Freshness in coffee encompasses multiple aspects, from crop to roast date to brewing time. While freshness is a key focus in the specialty coffee industry, misconceptions can lead to unwarranted concerns and waste. Even older coffee can provide a satisfying cup if it has been sourced, roasted, packed, and stored correctly. Accepting this idea could lead to more frequent purchases of specialty coffee in cafes and supermarkets.
Specialty roasters prioritize freshly roasted coffee for optimal flavor. As a coffee subscription Founder, customers ask about freshness during transit. I’ll share insights and tips for resting and storing beans, while assuring you not to worry excessively about freshness. But How?
Resting coffee is crucial, as high CO2 levels can result in sour taste, astringency and extraction issues. To prevent inconsistencies, some of Specialty Cafés rest their coffees for up to six weeks to stabilize them before serving in their cafés.
Roasting generates CO2, which can hinder even extraction in very fresh coffee. Lighter roasts create less CO2 but denser beans, requiring more time for CO2 to escape and flavors to develop, often peaking around 2 weeks. As it has been widely assumed that different coffees stale at different rates due to their unique chemical and physical properties. Dark roasted coffees are more vulnerable to degradation due to their porosity and the natural oils that accumulate on their surface. Exposure to oxygen can cause these oils to become rancid.
the obsession with roast dates may be misplaced. Coffee’s freshness relies on both roasters’ efforts and consumers’ handling, including resting, storing and keeping in a cool, dark, dry environment. The focus should be on overall care, not just roast dates.
The ideal resting period varies based on personal taste and roaster recommendations. Experimentation and understanding your preferences will help you achieve the desired flavor profile. While resting enhances performance, don’t worry excessively; high-quality green coffee and proper roasting still yield good results even days after roasting
