Burley, Black Cavendish and Virginia
Strength i STRENGTH: the overall strength of the tobacco. This includes the strength of its taste and its nicotine content.
Flavoring i FLAVORING: primarily for aromatic blends, this refers to the "topping" but sometimes also to the "casing" added to the tobacco. This will account for detectable flavors like cherry or chocolate.
Taste i TASTE: although a wholly subjective measure, it is one of the most important in that it measures how tasty smokers find the blend. Like food, some dishes are tastier than others.
Room Note i ROOM NOTE: a measure of the ambient scent/smell a blend puts out for those around the smoker. Basically, how strong does it smell, and how pleasant do those around you find that smell. The stronger, generally the less pleasant. You can also call this the "wife rating."
