Understanding Coffee Freshness

Freshness in coffee is a multi-faceted concept, encompassing several aspects such as the roast date, the peak flavor period, and the optimal window for consumption. Coffee is a perishable product, and its flavor profile evolves from the moment it is roasted. Understanding this evolution can help you enjoy your coffee at its best.

The Freshness Study

To provide you with the best coffee experience, we conducted a detailed study on the freshness of our Ethiopian Washed and Bolivian Natural coffees. Here are the results of our study, measured in the scores of each coffee over a 60-day period post-roasting:

Peak Flavor Period

Both our Ethiopian Washed and Bolivian Natural coffees reach their peak flavor around 7 to 14 days post-roast and holds it until day 40! During this period, the flavors are most balanced and vibrant, offering a rich and nuanced cup that highlights the unique characteristics of each origin.

Fresh Cup Threshold

Our study indicates that both coffees maintain a high-quality flavor profile for up to 40 days after roasting, scoring above the "fresh cup" threshold of 87. This means that while the peak flavors are enjoyed between 10 to 40 days, the coffee remains fresh and enjoyable for nearly 7 weeks.

Decline in Freshness

After 50 days, both coffees begin to show a gradual decline in their flavor scores. By 60 days, the Ethiopian Washed drops to 85.75 and the Bolivian Natural to 86. While still drinkable, the complex and vibrant flavors that define these coffees start to diminish.

Maximizing Freshness

To ensure you enjoy the freshest and most flavorful cup of coffee, here are a few tips:

  1. Buy Fresh: Purchase coffee in small quantities that you can consume within a few weeks. This helps to ensure you always have fresh coffee on hand.

  2. Proper Storage: Store your coffee in an airtight container in a cool, dark place. Avoid exposure to air, moisture, heat, and light, as these elements can accelerate the degradation of coffee.

  3. Grind Just Before Brewing: For the best flavor, grind your coffee just before brewing. Pre-ground coffee loses its freshness much faster than whole beans. However, if your coffee is too fresh, pre-grounding 2-8 hours before can help degas your coffee faster for single dosing.

  4. Brewing Methods: Experiment with different brewing methods to find the one that best highlights the flavors of your coffee during its peak freshness period.
