If you are like most of the world, your morning coffee doesn’t look — or taste — like it did 15 years ago. Global coffee culture has experienced an enormous boom in recent years, with so-called “third wave” coffee shops and roasters pushing the boundaries of what is possible in both flavor and presentation. Much of the focus lies on the beans themselves — namely, bringing out the intricacies and distinct flavors that beans from different origins provide.

Third wave roasters work diligently to source coffee beans of the highest possible quaility. Because of the care taken by roasters, consumers now have unprecedented access to information about the flavor profiles they can expect from their morning cup. Flavors can range significantly based on origin — and single origin beans can create a cup of coffee more complex in flavor than wine. But this depends entirely upon roasters finding the right bean — grown and harvested in the right conditions — to maximize flavor.
