The humble green coffee bean - a power-packed seed contains a world of aroma and flavor possibilities

Today’s blog will be short and sweet. What’s in a coffee bean? Have you ever wondered about the physical composition of a coffee bean? Perhaps not, but you may be surprised to learn of the amazing amount of organic materials, chemical compounds, sugars, oils, and other physical properties. A single coffee bean has more than one million cells made up of over 850 variable known compounds that appear during the roasting process.

Just a few of these volatile properties are:

  • Water (around 11% in green coffee) - moisture content in green coffee is responsible for the coffee’s ability to withstand the high heat applied during roasting. After roasting there is less than 2% moisture left in the coffee. The weight of the coffee is reduced by around 20% from pre to post-roast.

  • Sugars (6-9%) - mostly Sucrose provides sweetness in the cup and also contributes to the coffee’s acidity.

  • Lipids (16%) - contribute to coffee’s aroma and mouthfeel.

  • Proteins & Amino Acids (10-13%) - interact with sugars during roasting causing the browning of the coffee known as the Maillard Reaction, which contributes to coffee’s bitter-sweet, roasty, meaty and baked aromas.

  • Caffeine - around 1% of green coffee weight, but contributes to 10% of the bitterness experienced in brewed coffee.

  • Organic Acids - primarily chlorogenic acids (7-10%) which contribute to coffee’s acidity, bitterness, and astringency.

  • Aromatic compounds - over 200 aromatics in green coffee explode to more than 850 in roasted coffee making the humble coffee bean one of the most complex aromatic and sensory-stimulating beverages in existence!

Take time today to enjoy a delicious cup of Vienna coffee and pause a moment to enjoy all of the wonderful aromas, tastes and sensations that the humble coffee bean provides us each and every day.

It’s a GREAT day for coffee!!
