Roasting coffee transforms the chemical and
physical properties of green coffee beans into roasted
coffee products. The roasting process is integral to
producing a savoury cup of coffee.
When roasted, the green coffee bean expands to
nearly double its original size, changing in color,
taste, smell and density.
Unroasted beans boast all of coffee’s acids,
protein, and caffeine, but none of its taste. It takes
heat to spark the chemical reactions that turn
carbohydrates and fats into aromatic oils, burn off
moisture and carbon dioxide, and alternately break down
and build up acids, unlocking the characteristic coffee
flavour.
We roast coffee on a smaller scale in order to
best control the freshness and roast level of the beans.
