The difference between a room note and a flavor profile is the way in which they are experienced. A room note is the scent that fills the area around you when smoking a cigar, while a flavor profile is what the smoker experiences directly from the cigar itself. Room notes are often described as woody, spicy, sweet or earthy aromas that can linger in an area for some time after smoking has ceased. Flavor profiles on the other hand tend to be more varied and complex than simply one type of smell; instead, different aspects of taste such as sweetness, acidity, bitterness and body come into play. Flavors may change over time as the cigar burns down due to changes in combustion rate or temperature.
