On a recent trip to Joaquin Miller Park in Oakland, I gathered some redwood needles with the goal of somehow capturing their scent. As a way of extracting their aromas, I infused the redwood needles in fermenting mead.
When exposed to air, acetic acid bacteria will convert any alcoholic liquid into vinegar. Through this process, the redwood infused mead turns into a redwood vinegar. (Left exposed to the air for a prolonged time, however, this vinegar will then oxidize, undergoing a number of interesting changes in flavor but eventually destroying those most desirable.)
Begin by heading outside, to wherever trees grow freely, and gather some artifacts of a particularly aromatic plant. Though I collected redwood needles, this method would work with any conifer; it may work with some deciduous leaves as well.
Step 1: Mix Honey and Water
If you have a scale, weigh out water and honey at a 4:1 ratio. If not, this ratio works out to be roughly a pound of honey per half gallon of water. Make enough to comfortably cover whatever quantity of redwood (or other conifer) needles you've gathered.
Put a lid on and shake until the honey has evenly dissolved.
