There are a lot of misconceptions when it comes to coffee and roast levels. The aim of this post is to bring a little clarity to a couple of these misconceptions, and to help you find the right roast for you.
1) Dark Roast coffee has the most caffeine.
Caffeine is one of the naturally occurring chemicals in coffee that burn out during the roasting process, so typically the lighter the roast, the more caffeine it will have.
2) Light Roast coffee is weak.
This isn't necessarily false; bad light roast is weak in flavor, but good light roast is very lively with fruity notes accented by an appropriate acidity that compares to citrus fruit. Bad light roast comes from low quality beans that lack flavor until they reach dark roast, which is the point of the roasting process where you lose the flavor of the coffee's origin and it is replaced with a more uniform smoky/burnt flavor.
Typical Profiles of EQ Coffees:
Light Roast- lively, typically with notes of fruit, teas and/or florals. Most Caffeine.
Medium- rich sweetness where flavors of cocoa, vanilla and stone fruits begin to dominate the cup. Medium Caffeine.
Dark- dominating smoky flavor often with notes of cocoa. Least Caffeine.
