the roast affect flavor?
Typically, the lighter the roast, the more
local nuance in the taste... there will be more
fruit or floral elements, and a smoother experience.
As the roast darkens, acidity and local features diminishes and bitterness increases.
Many people like dark, bitter coffee, but there will be less variation between dark coffees from different origins, as long as high quality is maintained.
Full City, which is between medium and
dark roasts, has elements of dark
bitterness while retaining some acidity
and local identity.
