Section 1: Understanding Coffee Aromas

The Fresh Coffee Aroma

Fresh coffee is rich with numerous aromatic compounds contributing to the complexity of its scent. From floral and fruity notes to caramel, nutty, and chocolatey hints, these aromas are what make fresh coffee so enticing.

The Stale Coffee Smell

When coffee goes stale, oxidation, moisture, temperature changes, and time can degrade these aromatic compounds, leaving a dull, flat smell. This cardboard-like scent is a tell-tale sign that your coffee has lost its freshness.
