incense Making, Vietnam: Incense stick production is, in a very real way, a seasonal production in Vietnam, with production ramping up between the months of November until middle of January as the world prepares for the Buddhist calendar New Year celebrations (Tet in Vietnam, Chinese New Year etc) in the beginning of February. The literally hundreds of small factories, some no more than the members of just one family, will produce, in a little over 2 months, billions upon billions of incense sticks, starting from the selection of the right types of bamboo sticks all the way to the addition of the burning paste and the packaging.
