At its simplest, roasting coffee is basic science "beans + heat + time = roasted coffee"... but to think that way would be to miss the point.  In reality it is a very personal thing, and every Roaster takes a different approach in order to extract the flavours they are looking for from the beans.  This is why we showcase a wide range of Roasters to you, so you can experience the subtle (and sometimes less subtle) differences that each one brings to the table.
