There is something about coffee that makes a lot of people so fond of it. Perhaps it's the rich aroma that wakes the senses up or its caffeine content, which helps coffee drinkers focus better on whatever task is at hand. Whether it's pour-over, espresso, cappuccino or cold brew, coffee never fails to add that extra zing one needs as they go about their day.

While there is a large number of food holidays throughout the year, National Coffee Day, which falls on Sept. 29, holds a special significance because of the many stores, cafes and restaurants that offer freebies and discounts in honor of the occasion.
