Air exposure of 6 to 8 weeks (sometimes extended to 3 or 4 months) is necessary when tobacco is cured by exposure to the sun and air. It is claimed, however, that this method of curing preserves far better the natural flavor of the leaf; and, where flavor and aroma are highly important, this method is always preferred. Hence all cigar leaf tobaccos are cured by exposure to natural sunlight and not by artificial heat.
“Air” curing as distinct from sun curing is generally done in open sheds which are thoroughly ventilated and kept as far as possible at a temperature of about 75° F. The leaf is usually allowed to cure while attached to the stalk, but Florida curers generally prefer to strip the leaf and treat it separately. The finer classes of pipe smoking tobaccos are air cured.
After the curing is completed the color of the leaf is usually fixed. Generally speaking, the riper the leaf the lighter will be its color when cured. Thus the bottom leaves of the plant will be lighter in color than the upper leaves because they are more mature.
