Explicit 'Roasted On' Date (Within 14β45 Days)
Look for an exact calendar roast date, not a distant 'Best By' stamp. Specialty coffee reaches peak sweetness between day 7 and day 35 after roasting.
If the bag only lists a 'Best By' date 12 to 24 months in the future, the roaster is concealing that the beans may already be months old and stale.
