Perique (known for its strong, powerful, and fruity aroma) was developed in 1824 through the technique of pressure-fermentation of local tobacco by a farmer, Pierre Chenet. Considered the truffle of pipe tobaccos, it is used as a component in many blended pipe tobaccos, but is too strong to be smoked pure. At one time, the freshly moist Perique was also chewed, but none is now sold for this purpose. It is typically blended with pure Virginia to lend spice, strength, and coolness to the blend. - https://en.wikipedia.org/wiki/Tobacco#Types

The tobacco plants are manually kept suckerless and pruned to exactly 12 leaves through their early growth. In late June, when the leaves are a dark, rich green and the plants are 24–30 inches (60–75 cm) tall, the whole plant is harvested in the late evening and hung to dry in a sideless curing barn. Once the leaves have partially dried but are still supple (usually less than 2 weeks in the barn), any remaining dirt is removed and the leaves are moistened with water and stemmed by hand. The leaves are then rolled into "torquettes" of approximately 1 pound (450 g) and packed into hickory whiskey barrels. The tobacco is kept under pressure using oak blocks and massive screw jacks, forcing nearly all the air out of the still-moist leaves. Approximately once a month the pressure is released, and each of the torquettes is worked by hand to permit a little air back into the tobacco. After a year of this treatment, the perique is ready for consumption, although it may be kept fresh under pressure for many years. Extended exposure to air degrades the particular character of perique. The finished tobacco is dark brown - nearly black - very moist with a fruity, slightly vinegary aroma.[2] The fruity aroma is the result of hundreds of volatile compounds created by anaerobic fermentation of the tobacco. Many of these are responsible for the flavors of fruits and are often found in wine.[3]

There are a number of varieties, even a Nicotiana rustica with 9% nicotine, but that Perique sounds like a pretty fun fermentation project. You'd need to get some seeds or clones. Get a nice sized grow tent and equipment, and you'd soon be turning out your own artisan tobacco. 'Soon' being relative, but still.

https://dutchpipesmoker.com/tag/flue-curing/ - Everything you ever wanted to know about flue-curing, and all the types of Virginia tobacco varieties and blends. Interesting process that turns the leaves bright yellow.

Well, now I've run out of time to do kratom and tea. Have never looked at the tobacco growing and processing end of it before. Pretty interesting, especially that fermentation drying process. Almost like some types of tea.
