The sap is sweet, and therefore provides food for many organisms, insects or bacteria.

Uh, not really a style twist: you don't know maple syrup or birch sap (birch water commercially)?
Ahmed wrote:I don't know if that answers your question, Adrien, but there are two stages in the drying of wood: drying and drying proper. The first corresponds to the disappearance of the water present between the cells, while the second, which then intervenes, concerns the water contained in the cells. This distinction can have some interest in the case of lumber since by controlling the drying speed one avoids part of the deformations and especially the production of slots which devalues the studs.
For firewood, this has absolutely no importance, since only speed can have an interest and slots are rather an advantage by allowing faster drying due to the increase in evaporation surfaces.
It is absurd to focus on an ideal and universal drying time, since it essentially depends on variable factors ...
A good way to have dry wood quickly is to store it in a basic greenhouse, with an air inlet at the base and a calibrated outlet in the upper part: no need for regulation and the operation accommodates this device approximate: the air heats up, loads with humidity and leaves at the top to be replaced by cooler and drier air ...
Another device also gives good results, but remains anecdotal in that it requires much more difficult conditions to meet: on a wall of the greenhouse an exchange surface is crossed by a stream of cold water (typically, stream mountain) and causes the water evaporated in the greenhouse air to condense; the condensates are then evacuated outside ...
