A process for harvesting organic material recovers sugars, proteins, aromatics, organic acids and mixtures thereof, from the sapwood of trees or recently pruned sections, e.g. branches. The process involves drilling entry and exit ports to access the sapwood layer and the use of spiles, driven into the ports, to create fluid tight seals for the tubing, which delivers and recovers the solution, which solubilizes the harvested organic material and flows through the sapwood layer. The close proximity of entry and exit ports permits the flow of a pressurized solution. The recovered pumped solution or products therefrom, if desired, can be used in a fermentation medium to prepare products, e.g. alcohol, fatty acids.
