What is the 15 15 15 rule for coffee?
The 15–15–15 coffee rule explains why freshness matters at every stage of your coffee’s journey. Green coffee is best used within 15 months of harvest, roasted coffee tastes its best within 15 days of roasting, and once you grind your beans, you’ve got about 15 minutes before aroma and flavour start to fade. But as true coffee lovers know, great coffee can be delicate. From the moment coffee beans are roasted to the time they reach your cup, they face four relentless enemies: air, moisture, heat, and light. Each one can dramatically affect the flavour and quality of your coffee if not properly managed.Not all coffee beans taste the same. The soil and climate where they grow shape their flavour. In regions like Chikmagalur, Coorg, and Nilgiris, coffee grows under dense tree canopies, shielded from direct sunlight. This slow-growing process results in beans with higher acidity and more complex flavour notes.Air, Light, Heat, Moisture – The Four Enemies of Coffee 😈 Think of coffee like a fresh ingredient, not a pantry staple. The moment it’s roasted, coffee begins to oxidize, exposed to air, flavour compounds start to break down, turning what was once vibrant and complex into something flat and dull.Coffee is fresh produce, and its enemies are oxygen, light, heat, and moisture. To keep coffee fresh, store it in an opaque, airtight container at room temperature. You can store it that way for up to a week. For the best results, coffee should be ground just before brewing.
