Difference between light and dark roasts
Harvesting and Processing:-
The berries are normally harvested through machines and also picked by hand. To get the beans out, the fruit of the berry needs to be removed and after that, the beans need to be processed. There are following two ways of processing beans:
· Dry processing: It is the oldest method of coffee processing. The dry-processed beans are placed in the sun and left to dry for around two weeks while being turned from time to time so they can dry evenly.
· Wet processing: It is a modern method of processing beans and it takes place soon after the harvest. This coffee harvesting process consists of washing and fermentation. During this process, the pulp that is left on the beans will become softer and the pulp is rinsed off. Today, this method of processing is used more frequently since it prevents damage to the beans.
Difference of Coffee Roasts:
Coffee roasting is a heating process that brings out the aroma and flavor locked inside a green coffee seed, which has a mild, grassy taste on its own, and turns the beans brown. The flavor profile of a bean's roast level will depend on the varietal and geographic location of that bean as well as the roasting method.
Color: Light brown
Oil on Surface: No
Flavor profile: Toasted grain with pronounced acidity
Amount of Caffeine per Scoop: High
Internal Temperature Of Beans At Roasting Peak: Approx. 400°F
Color: Dark Brown
Oil on Surface: Some
Flavor profile: whole body flavor Thick, with little taste of spice
Amount of Caffeine per Scoop: Low
Inner Heat Of Beans At Roasting Peak: Approx. 445°F
How the flavor differs:
Associated with dark roasts, light roasts tend to have more elegant but compound flavor profiles. However first flavors of the beans are lost or transformed during the roasting process, dark roasts tend to have deep but simple flavors
Light roast coffee also tends to have a thinner mouth feel than dark roast. The natural oils present in dark roast coffee beans increase the viscosity of the final product, which makes it feel thicker in your mouth.
Light roast coffee is often described as:
bright
crisp
acidic
fruity
Dark roast coffee is often described as:
bold
robust
smokey
chocolatey
Which one is healthiest?
· Both light and dark roast coffees contain antioxidants and polyphenols, light roasts might be higher in these nutrients, as dark roasts lose somewhat more plant chemicals during the roasting process.
· Light and dark roast coffees each have nutritional pros and cons. Light roasts may be higher in healthy antioxidants and polyphenols, but they might also contain higher amounts of a harmful chemical called acrylamide.
· Dark roast drinkers lose more bodyweight as compare to light roast drinkers.
· Light roast contains more chlorogenic acid, an antioxidant that lowers inflammation, per research from the National Coffee Association.
