Taste The Flavor
Your coffee will reach peak quality somewhere between 20 minutes to 3 days for brewed coffee and between 3-5 days for espresso. It’s usually not a good idea to brew coffee with beans that have just been roasted. Now, if you brew your coffee too soon after the roast you are likely to get unpleasant flavors that go along with the CO2 and other products that come from the roasting process.
The best taste should come around 5-14 days after the roast and you’ll be able to pull decent espresso 5-30 days after roasting.
