Gather your pine branches. Then give them a shake to remove any bugs and beasties that might be residing in the branches.
Next, pop the pine branches into your jar. You may need to cut them into smaller sections using scissors, if your branches are too long.
If you have any citrus peel, feel free to add these too for a extra fresh scent burst.
Next, pour in your vinegar until it reaches the top. Your branches and peel, if you added any, should be submerged.
Finally, pop the lid on, and let the ingredients infuse for at least two weeks in a cool, dark place. The cupboard under your kitchen sink is an ideal place for this. Two weeks would be the bare minimum. For stronger pine scented vinegar, leave the pine steeping for longer. I’ve left herbs and citrus infusing for as much as six months, for stronger smelling infused vinegar.
