Black Cavendish is a style of tobacco processing that produces a mild, very dark tobacco, that can be used for pipe blending. Black Cavendish is notable for its ability to readily absorb added flavors for aromatic blends. Unflavored, it also makes a wonderful blender when mixed with stronger tobaccos. Smoked straight and without added flavor, it is likely the mildest, bite-free pipe tobacco that you will ever taste.
What makes Black Cavendish is prolonged steaming.
The difference between homemade Black Cavendish and the Black Cavendish that you can purchase at a tobacconist rests in the additives (and perhaps the quality of the tobacco). Most commercial Black Cavendish is flavored (often with vanilla), and usually contains propylene glycol and glycerin, both used as humectants (so it feels fresh forever--like a Twinkie). Flavorings and humectants, almost without exception, increase tongue bite. Your homemade Black Cavendish will have none, unless you choose to flavor it.
You can use any variety of tobacco.
I chose some of BigBonner's excellent air-cured Maryland 609 for this batch. Maryland tobaccos are famous for their absorptive capacity as well as their mildness and low nicotine. You can use any variety. Each will lend its own attributes to the final product.
This is the change we are looking for. MD609 before and after.
In the steps that follow, I've started with about 12 leaves of air-cured MD609. The stems were removed, and the strips were placed within a stainless colander which is nested on top of a pot of gently boiling water.
Find a lid that will fit inside the colander, but will leave a small number
of holes still open above the rim of the pot.
I steamed the leaf for a total of 7 hours. The longer it steams, the darker the leaf will become. The odor for the first couple of hours is not very appetizing. This changes to a soft, fruity aroma later on. Be sure to check the water level in the pot from time to time, and replenish it as needed.
Appearance after only 3 hours of steaming.
Once the leaf is as dark as you'd like, place the colander into the sink and allow it to drain. When most of the excess water has drained, hang the individual leaf strips on a plastic clothes-hanger to dry overnight. This batch fit on a single hanger, which I suspended above the sink. The goal at this point is to dry it down into high case (as opposed to soggy).
With the still-soft leaf, create an even stack, about the size of a sandwich.
This can be a quick, messy stack. Just make it an even thickness.
Transfer the stack into a quart-size Freezer Ziplock for pressing.
Press under about 50 pounds for a few hours.
This is a wall-mounted lever press exerting ~50# (~2 psi).
You could accomplish the same thing between two boards, with a 5 gallon
water-filled bucket on top (~40#).
The goal of the pressing is to allow the layers to partially stick together. In this state, it will mold rapidly, so don't store the resulting press cake without further drying.
From a dozen leaves, I produced a press cake about 1/2" thick.
