Adapted from "The Wild Table" cookbook by Connie Green and Sarah Scott.
1. Place one cup of spruce or Douglas fir needles (stripped from the branches) and one-third of a 750-mililiter bottle of fine-quality vodka in a blender.
2. Blend at high speed for two minutes. Pour into a large clean jar.
3. Pour the remaining two-thirds vodka into the blender and swirl it around to gather any green residue on the sides and bottom of the blender. Pour into the jar and stir to combine. Cover and store in the refrigerator for one week.
4. Strain the mixture through a fine-mesh strainer and discard the green purée. Strain again through a coffee filter.
5. Pour the vodka into a clean bottle and store indefinitely in the freezer.
Makes one 750-milliliter bottle.
