The Art Of Brewing Freshly Roasted Coffee Beans

Coffee lovers are often advised to use fresh, quality beans to get the best cup of coffee. However, the term fresh is relative and can mean different things to different people. While some coffee roasters claim that coffee is best when it's freshly roasted or fresh out of the roaster, others argue that coffee needs to rest for a few days to achieve its optimal taste. So, how long should coffee rest after roasting before brewing?

Coffee beans should rest for 1-5 days after roasting

The amount of resting time depends on the type of roast. Darker roasts tend to degas faster than lighter roasts, so they only need to rest for 1-3 days. Lighter roasts may need at least 5 days or even up to 7-14 days to reach their optimal taste profile.

During the resting period, freshly roasted coffee will continue to evolve and develop its unique flavour profile. The taste will change over time, so it's important to find the right balance between degassing the CO2 and retaining the volatile aromas. This "sweet spot" can vary depending on the coffee roast, bean density, size, processing method, and varietal.

Some coffee beans may even benefit from longer resting periods of several weeks or more. However, it's generally recommended to consume coffee within a few days to a few months after roasting to ensure the best flavour and avoid staleness.

Additionally, proper storage is crucial to maintaining the quality of roasted coffee beans. They should be stored in airtight containers, such as bags with one-way valves, to allow CO2 to escape while preventing contact with oxygen, which can cause flavour deterioration.

Lighter roasts need longer to degas

When it comes to coffee, there are many variables that affect the brewing process and the taste of the final product. One of the most important factors is the resting time of the coffee beans after roasting. While some people believe that freshly roasted coffee is the best, this is not always the case. The resting time, or degassing period, allows the beans to release excess carbon dioxide (CO2) built up during roasting, which can interfere with the extraction process and negatively impact the taste.

Lighter roasts, in particular, require a longer degassing period compared to darker roasts. This is because lighter roasts maintain more bean integrity, resulting in a slower release of CO2. The resting time for lighter roasts can range from 5 to 14 days or even longer, depending on the specific coffee and personal preference. During this period, the coffee will continue to evolve and develop its optimal taste profile.

The longer degassing time for lighter roasts is essential to achieving the best flavour. If brewed too soon after roasting, lighter roasts may result in a cup of coffee with a woody, bitter, or flat taste due to the presence of excess combustion elements. Allowing the beans to rest gives the CO2 time to dissipate, ensuring that the water can properly extract the desired flavours during brewing.

Additionally, the extraction method can also impact the resting time. For espresso, which is a more intense and pressurized brewing method, it is generally recommended to give the coffee a longer rest, especially for lighter roasts. For gentler brew methods like drip or pour-over, you may be able to use the coffee a little earlier, but still allowing for some resting time to ensure optimal flavour.

In conclusion, when it comes to lighter roasts, taking the time to let the beans rest and degas is crucial for achieving the best-tasting cup of coffee. While it may require some patience, the result will be a more balanced and enjoyable brew.

Darker roasts have a shorter resting time

The resting time of coffee depends on its roast level and roast speed. While some people prefer to brew their coffee immediately after roasting, others believe that coffee needs to rest for a while to reach its optimal taste.

Coffee beans release CO2 during the roasting process, which can interfere with the extraction process and make it harder to brew a tasty cup. The CO2 can prevent hot water from coming into contact with the coffee particles, resulting in a weaker brew. Therefore, it is important to let the coffee rest and degas before brewing.

The resting time for coffee also depends on the type of brew. For espresso, it is recommended to give the coffee a longer resting time before subjecting it to an intense, pressurized brewing environment. For more gentle brew methods like drip or pour-over, you can use the coffee a little earlier.

Some people believe that coffee is like a "fresh" product, and it needs to be consumed within hours of roasting to get the best flavors. However, this is not true. Coffee is an aged product and can remain stable for months. The optimal taste of coffee happens at some point after it has been roasted and had a chance to rest and degas.

Coffee beans can be rested for up to 2 weeks

The resting time of your coffee will also depend on how you plan to brew it. For espresso, it is generally recommended to give the coffee beans a bit more time to rest before subjecting them to an intense, pressurized brewing environment. For drip or pour-over coffee, you can start using your beans a little earlier (after 4-7 days).

It's worth noting that the idea that coffee needs to be consumed within hours of roasting to get the best flavors is a common misconception. In reality, coffee is more similar to an aged product like wine, and it can take hours or even weeks for coffee to ripen and develop its optimal taste profile.

While there is no definitive answer to the optimal resting time for coffee beans, experimenting with different rest times can be a great way to find the sweet spot for your particular coffee and brewing method.

Coffee beans can be rested for a minimum of 24 hours

Resting coffee is important because, if brewed too soon after roasting, the coffee will be harder to extract and will have a woody, bitter, and flat taste. This is because the CO2 in freshly roasted beans interferes with the extraction process by preventing hot water from contacting the surface of the coffee particles. This can be seen when brewing a pourover of freshly roasted coffee, as the mass of bubbles will well up from the grounds when the hot water hits them.

However, it is also important not to wait too long to brew your coffee, as the aromatics will begin to degrade and be lost, resulting in a loss of freshness. For most coffees, this happens in a window of 4-14 days after roasting.
