What exactly makes coffee "bloom"?
Great question! Brewed coffee is an elixir of chemical components and soluble
compounds. I have read that there are well over 800 aromatics that have been
identified and I am sure that number has grown. The chemical make-up of brewed
coffee was affected by the growing conditions for the green coffee, processing,
degree of roasting, grinding for particle size as well as brewing temperature
and method. Brewed coffee continues to evolve or bloom, through aromatics rising
to the surface and escaping and acids combining and reforming into new ones.
These changes affect how we perceive acidity, sweetness and aroma in the cup.
