Coco Polo’s chocolate bars, with ingredients having a shorter freshness life such as nuts, can last up to 12 months from time of manufacture. The other bars are recommended for 18 months. The “Best By Date” shown on the back of our bars reflect these time limits. Our bars, as with all chocolates, store best at 65-70 degrees, away from direct sunlight, in low humidity and sealed from surrounding smells that can affect their taste and texture. Therefore…Eat our chocolates as soon as you receive them!
