Coffee roasting is a heat process that brings out the aroma and flavor inside the green coffee beans.  Roasting causes chemical changes as the beans are rapidly brought to very high temperature.  When they reach the desired level, they are quickly cooled to stop the process.  It takes an expert to do this as it takes split second timing. In general, roasts fall into one of four color categories – light, medium, medium-dark, and dark.

Light Roast

Light roasts absorb heat for the shortest time and appear light brown in color.  They are roasted until the beans pop or crack and expand at 356°F – 401°F, known as the “first crack”.  Light roasts have little or no oil on the them and the highest amount of caffeine.  They have a toasted grain taste and are acidic.

Medium Roast

Medium roasts are heated from 410°F – 430°F, just before the “second crack”.  They are medium brown, without oil on the surface and their taste is less acidic and more balanced.  The caffeine amount is slightly decreased.

  • Regular Roast
  • American Roast
  • City Roast
  • Breakfast Roast

Medium-Dark Roast

Medium-dark roasts have a richer, darker color with some oil on the surface and a slight bittersweet aftertaste.  The beans are roasted to the beginning or middle of the second crack at 435°F – 445°F.  The flavors and aromas become apparent, and the taste may be slightly bittersweet or spicy.

  • Full-City Roast
  • After Dinner Roast
  • Vienna Roast 

Dark Roasts

Dark roast beans are heated from 465°F – 485°F, to the end of the second crack and beyond.  They are dark brown with a shiny oil surface.  The coffee will generally have a bitter, smoky, sometimes burnt taste.  The amount of caffeine is reduced substantially.
