Virginia can vary. Yellow, or blond, Virginia is sweet and "grassy" or "earthy". Red Virginia is still sweet, but not as grassy. Dark Virginia is not quite as sweet but richer. Virginia tobacco has a natural sugar that grows into the leafs, thus they are sweet. It is mostly Flue Cured, although sometimes it is Fire Cured to add a smokey texture. HHV Huntsman was a Virginia extract, and pipe tobaccos like C&D Briar Fox and Yorktown are a couple of examples. McClellan Stoved Virginia (no longer available) was an excellent Fire Cured Virginia.
Burley is grown specifically to not have natural sugars. This makes the leaves lighter in color. Many claim that Burley has a "nutty" taste. White Burley is vary mild, and is used as a mixer with Virginia tobaccos, while stronger Burley is often referred to as "old codger Burley". Like Virginia tobaccos, Burley is mostly Flue Cured but occasionally Fire Cured.
@Bronze has extracted Fire Cured Kentucky Burley, while C&D Crooner and Haunted Bookshop are considered to be "Burley first" blends.
Cavendish is a process where Virginia and/or Burley tobaccos are pressed into a cake, then steamed to enhance the natural sweetness of the tobacco. Sometimes the tobacco is treated with a top note before pressing, making it a Cherry, Vanilla, Butterscotch, Caramel, or whatever flavor is desired mild and sweet tobacco for blending.
Perique is a white tobacco grown on the Delta Plain of Louisiana. Carefully harvested, then pressed until the air is removed and left to ferment for a year. It comes out dark, wet and spicy. H&H Louisiana Red and Anniversary Cake are Virginia/ Perique, or VaPer, blends.
Turkish, or Oriental, tobacco is a name given to a small leaf variety of tobacco grown in the Middle East. It is normally sun cured, and is used extensively in cigarette production. Peter Stokkebye's 84 Turkish is a Virginia/ Turkish blend, while Roll-Your-Own (RYO) cigarette tobaccos like Ryan and Daughters, and OHM Turkish blends, feature these small leaf sun-cured tobaccos.
Latakia tobacco is a Turkish tobacco that is partially sun cured, then hung in barns over selected smoldering wood and herbs. It is a very strong and distinctive taste that is usually added in small quantities as a 'condiment' flavor to a tobacco blend. English Blends such as Sutliff's Voodoo Queen, and Dunhill's Early Morning and Nightcap are Latakia blends. Though I tend to stay away from the stronger English blends, H&H Midtown Chestnut has a small condiment of Latakia that is noticeable as a 'black licorice' taste on the exhale.
Just my observations and tastes. When you start adding cigar tobaccos like Maduro and Connecticut Leaf, the options grow exponentially.
