When buying your coffee, always ask when it was roasted. There are many common misconceptions when it comes to judging the freshness and absolute best time to experience roasted coffee at its peak (best tasting period). Coffee is at its absolute best when used a day or two after roasting, and if kept in an air tight container, the flavor should stick around seven to ten days. Old coffee beans may appear very oily, will have little or no aroma, or will take on a somewhat unpleasant aroma. Some coffee companies print the roast date on their bag! Very good for the consumer!
