flavor. Not true. Actually, the caffeine content in both is virtually the same.
If your coffee is bitter-tasting, it means you dissolved more organic compounds and flavors than desired. As we now know, this is called over extraction. So, to remedy over extraction and brew a more balanced cup free of bitter notes, grind coarser for larger coffee particles.
You may get some coffee snobs shaking their head when you tell them you prefer the chocolatey notes of a darker roast. They'll tell you to always get a light roast. But just 10 years ago these coffee snobs would have been the ones singing praises about dark roast coffee!
