How quickly after roasting does coffee lose its flavor?

The rate at which coffee loses its flavor after roasting depends on several factors, including:

* Roasting level: Lighter roasts tend to degrade faster than darker roasts.

* Storage conditions: Exposure to air, light, heat, and moisture accelerates flavor loss.

* Bean type: Different coffee beans have different chemical compositions, leading to varying rates of degradation.

* Grind size: Finely ground coffee loses flavor faster than coarsely ground coffee due to increased surface area exposed to air.

General guidelines:

* Freshly roasted: Coffee is at its peak flavor for the first 1-2 weeks after roasting.

* Optimal shelf life: Coffee will maintain most of its flavor for up to 3-4 weeks after roasting if stored properly.

* Beyond the peak: After 4 weeks, coffee will start to lose its freshness and flavor more rapidly.

Tips for preserving coffee flavor:

* Store in airtight containers: This will minimize exposure to air and moisture.

* Store in a cool, dark place: Avoid direct sunlight and heat.

* Grind beans just before brewing: Grinding beans fresh releases aromas and flavors that quickly dissipate.

* Buy small quantities of coffee: This ensures you're always using freshly roasted beans.

While coffee will lose its peak flavor after a few weeks, it's still perfectly drinkable for several months if stored properly.
