Benefits of a coffee grinder – the issue of oxidation

A great tasting cup of coffee is produced from whole coffee that's ground within a few minutes of brewing. The reason why coffee tastes so much better when it's just been through a coffee grinder, is that within two minutes, or so the experts claim, the coffee beans begin to oxidize, which is what changes the flavor. Most experts agree that the sooner you brew your coffee after you put it through a coffee grinder, the better your coffee will taste.
