Tobacco Moisture and Pre-Smoke Drying

Tobacco moisture is one of the most fundamental factors determining the quality of a pipe smoke. The same blend can produce very different results depending on its moisture level: overly moist tobacco is hard to keep lit, needs constant relighting, and produces a heavy, steamy smoke in the bowl; overly dry tobacco, by contrast, burns fast and hot, losing a significant share of its aroma.

Since most factory-packed tobaccos are sold at a moisture level above ideal smoking moisture, to keep them from drying out in transit and storage, experienced smokers have made a habit of drying their tobacco for a while before packing. Managing moisture correctly largely eliminates the "fighting wet tobacco" problem that ranks among the common beginner mistakes.

Ideal Moisture and the Pinch Test

Sources generally give the ideal moisture level for smoking as around 12-15% by weight; while some smokers prefer it drier, others consider values up to 18% acceptable. Since the exact figure varies with personal preference and blend type, rather than trying to measure moisture at home, the practical method known as the "pinch test" is used: a pinch of tobacco is lightly squeezed between thumb and forefinger, then released.
