Sunday, October 10, 2010I live in a wooded area and had planned a while to distil the leaves of pine for essential oil. The weather cooperated this weekend to get back to distil.
For this distillation I had chosen the spruce. I took some branches of very young trees growing naturally in the forest. With a folding crate full of freshly cut branches I went to work.

This is the silver fir Albies alba. http://www.bomengids.nl/zilversparren.html
The difference with the pine, which are very common and mostly does well on poor sandy soils, is very obvious.
As preparation for the distillation, I cut the branches into smaller pieces of mostly young twigs with needles.
Setting the cooling gave no problems and after more than two hours, I stopped distilling.At that point there was no oil left, and I had six bottles filled with hydrosol.
The amount of spruce branches in the alembic was not weighed. So a exact yield was incalculable. What I know is that I filled the alambic with about 7 liters of spruce twigs and distilled about 7 mL of essential oil.The oil had a very surprising pleasant smell. I had expected a more pine-like odor. The spruce essential oil had a citrus odor. If you read the books about it is this true. Fir needle oil contains pinene Santen and over 30% limonene, a terpene that a major constituent of citrus oils. Reason enough for me in the near future to distil more conifer species .
